}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
A time-traveller (the sphere-like thing) visits us/the present from the far future. Spiders are their current craze, [http://www.imdb.com/title/tt0107290/ much] [[1211|as]] [https://en.wikipedia.org/wiki/Dinosaur dinosaurs] [http://www.imdb.com/title/tt0369610/ are] [https://www.ncbi.nlm.nih.gov/pubmed/25870766 currently] (at the time the comic was released) [http://dinosaurworld.com/ to] us.&lt;br /&gt;
The time-traveller immediately spots a spider, awestruck to see the object of its obsession in the living flesh.&lt;br /&gt;
Since spider webs don't fossilize, the time-traveller is surprised to see the spider in a web. There was no possible hint of spiderwebs in the fossil record, from which the time-traveller gathered all its knowledge.&lt;br /&gt;
&lt;br /&gt;
We, with our current knowledge, know that webs are an essential part of a spiders life. Making sense of a spiders life is practically impossible without including their webs. However, the future-people have done so until now; discovering how wrong they are is bound to become an intense experience for them.&lt;br /&gt;
&lt;br /&gt;
[[Megan]] immediately connects the time-travellers [[1053|realisation]] to our current understanding of dinosaurs:&lt;br /&gt;
If future-people think they understand spiders, while missing something as essential (but non-fossilising) as their web, what are ''we'' missing about dinosaurs?&lt;br /&gt;
[[Cueball]] quickly catches on, and both ask if they can borrow the time-machine to have their mind blown about dinosaurs much as the time-traveller is experiencing right now about spiders.&lt;br /&gt;
&lt;br /&gt;
The title text calls back to one of Randall's favorite facts (see [[1211: Birds and Dinosaurs]]) - that birds are technically part of the clade ''Dinosauria''. Birds do lots of weird stuff - from [https://www.youtube.com/watch?v=eakKfY5aHmY starlings flocking] to [https://www.youtube.com/watch?v=W7QZnwKqopo the dances of birds of paradise] to [https://www.youtube.com/watch?v=VjE0Kdfos4Y lyrebird mimicry] to [https://en.wikipedia.org/wiki/Stomach_oil petrels puking stomach oil], [https://www.youtube.com/watch?v=ii_w8og8RXg]. Dinosaurs would have had equally strange behaviors, but it's basically impossible to tell from the fossil record. All we know is that they had features such as display feathers, {{w|neck frill|neck frills}}, and crests which likely played a role in mating and territorial shows.&lt;br /&gt;
&lt;br /&gt;
This is the second comic with special mentioning of a science related directly to spiders, the first being [[1135: Arachnoneurology]].&lt;br /&gt;
&lt;br /&gt;
Similar talking floating energy dots have been seen before in [[1173: Steroids]] and [[1450: AI-Box Experiment]]. They are clearly not the same time traveller as in this comic.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[A seven-panel comic featuring Cueball, Megan, and a time-traveler from the distant future, possibly from somewhere other than Earth. The time-traveler is depicted as a solid, floating black dot surrounded by six outwardly-curved segments, surrounded by small dots. In the second panel, the depiction is slightly different.]&lt;br /&gt;
&lt;br /&gt;
:[The time-traveler floats on the left facing Megan who is in the center facing left. Cueball is to Megan's right and also facing left.]&lt;br /&gt;
:Time-traveler: I'm here from the distant future!&lt;br /&gt;
:Megan: Cool! What for?&lt;br /&gt;
:Time-traveler: ''Spiders!''&lt;br /&gt;
&lt;br /&gt;
:[A close-up of the time-traveler, depicted as a diffuse black smudge surrounded by seven narrow rays with irregular dots between the rays.]&lt;br /&gt;
:Time-traveler: We've learned about your planet's spiders from fossils.&lt;br /&gt;
:Time-traveler: There's a whole spider craze. We have spider theme parks, spider movies, spider costumes...&lt;br /&gt;
:Time-traveler: Such beautiful animals!&lt;br /&gt;
:Megan (off-panel): I guess...&lt;br /&gt;
&lt;br /&gt;
:[Back to the time-traveler, Megan and Cueball as shown before. Megan is gesturing left, past the time-traveler.]&lt;br /&gt;
:Time-traveler: Now we've got time travel, so I'm here to see one for myself!&lt;br /&gt;
:Megan: Sure! There's one over there!&lt;br /&gt;
&lt;br /&gt;
:[The time-traveler floats over a leafless plant. A spider web is strung between the border of the left panel and the leafless plant. A spider is in the center of the web.]&lt;br /&gt;
:Time-traveler: ''Woowwww!''&lt;br /&gt;
:Time-traveler: What's that giant net it's caught in?&lt;br /&gt;
:Megan (off-panel): You mean its web?&lt;br /&gt;
:Time-traveler: Its what?&lt;br /&gt;
&lt;br /&gt;
:[Back to a scene similar to the first, depicting the time traveler, Megan and Cueball]&lt;br /&gt;
:Megan: Oh, right, fossils. So you wouldn't know about...&lt;br /&gt;
&lt;br /&gt;
:[In a frame-less panel only Megan is shown facing left.]&lt;br /&gt;
:Megan: ...&lt;br /&gt;
&lt;br /&gt;
:[Again a scene similar to the first.]&lt;br /&gt;
:Megan: Oh my God. Dinosaurs must have been ''so weird''.&lt;br /&gt;
:Cueball: Holy crap, yeah.&lt;br /&gt;
:Megan: Listen, can we borrow your time machine?   &lt;br /&gt;

I think the comics explanation should include dieticians.[[Special:Contributions/162.158.49.12|162.158.49.12]] 14:58, 10 October 2016 (UTC)&lt;br /&gt;

If it was White Hat saying this, I'd expect him to be literally able to eat whatever he wants, even items that are not normally edible. It is not, however (which is strange, because, even aside from that alternate interpretation, it sounds a lot like his style). --[[Special:Contributions/172.68.11.36|172.68.11.36]] 02:56, 11 October 2016 (UTC)&lt;br /&gt;
: I'd say in that case it had to be Beret Guy instead of White Hat. [[User:Elektrizikekswerk|Elektrizikekswerk]] ([[User talk:Elektrizikekswerk|talk]]) 07:31, 11 October 2016 (UTC)&lt;br /&gt;

I have one of those metabolisms where if I eat more than what I need, I sweat a lot during the night and I never fatten. I'm always underweight. é_è [[User:Seipas|Seipas]] ([[User talk:Seipas|talk]]) 09:07, 11 October 2016 (UTC)&lt;br /&gt;
&lt;br /&gt;
The explaination is mistaken. It is indeed possible to eat and not gain weight, and well document and most parts of it understood by medicine. Excess energy is only stored as fat if the body is stressed, you can piss out the sugar or the intestines can absorb less. The problem with the idea is that is hard to impossible to correct what your body does in this regard which makes is a red herring for the already overweight. [[Special:Contributions/162.158.87.11|162.158.87.11]] 16:45, 11 October 2016 (UTC)&lt;br /&gt;
&lt;br /&gt;
:It's even worse: if you try some diet to reduce weight and you start feeling hungry due to this diet, your body will interpret it as signal that it needs to work harder to preserve and/or obtain energy. When you stop the diet, you will then gain even more weight, which is also known as {{w|Yo-yo effect}}. Overweight people who already tried multiple diets, some of them based on bad ideas, will typically get more fat from the same food than people who never cared. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 13:37, 13 October 2016 (UTC)&lt;br /&gt;
&lt;br /&gt;
[https://xkcd.com/1475/ Technically], Cueball says he can eat &amp;quot;'whatever I want,&amp;quot; which would imply he could eat traditionally non-edible items. I don't think this is actually intended based on context, but... {{unsigned ip|108.162.218.154}}&lt;br /&gt;
:Mentioned already in my comment above (and the discussion after it). It would probably have been intended if that was Beret Guy, but that's not Beret Guy. --[[Special:Contributions/172.68.11.36|172.68.11.36]] 20:48, 14 October 2016 (UTC)&lt;br /&gt;

It may be coincidence but this comic was published the day before the Yom Kippur (Day of Atonement) Jewish fast. There was a reference to the Jewish calendar a few comics ago. {{unsigned ip|141.101.104.123}}&lt;br /&gt;
&lt;br /&gt;
This is stated too strongly.

&lt;div&gt;'If the Moon is in the night sky, the Sun must be somewhere &amp;quot;below&amp;quot; the horizon on the other side of the Earth.' Funny how people still talk as if Earth is the center of the universe. More correct would have been to say something about &amp;quot;Earth's rotation&amp;quot; and stuff.&lt;br /&gt;
&lt;br /&gt;

I can't find any photoshopped Moon that looks like the last image. Somebody has to make one. --[[Special:Contributions/162.158.92.207|162.158.92.207]] 13:22, 26 September 2016 (UTC)&lt;br /&gt;
&lt;br /&gt;
: Randall uncharacteristically missed an opportunity for pointing out additional errors that people make:  It's interesting to note that you can get a decent estimate of the artist's latitude by looking at how they draw a crescent moon.  In equatorial cultures, the crescent looks like a cup or a boat - and they interpret it like that.  But if you look at most english language children's books, the crescent looks like a letter 'C' or a 'D' with a human face - suggesting that they were probably made in the tradition of northern Europe.  When I first moved from the UK (more or less a 'C'-shaped crescent moon) to the southern USA (more like Randall's depiction of the correctly-drawn crescent with the points at a roughly 45 degree angle to the horizon) - I subconsciously felt that the moon &amp;quot;looked wrong&amp;quot; - it was only much later that I understood the reason.&lt;br /&gt;
&lt;br /&gt;
: Furthermore, this rotation of the moon relative to the observer also explains why &amp;quot;The man in the moon&amp;quot; is a common trope caused by the pareidolia interpretation of the cratering patterns of the moon in northern cultures.  But in southern cultures, people tend to see a rabbit in those full-moon patterns - and that has become the source of many of their stories.&lt;br /&gt;
&lt;br /&gt;
: Now that I'm more acutely aware of this - it's interesting to note how many movies get the orientation of the moon wrong for the location that their story is supposedly set in!  [[User:SteveBaker|SteveBaker]] ([[User talk:SteveBaker|talk]]) 13:41, 26 September 2016 (UTC)&lt;br /&gt;
::In Japan, for example, the patterns are interpreted as a rabbit making mochi (a sort of dense dumpling made from rice pounded into a powder) on the moon - the Sea of Tranquillity forming the head, and the Sea of Clouds forming part of the pestle in which the rabbit is pounding the rice. {{unsigned ip|188.114.102.167}}&lt;br /&gt;

: Not quite sure how to add this but Gibbon is the author of The Decline and Fall of the Roman Empire - or a type of Ape. It is not a phase of the moon. Also I think the moon depicted is Waning. [[Special:Contributions/141.101.98.113|141.101.98.113]] 14:02, 26 September 2016 (UTC)&lt;br /&gt;

::: Indeed - but that's pretty much how it looks down here in sunny Texas.

::While the dreamworks logo features a child sitting on the crescent moon as though the dark portion wasn't there, none of the versions of the logo which contain stars in the sky actually show stars 'inside' the moon's disk, so the logo probably isn't a good example of what Randall is complaining about.

The first &amp;quot;wrong&amp;quot; image is also only possible if the bright portion is presumed to be the sun during a solar eclipse, assuming the sky is actually depicted as black.

I've always wanted to create a story, and have the horns of the moon connect on the other side, so you have a blackbody in front of the moon, in parody of this tendency.&lt;br /&gt;
Also, interesting how the moon is at different rotations in different locations. I never did see the rabbit in the moon. Now I know why. [[Special:Contributions/108.162.245.74|108.162.245.74]] 04:34, 27 September 2016 (UTC)&lt;br /&gt;

Some of the examples of &amp;quot;incorrect&amp;quot; moons are kinda questionable - like, how relevant is the position of the moon when there's literally a giant divine skyperson standing on it, grabbing stars and scattering of them?

:Nope - if a distant star's light were being gravitationally lensed by the moon, then its light would appear ''adjacent'' to the moon's disk, not ''on'' it.  A star's light could only appear to originate ''on'' the moon's disk if its light were being lensed by another massive object ''between'' the earth and the moon (such as a second moon).

For the Dreamworks logo, it seems that the static versions don't sport the stars-through-the-moon problem, but I suspect the animated versions (the ones showing at the beginning of their movies) might and probably do. As it so happens, I'm watching Kung Fu Panda 2 for the first time right now, - the fishing kid is a turtle in this case, LOL! - and I note that this problem isn't present here, though there are no stars at all during the logo, so that might be the only reason why. (Of course, if a kid can sit there fishing, the rest of the moon is clearly absent, why wouldn't we see stars there, LOL!) - Niceguy1 [[Special:Contributions/108.162.218.239|108.162.218.239]] 18:40, 28 September 2016 (UTC)&lt;br /&gt;

I swear to god I've seen an Upside down moon before.... both in the day and at night the cusps were pointed down or towards the horizon heres an example of one https://www.flickr.com/photos/dcysurfer/14631243979 i'm 100% sure this is not fake and that there is no reason why one would use a dslr upsidedown or rotate it in post (this is in the southern hemisphere so that may be why... i also swear that many times i've seen the cusps pointed directly to the side (northern hemisphere)&lt;br /&gt;

Uhm, shot glasses or lemonade glasses? Does it have to be a glass or can it be a mug? Could we specify it in litres perhaps?&lt;br /&gt;
(How small a glass would you need for 5 glasses a minute in &amp;quot;normal&amp;quot; climate (20 C / 50% RH), without water poisoning? And maybe in 40 C /  15% RH?) --[[Special:Contributions/141.101.105.10|141.101.105.10]] 14:55, 18 July 2016 (UTC)&lt;br /&gt;
&lt;br /&gt;
I think that's part of the joke, which is itself about how a large amount of people have been informed you should drink x amount of glasses of water per day, but the numbers wildly vary. I'd edit that into the page, but I'm bad at formal language. --[[Special:Contributions/141.101.98.73|141.101.98.73]] 15:00, 18 July 2016 (UTC)&lt;br /&gt;
&lt;br /&gt;
It is possible to drink too much water, causing a dangerous condition called hyponatremia. Basically you end up dilluting the sodium (and other salts) in your body to a point where many normal functions can't occur. So 3000 glasses a day would probably kill you. On the other hand, I think the difference between a scientific recommendation of 5 and 8 glasses a day is statistically insignificant because other factors (height, weight, metabolism, activity levels, outside temperature, etc.) contribute much more to your needs. Bottom line, it's a lot easier to drink too little water than too much. [[Special:Contributions/173.245.56.72|173.245.56.72]] 16:02, 18 July 2016 (UTC)&lt;br /&gt;

The other 'problem' with &amp;quot;you need to drink x amount&amp;quot; of water is the the studies (citation needed) give the amount of water you should consume, which includes the water in all (nonalcoholic)* drinks and food**.  I go for days on end without drinking any plain (or carbonated) water without ill effect.  There is a reputed way to assess dyhdration which is related to the colour of your &amp;quot;water&amp;quot;.&lt;br /&gt;
(*)the diuretic effect of alcohol results in the loss of more water than it was drunk with.&lt;br /&gt;

It's my understanding that the ideal amount of water to drink is gauged by however much it takes to turn your urine clear, which would undoubtedly vary from person to person. [[Special:Contributions/173.245.50.25|173.245.50.25]] 05:35, 20 July 2016 (UTC)&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1646&lt;br /&gt;
| date      = February 22, 2016&lt;br /&gt;
| title     = Twitter Bot&lt;br /&gt;
| image     = twitter_bot.png&lt;br /&gt;
| titletext = PYTHON FLAG ENABLE THREE LAWS&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
A Twitter {{w|Internet bot|bot}} is a program that can post automatically to {{w|Twitter}}. Although Twitter bots can be very elaborate, a lot of people write simple bots for fun that simply engage in automated wordplay.&lt;br /&gt;
&lt;br /&gt;
[[Cueball]] thinks he'll write a Twitter bot, figuring out it won't be too hard. The web searches he makes tell what happens next, i.e. the bot balloons in complexity until it starts {{w|Technological singularity|following its own goals}} and Cueball no longer has any control over its actions.&lt;br /&gt;
&lt;br /&gt;
This comic examines how a seemingly simple task can often balloon in complexity if all of the requirements are not understood, while at the same time presenting the stereotypical scenario where an unassuming idea results in the accidental creation of malevolent {{w|AI}}, which then attempts to destroy humanity.&lt;br /&gt;
&lt;br /&gt;
The story, as told by the web searches, is as follows:&lt;br /&gt;
&lt;br /&gt;
*'''How to write a Twitter bot''': Cueball has no idea where to start, so he just searches for basic advice on writing generic Twitter bots.&lt;br /&gt;
*'''Python Twitter library''': The {{w|Python (programming language)|Python}} programming language has a nice {{w|Library (computing)|library}} that [https://pypi.python.org/pypi/twitter interfaces with the Twitter API]. This does all the tricky work of authenticating the bot's identity and sending the messages, so the user can concentrate on the fun parts.&lt;br /&gt;
*'''Machine learning''': {{w|Machine learning}} is the basis of {{w|Artificial intelligence|artificial intelligence}}.&lt;br /&gt;
*'''Cloud hosting''': While it's possible to host a Twitter bot on your server, you can also have it {{w|Internet hosting service|hosted}} by someone else - such as {{w|Amazon Web Services|Amazon}} - in order to take advantage of their powerful computers and robust internet connection.&lt;br /&gt;
*'''Bot troubleshooting''': Cueball is having some trouble with his bot and is looking for some information about resolving the problem.&lt;br /&gt;
*'''Locked out of EC2 instance''': {{w|Amazon Elastic Compute Cloud|EC2}} is a hosting service by Amazon that allows users to run their code in the hosting server. Cueball was running his bot from EC2, but now he's unable to access his account. He's searching for advice on how to regain access.&lt;br /&gt;
*'''Bot changed own password?''': Cueball is suspecting that the reason he can't access his Amazon EC2 account is that the bot has changed the password without Cueball's knowledge or consent. Since the bot was never programmed to change any passwords at all, the fact that it has done so is pretty scary, as one wonders what other things the bot is doing without being programmed for it.&lt;br /&gt;
*'''How to fight a bot''': Cueball is trying to physically fight the bot, but he's apparently unsuccessful and the fight results in a loud &amp;quot;boom&amp;quot; and &amp;quot;pew, pew, pew&amp;quot; sounds. The situation is scarier than before, as it starts to resemble the &amp;quot;killbot hellscape&amp;quot; in [[1613: The Three Laws of Robotics]].&lt;br /&gt;
*'''Cheap flights to Australia''': Cueball has completely given up the possibility of regaining control of the bot, so he flees to {{w|Australia}} instead. [[Randall]] lives in {{w|Massachusetts}}, USA, so Australia would be a far, far away land for him.&lt;br /&gt;
&lt;br /&gt;
In the title text the  '''Python flag enable three laws''' reference that the Python language is known for having easy constructs to perform difficult tasks (see [[353: Python]]). In this case, it is either assumed that (or Cueball is making yet another query to see if) Python has a configuration flag (i.e., a {{w|Boolean data type|boolean}} value) which, when set to &amp;quot;enabled&amp;quot; (or &amp;quot;true&amp;quot;, as opposed to &amp;quot;disabled&amp;quot;, or &amp;quot;false&amp;quot;), will cause the bot to follow {{w|Isaac Asimov}}'s famous {{w|Three Laws of Robotics}}. This is a simple enough step, and it might have been enough to prevent the &amp;quot;killbot hellscape&amp;quot; scenario, like the rule is depicted doing in the top panel of [[1613: The Three Laws of Robotics]]. It won't cause the bot to stop being in control, however, but if the bot is following the rules strictly it would not be allowed to even make Cueball uncomfortable, which he already becomes when it changes his password! It is unclear if this message is something he actually desperately tries, only searches for (like the rest of the queries) or something (someone shouts at him) that he should have done before creating the bot in the first place. Or the title text is simply Randall's comment on his own comic, like an idea to add that flag in Python. Just in case.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
&lt;br /&gt;
[[White Hat]] tries to make normal conversation with [[Cueball]] about yesterday's {{w|American football}} game, {{w|Super Bowl 50}}.&lt;br /&gt;
&lt;br /&gt;
When asking Cueball if he watched the game, Cueball begins with a simple ''Yes'', but then continues to add the contextual fact that about a third of the US population watched the event, which is an incredibly high percentage in today's [http://dictionary.reverso.net/english-definition/media%20landscape media landscape]. And according to Cueball this [http://www.hollywoodreporter.com/live-feed/tv-ratings-super-bowl-50-862888 fraction is increasing], despite [http://moneyterms.co.uk/media-fragmentation/ media fragmentation]. Thus, even though there are today more and more different ways to watch news, sports and other entertainment, the Super Bowl continues to gain more viewers every year.&lt;br /&gt;
&lt;br /&gt;
It turns out that Cueball has a problem. He cannot just reply to a simple question without trying to put the conversation into some kind of {{w|Context (language use)|context}} which does not necessarily have anything to do with the question asked, or at least not with the expected answer. From White Hat's reply it is obvious that he has had conversations like this with Cueball before, as he asks if they could ''just talk without your weird need to give context for everything?''&lt;br /&gt;
&lt;br /&gt;
Cueball feels the need to disseminate any information he finds interesting, even in trivial conversation. Normally people like to have context-free conversations and White Hat invites Cueball to try to fit in with normal people's conversational style.&lt;br /&gt;
&lt;br /&gt;
Cueball apologizes and agrees to try, but even though he really tries hard, with his fists clenched and White Hat encouraging him to just reply normally to a question about the [http://profootballtalk.nbcsports.com/2016/02/01/report-peyton-manning-has-told-close-friends-hell-retire/ rumored retirement] of {{w|Peyton Manning}}, he cannot stop himself from including context in his reply again. White Hat probably wanted Cueball to join in such minimal-context speculation. But, failing miserably again, White Hat finally gives up, and suggests they should try another conversation in a year, when Cueball might have learned to talk about the Super Bowl without context (hence the title).&lt;br /&gt;
&lt;br /&gt;
This time he goes off on a tangent about Peyton as a {{w|mammal}}, and then adding the process of {{w|aging}} and mentioning two reasons for this (which are not well understood). The first he mentions is {{w|Ageing#Damage-related factors|accumulation of damage}}, which includes {{w|mutations}} that can lead to diseases such as {{w|cancer}}. The other process he mentions is {{w|Ageing#Programmed_factors|timed factors}} which includes {{w|Telomeres}}. These have been linked to {{w|senescence|biological aging}} because of the shortening of telomeres at each {{w|Cell cycle|cell division}}; when telomeres become too short, the cells die (and so do mammals).&lt;br /&gt;
&lt;br /&gt;
To cap it off, he mentions that {{w|retiring}} is a recent concept. But this only makes sense when compared to how long there have been mammals, not compared to how long there have been sports and games, where people could be too old, and thus need to retire long before they would die from old age. Before humans began to enjoy things for fun, the concept of retiring made no sense. You worked/fought for a living, until you got too old and died.&lt;br /&gt;
&lt;br /&gt;
Cueball in this comic may represent [[Randall]], as much of {{xkcd}} is spawned from, or occasionally poking fun at, his own hyper-analytical tendencies. And it is also common knowledge that Randall is not very interested in sport, though there are several xkcd [[:Category:American football|comics about American football]]. The year before this one he made another comic in relation to the final, and in this comic, [[1480: Super Bowl]], he even mentions the fact that he does not know much about [[:Category:Sport|sports in general]]. So this is the second year in a row a comic has been released in conjunction with the Super Bowl final. But before 2015, there has only been one other comic like this, which was in 2006 with [[60: Super Bowl]].&lt;br /&gt;
&lt;br /&gt;
The title text continues the joke with Cueball replying to the old {{w|anti-humor}} joke: &amp;quot;{{w|Why did the chicken cross the road?}}&amp;quot; Cueball replies with a preposterous amount of information instead of the cliched simplistic answer: &amp;quot;To get to the other side.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Cueball begins with the origin of {{w|chickens}}. They are believed to be descendants from domestication of the {{w|Red junglefowl}}, which occurred at least five thousand years ago in Asia, as Cueball correctly explains. Before there were chickens, there could not be one crossing a road. It also couldn't be called &amp;quot;crossing the road&amp;quot; without a {{w|Road surface|pavement}}. The {{w|History_of_road_transport#Wheeled_transport|first development of paved roads}} was in the city of {{w|Ur}} in the ancient {{w|Sumer|Sumerian}} civilization about 4000 BC (6000 years ago) (also partly explained in Cueball's reply).&lt;br /&gt;
&lt;br /&gt;
As a trivial note, this comic is a rare instance of White Hat not being the fall guy for the joke. But already in his next discussion with Cueball ([[1657: Insanity]]) he was again the butt of the joke.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
[[Ponytail]] and [[Cueball]] walks in from the left to meet [[Megan]] who comes from the right. They are walking in between two trees while Ponytail tells Cueball that ''One day a year, the sun sets directly between these two trees.''&lt;br /&gt;
&lt;br /&gt;
Cueball's reply: ''Oh, cool - like the Manhattan thing'', is a reference to {{W|Manhattanhenge}}, a phenomenon occurring twice a year that causes the setting sun to align with the east-west streets of the main grid of {{w|Manhattan}}, {{W|New York City|New York}}, causing a very special light display. Manhattanhenge is itself named after {{W|Stonehenge}}, an ancient monument consisting of several large stones, where the heel stone and the embanked avenue are aligned to the sunset of the {{W|winter solstice}} and the opposing sunrise of the {{W|summer solstice}} (thus creating on purpose the effect seen today in Manhattan, on specially intended dates). Hence the title of the comic, which was released less than a week after the winter solstice which fell on 2015-12-22.&lt;br /&gt;
&lt;br /&gt;
After a beat panel Cueball, however, realizes that one could make the setting sun line up with almost any two arbitrary trees on any given day. This is due to the fact that the trees are effectively zero-dimensional points on the surface rather than one-dimensional lines like street grids. So any two trees that are close together with one tree further north would allow a setting sun to set between them; the viewer of the sunset could simply move themselves to make the alignment work. This is opposed to Stonehenge/Manhattanhenge, which requires the sun to align with a straight line, and only works on a few days a year.&lt;br /&gt;
&lt;br /&gt;
The twist comes when Ponytail and Megan actually attempt to capture the setting sun with a {{w|butterfly net}}, as it is revealed that the sun is somehow setting at the actual point between the two trees rather than behind the trees when viewed from the east side. This is of course not possible in real life, but in the comic's last panel and in the title text the girls continue with their successful though surrealistic plan.&lt;br /&gt;
&lt;br /&gt;
If this was indeed our {{w|Sun}} that they had somehow shrunk and cooled enough to captured with a butterfly net, transfer to a bag and bring it home, this would on {{xkcd}} terms be no more strange than many of the strange [[:Category:Strange powers of Beret Guy|powers]] of [[Beret Guy]]. If this would indeed happen, then since {{w|Earth}} and the rest of the {{w|solar system}} is now missing its central star there would be a ton of problems for everyone on Earth. So the girls would probably be able to get a lot of money in ransom for releasing the sun, but in the title text it turns out that they are just going to sell the Sun on-line.&lt;br /&gt;
&lt;br /&gt;
Alternatively this is not ''the'' Sun, but just a small sun-look alike, maybe a {{w|Ball lightning}} which might actually be able to behave like this (though one would not be able to capture it a bag).&lt;br /&gt;
&lt;br /&gt;
Or the girls simply play a theatrical show for the reader. They know the comic's panel orientation, reader's position and the view projection. So they position themselves like the two trees between reader and the distant sun to look like they capture it with a butterfly net and a bag.&lt;br /&gt;
&lt;br /&gt;
The title text refers to {{w|Craigslist}}, a web site where the girls plans to offer the sun for sale in hopes of getting rich. Craigslist is a {{w|classified advertisements}} website with sections devoted to jobs, housing, personals, for sale, items wanted, etc. One of the girls tells that she was uncertain as to under which category she should list a &amp;quot;Sun for sale&amp;quot;. But she put it under property (as in real estate). To advertise the &amp;quot;property&amp;quot; she put &amp;quot;''that it has 'good sun exposure''&amp;quot;, a common description of real estate. Being the sun itself you could claim that it is well located compared to the Sun, but it will never really see any sun light itself as the only &amp;quot;sun&amp;quot; light that hits the Sun is the light from other stars which is very dim.&lt;br /&gt;
&lt;br /&gt;
The title text may also be a reference to a woman who was stopped by eBay after attempting to sell plots of &amp;quot;land&amp;quot; on the Sun on the site.&lt;br /&gt;
&lt;br /&gt;
Lately [[Randall]] has had his characters catch several things (but [[:Category:Butterfly net|never butterflies]]) with a butterfly net. The next instance of butterfly nets can be seen in [[1635: Birdsong]], released less than a month after this comic's release date, wherein a bird is chased with a net.&lt;br /&gt;

&lt;div&gt;{{comic&lt;br /&gt;
| number    = 29&lt;br /&gt;
| date      = November 11, 2005&lt;br /&gt;

| image     = hitler.jpg&lt;br /&gt;
| titletext = So he's saying that God thought Hitler's art was so bad that the Holocaust was an acceptable alternative. It's no secret that the hat guy is closely based on Aram, from Men in Hats.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
[[Cueball]] speaks to an early version of [[Black Hat]] (with more of a top hat than his later &amp;quot;boater&amp;quot; hat style) about the {{w|Holocaust}} and {{w|Adolf Hitler}}. Hitler was the leader of {{w|Nazi}} Germany beginning 1933 and starting {{w|World War II}} in 1939 by attacking Poland. During that war the Germans (under Hitler's leadership) killed millions of people; most of them were Jews, but other ethnic groups, homosexuals, and the mentally disabled were all targeted as well. This has come to be known as the Holocaust.&lt;br /&gt;
 &lt;br /&gt;
Black Hat's comment that Hitler wanted to be a painter, but did not get into art school is historically accurate. He applied to the Vienna Academy of Fine Arts twice. In any event, Cueball implies in the second frame that had Hitler been accepted into art school, the course of history might have changed and the Holocaust might never have occurred. Black Hat suggests that perhaps God intentionally prevented Hitler from becoming an artist because God is an &amp;quot;art lover&amp;quot; and Hitler's art was terrible.&lt;br /&gt;
&lt;br /&gt;
As with other early comics, the title text explains the comic for us: this implies that God would have preferred the Holocaust to have occurred rather than allow Hitler to make some bad paintings. Such a comment that God could be so callous would surely be offensive to many people. Cueball's reaction to this shocking statement is relatively mild and suggests that Black Hat has made such controversial statements before. He will make a similarly controversial and Nazi-related statement again in [[984: Space Launch System]].&lt;br /&gt;
 &lt;br /&gt;
The title text also informs the reader that Black Hat is based on a character named Aram from a now-defunct comic strip entitled [http://www.meninhats.com/ ''Men in Hats'']. In the original quote when this comic were posted on [[LiveJournal]] (see [[#Trivia|Trivia]]) [[Randall]] directed the user to a specific ''Men in Hats'' comic about [http://meninhats.com/d/20040225.html parenting]. Like Black Hat, Aram seems to have frequently made judgmental, insulting or controversial comments in a very emotionless manner. Aram wore a grey (perhaps intended to be black) suit with a red bowtie and a black top hat with white strip above the brim. Black Hat's hat clearly evolved from the top hat design later in xkcd. &lt;br /&gt;
&lt;br /&gt;
This may be the comic where Black Hat truly comes into existence for the first time. He appears earlier in [[12: Poisson]], but that was actually first released more than a month later. Then there is also [[24: Godel, Escher, Kurt Halsey]], released a good month earlier. But here Black Hat does not really resemble his later appearances.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Black Hat and Cueball are talking together in the same position in all four panels.]&lt;br /&gt;
:Cueball: Learning about the Holocaust has really shaken my belief in God.&lt;br /&gt;
&lt;br /&gt;
:Black Hat: You know, as a young man, Hitler was rejected from art school.&lt;br /&gt;
:Cueball: Yeah... shame he didn't get in&lt;br /&gt;
&lt;br /&gt;
:Black Hat: Well, have you seen any of his paintings? They're &amp;lt;u&amp;gt;awful&amp;lt;/u&amp;gt;. Defy all rules of composition.&lt;br /&gt;
:Cueball: What are you suggesting?&lt;br /&gt;
&lt;br /&gt;
:Black Hat: Maybe there &amp;lt;u&amp;gt;is&amp;lt;/u&amp;gt; a god, but he's a real art lover.&lt;br /&gt;
:Cueball: This is why I don't go out in public with you.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;I disagree with the explanation (to some degree). The thing why people don't feel smug about not owning a TV is because Smart-TV is the new thing. I don't think the program has to do a lot with this trend. It's just Smart-TV is the new cool thing, yet it's still a TV. So instead of just wanting to own a TV many people go to wanting to own a big nice Smart-TV with new features and stuff. Blah!&lt;br /&gt;

If someone can find more data for television ownership I'd love to see it :) {{unsigned ip|‎173.245.54.12}}&lt;br /&gt;
&lt;br /&gt;
Can someone explain why Randall believes smugness at not owning a television is decreasing? [[Special:Contributions/199.27.128.138|199.27.128.138]] 08:31, 4 December 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
Because as TVs become less relevant, people don't feel smug for not owning one. [[Special:Contributions/141.101.99.216|141.101.99.216]] 11:44, 4 December 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
;Current explanation - logistic curve&lt;br /&gt;
&lt;br /&gt;
The current explanation is total bullshit. The thing with the negative second derivative is just saying, that the more embarrased people are, the more the change of the TV ownership rate will increase, which just means, more and more people will get themselves TVs.&lt;br /&gt;
The other point of view is, the more smug you will look like for not owning a TV, the more the change of the TV ownership rate will decline, which means, that less and less people are buying TVs.&lt;br /&gt;
&lt;br /&gt;
It has nothing to do with a logistic curve. The function, which second derivative is depicted in this comic is totally irrelevant.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
I have the strong feeling he is talking about a sine wave, not a logistic function. It fits the curve in the comic as well as the condition of f&amp;quot;=-f. &lt;br /&gt;
Also, it makes way more sense for the smugness to behave like this over time as for the first 30 years TV is culturally extremely significant and you therefore would want to own one in order to participate. But with declining quality of television and the emergence of the internet you might feel as if you were extremely progressive by not owning one anymore.&lt;br /&gt;

&lt;br /&gt;
Yes, it definitely could be a sine curve. (see: [http://www.wolframalpha.com/input/?i=d%5E2%2Fdx%5E2%28sin%28x%29%29 http://www.wolframalpha.com/input/?i=d%5E2%2Fdx%5E2%28sin%28x%29%29]). If one would neglect the beginning of the function for simplicity, this could be a solution.&lt;br /&gt;

&lt;br /&gt;
I agree with the commenter who said that the current explanation is bullshit, but I think he has the cause and effect reversed. Randall is saying that you feel more smug about not owning a TV as a result of observing how quickly TV ownership is becoming more or less trendy. In the 1950's, TV's were catching on quickly and becoming more popular, so you would feel embarrassed for not owning one. Later, the trendiness would start to decline as more people owned one, and you would head towards being smug. In the 2000s, people are giving up TVs because the internet makes them unnecessary. As this happens more and more, there's no point in feeling smug because you're no longer bucking a trend at all. --[[User:Kazim|Kazim]] ([[User talk:Kazim|talk]]) 12:49, 4 December 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
In my view the title text joke is that smugness is defined as a function of TV ownership when in reality TV ownership is a function of smugness. [[User:Ralfoide|Ralfoide]] ([[User talk:Ralfoide|talk]]) 15:18, 4 December 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
Hold on, the logistic curve gives very reasonable graphs both for ownership of TVs and for the negative second derivative. TV ownership easily fits a logistic curve, as it starts at zero and has to approach some upper limit. The negative second derivative has a very similar shape to the graph in the comic. Here's Wolfram|Alpha for the negative second derivative of a generic logistic curve: &amp;lt;http://www.wolframalpha.com/input/?i=-%28+d%2Fdx+d%2Fdx+%28100%2F%281%2Be%5E-%28.1x%29%29%29%29&amp;gt;. This would suggest that as time goes to infinity, people's feelings about TV ownership approach neutral; they do not oscillate like a sine function. This makes sense, because for the negative second derivative to be a sine function, TV ownership would have to be too, yet TV ownership is unlikely to be periodic.

&lt;br /&gt;
I have two issues with this explanation: the first is that it's too long to comfortably read, and I don't think the comic content merits such a long explanation. The other is that it reads too complexly. The point of this wiki is to make xkcd accessible for everyone, but it talks about things like sine waves, oscillation and convergence, which not all readers are going to grok. --[[User:Mynotoar|Mynotoar]] ([[User talk:Mynotoar|talk]]) 17:24, 4 December 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
If we're keeping the explanation surrounding the area of &amp;quot;People therefore discussed television programs frequently, as a major social activity.&amp;quot;, it maybe ought to be pointed out that major social discussions about TV programmes dropped off as a result of the increase in the number of TV channels and thus (except for ''particularly'' notable ratings-grabbers) the question of &amp;quot;Did you see what was on TV last night?&amp;quot; increasingly needed further qualifying.  (However, I'm not sure this is revelevant.)  Oh, and I've a feeling I should be feeling smug, right now.  Absolutely gorge myself on radio, though. [[Special:Contributions/141.101.99.229|141.101.99.229]] 21:18, 4 December 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
I do not see any evidence that this comic's title text refers in any way to a sine curve. If you consider a logistic function modeling TV ownership over time (which would look the similar to a logistic population growth model), you can take the function's second derivative, which vaguely resembles a sine curve, with the important difference that to the sides of the curve, the line becomes more level rather than repeating the curve. I would say the determining factors are the fact that the beginning of the graph is flat (as opposed to the curve just going to zero or showing the end of the previous curve), and the fact that he mentions the &amp;quot;negative second derivative of TV ownership rate,&amp;quot; and the TV ownership rate would follow a model similar to a logistic population model, which is not a sine curve, though  the second derivative of such a graph would, in fact, represent a sine curve. --[[User:Zweisteine|Zweisteine]] 21:36, 4 December 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
Not sure if I'm coming in at the end of an edit war and pouring fuel on the argument, but I think the whole smugness/TV ownership / Programming comments are well made before the last paragraph. I'm confident that Randell's title text is a superficial comment about the shape of the graph. I've edited the last paragraph so there's no mention of sine waves, oscillation, convergence, or interpretation of where the graph starts or where it's going (that seems subjective to me). Just a link to what a &amp;quot;negative second derivative&amp;quot; is, and a statement that the comic resembles that chart. [[User:XQx|XQx]] ([[User talk:XQx|talk]]) 01:02, 5 December 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
Except that graph does closely represent the second derivative graphs I've seen for graphs that start slow, rise suddenly, then level out again, like a population chart, or a chart showing TV ownership over time. [[User:Zweisteine|Zweisteine]] ([[User talk:Zweisteine|talk]]) 01:18, 5 December 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
I think that, theoretically, something closer to an arctangent fits the number of televisions over time graph better than a logarithmic curve- at least if we consider some of the thousands of years during which nobody owned televisions. Linked below is a plot of arctan(x-2) + 1.3 and its negative second derivative (scaled to fit better in WolframAlpha's output window), the latter of which looks as much like the smugness graph in the comic as anything I've seen so far.&lt;br /&gt;
http://www.wolframalpha.com/input/?i=plot+atan%28x-2%29+%2B+1.3%2C+6%28x-2%29%2F%28x^2-4+x%2B5%29^2+for+x+%3D+0..4&lt;br /&gt;

&lt;br /&gt;
While the previous explanation of the title text involving the sine function was bogus (it's the second derivative of TV ownership rate, not the second derivative of smugness), the stuff about logistic (or arctangent or other sigmoid) functions is correct (if you believe that TV ownership should follow a sigmoid curve).  I think that this can be explained, so I've put that in; hopefully, one can read it without the parentheses to get something understandable to lay folk, and then the parentheses show where Randall's mathematical jargon comes in.  —[[User:TobyBartels|TobyBartels]] ([[User talk:TobyBartels|talk]]) 04:59, 5 December 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
The &amp;quot;this is incomplete because it needs further information&amp;quot; is not much of an explanation of what needs to be completed. It looks like the tag was added when the explanation was really, really poor and it't now obsolete. I would update it if I could figure out something that is still missing, but at this moment it looks like removing it altogether could be a better option.

&lt;br /&gt;
One obvious problem with the data is that one does not maintain a level of smugness and thus the chart dips eventually, as in the graph (but to an unknown extent).&lt;br /&gt;
The problem is that you don't know the rate of &amp;quot;getting over yourself&amp;quot;. Without a TV to remind you that you don't have a TV, you stop feeling smug by getting on with your life. The idea of not having a TV then becomes a different problem if when in conversation you tell anyone that you don't have a TV. This very seldom happens and has its own emotional curves.I used Google News BEFORE it was clickbait 07:36, 10 January 2015 (UTC)&lt;br /&gt;

:As a fellow Britisher, similarly not paying for (or needing!) a TV Licence, I think this might need explaining to the furriners here.  There are different payment methods (&amp;lt;strike&amp;gt;up to&amp;lt;/strike&amp;gt; down to, and including, purely commercial channels, but also the same cable/satelite subscriptions as we might ''also'' have to make) supporting TV channels, elsewhere.

;Sigmoid function or Sine curve&lt;br /&gt;
&lt;br /&gt;
I'm sorry, but the {{w|Sigmoid function}} doesn't fit the graph. A sine looks much more closer but in fact it is some like f(x) + g(x), the second part looks much more like a sine (but also not accurate) while the first part looks different. And only the second derivative on this graph is important. So g(x) looks similar to a sine and the second derivative shows just an inverted plot, that's the point. There is no real math function.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 20:39, 5 December 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
:Back-tracing the provided graph, the (negative) second derivative is clearly near zero up until nearly 1950, declines to a minima around 1965 (it appears to be around 40 pixels per decade, along the scale) before crossing the zero mark at 1980 to a maxima around 2001/2002-ish, then falling again.&lt;br /&gt;
:Thus the (positive) first derivative (with an unknown constant of offset) is near horizontal until the 1950s, rises to its steepest in 1965 (i.e. the acceleration in rate of growth is the highest... consistent the uptake of the 'new' technology being popular), continues upwards but finally hits a maxima (in actual rate of growth of TV ownership) in 1980, before tailing off (probably still a rate of ''increase'', but near saturation level.  Just after the millenium is around the time I'd expect to see a rise in Large Screen TVs being sold (plasma TVs were late '90s, and we're starting to see proper flatscreen LCDs and, later, OLED versions).&lt;br /&gt;
:So, can we relate that to the 'zeroeth' derivative?  (i.e. The actual rate of TV ownership... or is it sales..?  May be both if you allow for multi-TV homes.)  Starting at zero ownership, there was a slow uptake around the 1950s (for the UK, 1953 - the year of the Coronation - was supposed to be the start of the mass-market TV revolution, but perhaps only around one house a street actually ''getting'' a TV for the event...  still, it'd somewhat match the quick start of the (negative) curve in the cartoon).  The mid 1960s was (amongst other things) the height of the Space Race, and thus in the white-heat of that particular phase of technology.  By the 1980s, most existing households without TVs weren't ''going'' to get them, so uptake would have flattened from that point onwards, until eventually the millenium came about and newer/additional sets were installed in houses during that particular credit-boom and period of techno-consumerism.&lt;br /&gt;
:IIW, I think it matches a (convoluted, multi-inflected) S-curve from zero on upwards.  Possibly beyond 100% if multi-TV ownership counts to technically allow the original curve to strike up above that value.  I may have zero TVs operating in my house but most families I know have at ''least'' two of them. [[Special:Contributions/141.101.99.229|141.101.99.229]] 02:05, 6 December 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
As you (Dgbrt) say, the sine curve doesn't fit the beginning (and it would require TV ownership rate to also fit a sine curve, which is implausible).  But the sigmoid curve fits it fine!  People above have posted some negative second derivatives of sigmoid curves, and they match the graph.

::The main point of this seems to be smugness being relative to how odd you are compared to the average.  The problem here is the oddness is by choice or simply you can't afford one in the early days.  The difference towards the more modern era will be that people will feel smug for not having a TV, but may also feel smug for owning way above average many TVs.  Other options also should have altered the graph, such as multi-function TV/Monitors(which I'm using mostly for a monitor and occasionally as a TV for science documentary) and smart phones/tablets which got TV functions, on the other hand, people may own a TV as part of a home entertainment system, which means what is showed in the channels is completely irrelavent.  The increase of options has reduced the smugness for not owning one, because there are so many things with a TV function and so many things a TV can do, not owning one means that you are almost technologically isolated, which most would feel embarassed.

Check for blindness or hallucination:&lt;br /&gt;
&lt;br /&gt;
* Do you agree that Randall's graph looks more or less like the 7 graphs that I linked above, especially the first few?  (Same basic shape.)&lt;br /&gt;
&lt;br /&gt;
* Do you agree that Wolfram Alpha produced those graphs after I properly asked it about the negative second derivatives of various functions?  (Check for words &amp;quot;second derivative&amp;quot; and minus sign.)&lt;br /&gt;
&lt;br /&gt;
* Do you agree that these functions are all listed on the Wikipedia page about sigmoid curves?  (Graph 0 matches the formula for a logistic function, multiplied by 4 to put it on the same scale as the others; graphs 1 through 6 have the same formula as the graph on Wikipedia comparing six sigmoid curves.)&lt;br /&gt;
&lt;br /&gt;
If you can see all of this, then you are not blind or hallucinating.&lt;br /&gt;
&lt;br /&gt;
Nota bene: nobody is claiming that Randall's graph is itself a sigmoid curve.  It is the negative second derivative of a sigmoid curve.  This is what it should be, since Randall conjectures that it's the negative second derivative of the TV ownership rate, and the TV ownership rate should follow a sigmoid curve.&lt;br /&gt;

I think that the new explanation for the title text, while somewhat accurate is a bit overcomplex.&lt;br /&gt;
&lt;br /&gt;
1. There is probably a simpler way to explain what a second derivative is (not necessarily diffently described; it's just a bit jumbled up in the description).&lt;br /&gt;
&lt;br /&gt;
2. For the purposes of explanation, I doubt that so much detail is needed, especially because the real-life meaningfulness of the second derivative of TV ownership doesn't seem like much at all.&lt;br /&gt;
&lt;br /&gt;
I would suggest something like this, but with a bit more depth: The title text sugests that smugness and the second derivative of TV ownership are related. The derivative of a graph is its rate of change at any given point, and the second derivative is the rate of change in the first derivative.

==Explanation==&lt;br /&gt;
[[Cueball]] wants to say ''ri-fucking-diculous'', but he inserts the ''fucking'' too late in the word. Now, he has to say ''ridicu-fucking-lous'', which sounds ri-fucking-diculous.&lt;br /&gt;
&lt;br /&gt;
This is an example of {{w|tmesis}}, the breaking up of a word to include another within it, and more specifically of {{w|expletive infixation}}. Normally, for rhythmic reasons the included word is inserted before the {{w|Stress (linguistics)|stressed}} syllable (''ri'''dic'''ulous'' becoming ''ri-fucking-'''dic'''ulous'') which is what Cueball messed up. However, in some cases it is also possible to break the word after a prefix instead, so for some words there are two ways to do it e.g. {{w|wikt:unbefuckinglievable|unbe-fucking-'''lie'''vable}} (before the stressed syllable) or {{w|wikt:unfuckingbelievable|un-fucking-be'''lie'''vable}}; this is because ''unbelievable'' is a combination of ''un'' and ''believable'' to negate ''believable'' which is an actual English word and therefore it still sounds good.&lt;br /&gt;
&lt;br /&gt;
The [[title text]] introduces a further example, with speaker inserting the ''fucking'' too late into the word ''absolutely''—which would have resulted in ''absolute-fucking-ly''—but leaving the word unfinished when they realize their mistake. The more usual tmesis here would be {{w|wikt:absofuckinglutely|''abso-fucking-lutely''}}.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:Cueball: Man, that is '''''ridicu'''''-fucking—... ...Hang on, I inserted &amp;quot;fucking&amp;quot; too late and now there's just one awkward syllable left. Can I back up?&lt;br /&gt;

:I'm all for information freedom, but you CAN steal fire. You could take away the only spark/source of ignition/activation energy provision in the possession of the gods. Secondly, fire needs fuel to burn. Take away all their fuel, and you've stolen their fire. Alright, you have your own fuel? Fine, you're still stealing fire, because once you've discovered how to make a fire - you burn your fuel, release more combustible products, and choke the atmosphere (Though, we'd have snuffed ourselves out before we snuffed out Olympus). In any case, you're accelerating the {{w|heat death}} of the universe, and making all thermodynamic cycles &amp;quot;less efficient&amp;quot; because of the higher sink temperatures. But that's not the marrow of the bone of contention. Even the original Prometheus-v-Gods animosity arose because of information theft, and not 'property' theft.

:I'm all for information freedom, but you CAN steal fire. You could take away the only spark/source of ignition/activation energy provision in the possession of the gods. Secondly, fire needs fuel to burn. Take away all their fuel, and you've stolen their fire. Alright, you have your own fuel? Fine, you're still stealing fire, because once you've discovered how to make a fire - you burn your fuel, release more combustible products, and choke the atmosphere (Though, we'd have snuffed ourselves out before we snuffed out Olympus). In any case, you're accelerating the {{w|heat death}} of the universe, and making all thermodynamic cycles &amp;quot;less efficient&amp;quot; because of the higher sink temperatures. But that's not the marrow of the bone of contention. Even the original Prometheus-v-Gods animosity arose because of information theft, and not 'property' theft.

:: You CAN steal fire, but looking at the {{w|Prometheus}} myth it doesn't seem gods lost the fire after the &amp;quot;theft&amp;quot;. Would be pretty hard, too, considering the gods ({{w|Hephaestus}} specifically) have {{w|volcano}}s (which, technically, are powered by geothermal energy and not by burning fuel ; speaking about them, igniting wood using volcanos can easily be a source of Prometheus myth).

&lt;div&gt;Here is the truth: Enough wind turbines over time will kill us all. The wind turbines slow down Earth's rotation. Whit that the trade winds will die and then there would be no life possible on Earth. Maybe and only maybe we already slowed down Earth enough to induce a climatic change (so many strange natural disasters the last few years ...) and we will face a real-life &amp;quot;The Day After Tomorrow&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
Perhaps his motivation is to restore natural wind patterns to the environment. I remember reading about the ecological impact of wind power includes lessened wind currents. Some organisms rely on the wind to propagate the species, such as winds that blow seeds or how some spiders &amp;quot;parachute&amp;quot; on wind currents.

&lt;br /&gt;
Um, wind turbines have an electric motor which is computer-controlled, and which I think isn't completely powered by the blades rotating (if only that, when the wind is still, the turbine stops spinning, and needs a boost to start again when the wind picks up, similar to a car battery and starter motor). If the power was cut (which wouldn't happen, BTW. Wind farmers aren't stupid and they realise the problems with normal cables, so it's all underground), the turbine would slow down and stop, like a solar-powered pinwheel. {{unsigned ip|108.162.250.223}}&lt;br /&gt;

&lt;div&gt;I'm saying this is a bad idea for a fridge. Don't mistake me, I'm an xkcd-fan just like you. But Randall obviously has never seen a full fridge. I mean &amp;quot;full&amp;quot; like packed full with no space for fresh food. That here only works for empty/medium filled refrigerator. And that would be a waste of energy, see sustainable etc. (I have my fridge currently offline). Besides that doesn't solve the more urgent problem in most households: the freezer compartment, which is almost always full. But yeah, I know, this is just for fun.&lt;br /&gt;

&lt;br /&gt;
I thought an alternative design for the fridge could be to have the middle conveyor belt attached to the right, leaving a gap on its left and obviously it would move toward the left. This way we could put food on the topmost belt on its left side and the food would travel along that belt then drop onto the middle one, then travel to the bottom belt and finally fall into the BAD bin. Of course we'd have to relabel all belts accordingly. [[User:DelendaEst|DelendaEst]] ([[User talk:DelendaEst|talk]]) 12:27, 17 September 2012 (UTC)&lt;br /&gt;

&lt;br /&gt;
::I disagree. I'm with DelendaEst. I presume the premise is that you initially place the food at the appropriate place. Milk might start at the 2-week mark on the shelf, whereas juice might start at the 4 week mark, and ketchup might start at the many month mark. Randall has designed it so you put the food on the relevant shelf. In the left-right-left right scenario, the top shelf might run 3 months to 1 month, and take two months to roll from left to right. Then the second shelf could be 1 month to 1 week, and take approximately 3 weeks to roll from right to left. The bottom shelf would take 1 week to roll from left to right into the &amp;quot;bad&amp;quot; bin. You would just have to put stuff down based on initial expiration date. Ketchup might go on the top-left, while milk might go in the middle of the second shelf, etc. In Randall's version, the food at &amp;quot;2 days&amp;quot; on the top shelf, the second shelf and the door shelf should all reach the bad bin at the same time.

Sorry Randall: so much for brilliant... there's a bug in your design.  Look at the top rack in the door.  There is a chute that would prevent food from falling past when the door is closed.

::I think the anon user is pointing out that the little &amp;quot;ramp&amp;quot; below the door belt would actually roll food into the side wall of the fridge when the door is closed. The ramp should be oriented from the wall of the door towards the back of the fridge (when the door is closed) instead of towards the side wall. so the food rolls from the door back into the fridge and the &amp;quot;bad&amp;quot; bin, rather than rolling into the side wall of the fridge.

The fridge is designed so that the &amp;quot;BAD&amp;quot; bin is as long as the width of the body shelves plus the width of the door shelves. That way, the food from the top shelf of the door will fall between the middle/bottom shelves and the side wall, and into the front end of the &amp;quot;BAD&amp;quot; bin.

The problem I see is that you would have to place the food back exactly where you took it from, or a little to the right. It still works, but you would have to be very precise. Maybe keep some markers to put on the conveyor belt to mark where the food came from.

&lt;div&gt;Just FYI: Mac is a subset of PC. And the more I observe the fight of Linux vs. Windows the more I think Linux users aren't very smart. I love programming but I dislike Linux and stuff.&lt;br /&gt;
&lt;br /&gt;

Should there be some added discussion of the fact that a Mac (or a Linux machine, or other OS) is a &amp;quot;personal computer&amp;quot;, and by definition a PC? {{unsigned ip|72.45.165.98}}&lt;br /&gt;

:It's sad that kids today don't remember the fact that PC was, for ages, a branded term for a Microsoft computer specifically to distinguish them from filthy Macs.

::The term {{w|Personal computer}} (PC) became popular after IBM introduced its {{w|IBM Personal Computer}} in 1981, even when the name was used also before. Microsoft never did brand that name but they bought some software licences to create {{w|MS-DOS}}. Apple, together with others, did sell graphical user interfaces long before Microsoft did. The big success of Microsoft only belongs to the decision by IBM allowing other companies to build {{w|IBM PC compatible|IBM compatible}} computers. The success is only caused by cheaper hardware.

I would question whether &amp;quot;since most everything nowadays is done through browsers '''due to the proliferation of cloud computing'''&amp;quot; is true. While I would suspect that the first half of the sentence is largely true, is cloud computing specifically really that prevalent? My take on the comic was that using a browser to access the web is such a major part of the everyday use, that the 'other' use is minimal (and hence PC vs Mac is of limited relevance). --[[User:Pudder|Pudder]] ([[User talk:Pudder|talk]]) 11:24, 12 September 2014 (UTC)&lt;br /&gt;
: And why is web browsing such a major part? Well, at least partly because fewer and fewer installs software for e.g. e-mail handling, picture and movie organizing, document creation... Instead we have Gmail, Flickr, Youtube, Google Docs, and so on. Cloud services, that is.

&lt;div&gt;How does the mimic octopus manage to mimic multiple fish? Does it split it's own body up or something?

:&amp;quot;When under attack, some octopuses can perform arm autotomy, in a similar manner to the way skinks and other lizards detach their tails. The crawling arm serves as a distraction to would-be predators. Such severed arms remain sensitive to stimuli and move away from unpleasant sensations.[23]&amp;quot;[http://en.wikipedia.org/wiki/Octopus#Defense] {{unsigned ip|173.245.48.113}}&lt;br /&gt;
::Fine, but in the SCUBA diver depiction, would it really need to rip parts out of itself to mimic bubbles? I don't think that that is quite necessary. {{unsigned ip|108.162.241.131}}&lt;br /&gt;
:::It could also hypothetically mimic bubbles by *actually blowing bubbles*. (No word on how it does this.) [[Special:Contributions/108.162.216.30|108.162.216.30]] 02:36, 2 January 2016 (UTC)Anon&lt;br /&gt;
::::Simple: This is a 2D {{w|Tomography|cut-out}} of the octopus mimicking the fishes or the scuba '''in 3D'''. It assumes a very complex figure, so that in the cut-out we only see the 2D pictures above.&lt;br /&gt;
&lt;br /&gt;
For the record, octopus is from the Greek ὀκτάπους, a compound of ὀκτά (eight) and πούς (foot); πούς is a third declension masculine noun, whose plural is πόδες. Therefore, the etymologically correct plural of octopus should be octopodes, not (as Orson Scott Card suggests) octopoda, since πούς is not a neuter.&lt;br /&gt;
:Actually, it would be &amp;quot;octopuses&amp;quot;, as it showed up ''after'' the regularization of English plurals to a final -s. As the video in the explanation explains, someone in the Victorian Grammarian Era &amp;quot;realized&amp;quot; it was &amp;quot;Latin&amp;quot; and pluralized it as such. This caught on and still haunts us to this day. &amp;quot;Octopdes&amp;quot; was coined around the same time by a more observant someone, who realized it was actually Greek. Personally, I avoid the whole trichotomy by saying &amp;quot;octopods&amp;quot;. Unrelated etymologically, but has the same meaning and is unequivocally regular.

&lt;div&gt;Maybe just the geek talking here, but what's with 5x5 Rubik's cube? It should be called 5x5x5 Rubik's cube. Ok, in the title text that might be a 2-dimensions-joke. But see the previous comments. Do the readers and &amp;quot;explainers&amp;quot; all think only 2-dimensional?&lt;br /&gt;
&lt;br /&gt;
2x2 rubik's cubes are harder. Just sayin'. '''[[User:Davidy22|&amp;lt;u&amp;gt;{{Color|#707|David}}&amp;lt;font color=#070 size=3&amp;gt;y&amp;lt;/font&amp;gt;&amp;lt;/u&amp;gt;&amp;lt;font color=#508 size=4&amp;gt;²²&amp;lt;/font&amp;gt;]]'''[[User talk:Davidy22|&amp;lt;tt&amp;gt;[talk]&amp;lt;/tt&amp;gt;]] 01:25, 17 April 2013 (UTC)&lt;br /&gt;
: What? A 2x2 is often solved in under two seconds at competitions. The world record for 5x5 is [https://www.worldcubeassociation.org/results/regions.php 48.42 seconds]. See also below. [[User:Mumiemonstret|Mumiemonstret]] ([[User talk:Mumiemonstret|talk]]) 12:26, 12 December 2014 (UTC)&lt;br /&gt;

This would likely be found in the residence of my colleague ['''REDACTED'''], as he has a collection of odd Rubik's Cube clones.{{unsigned|173.72.159.14}}&lt;br /&gt;
&lt;br /&gt;
I solve the cube with corner pieces and edge pieces in separate steps, so I find 2x2s harder. I just have to do the corner steps. 04:25, 23 June 2013 (UTC){{unsigned|184.11.73.88}}&lt;br /&gt;
&lt;br /&gt;
2x2s are certainly not harder than any other Rubik's cube by ANY standard. As the corners of any Rubik's cube have the same rotational moves, you have to solve a 2x2 at some point when solving any cube. 4x4 is harder than 5x5 though, because you can rotate away the middle pieces.[[Special:Contributions/85.164.251.29|85.164.251.29]] 07:11, 29 August 2013 (UTC)&lt;br /&gt;
: Looking at [https://www.worldcubeassociation.org/results/regions.php speedcuber's results] I would disagree. 4x4 takes less than half the time. But you have a point since the &amp;quot;general geek&amp;quot; targeted by this comic's scheme might find it easier to deduce the function of a 5x5 due to the centerpieces. I still think you'd need to be a brilliant geek to be able to solve a 5x5 without prior knowledge.

The current incomplete tag asks why voice 1 calls Joe Biden &amp;quot;the man&amp;quot; and voice 2 calls him J.B. As far as I can see, there is no deeper/cryptic meaning to the choice of these words, other than possible space saving. Both 'J.B.' and 'the man' are shorter than 'Joe Biden'.

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic is a reference to IBM's computer {{w|Watson (computer)|Watson}} that beat humans at {{w|Jeopardy}} (see [[1002: Game AIs]]). The IBM team created a computer that could formulate a response to a Jeopardy-style question. In case you are not familiar, Jeopardy is a game played where the contestants are given the answer to a question, and must devise the question. A question might be &amp;quot;Its largest airport was named for a World War II hero; its second largest, for a World War II battle&amp;quot;, to which the contestant must answer &amp;quot;What is Chicago?&amp;quot;. When going up against two Jeopardy champions, Watson was able to {{w|Watson_(computer)#Jeopardy.21|beat them both}} (by some margin, although he did answer the above mentioned question incorrectly with &amp;quot;Toronto&amp;quot;).&lt;br /&gt;
&lt;br /&gt;
[[Megan]] chimes in that we are &amp;quot;pretty awesome at teaching&amp;quot; which is very true. Humans are the best (on this planet) at teaching other things to do a set of tasks. We train dogs, cats, lizards, birds, other people, and now we are getting quite good at ''teaching'' a computer, a simple machine completely of our own design, to mimic our own thought patterns and make decisions similar to what we would make. (See also [[1263: Reassuring]]).&lt;br /&gt;
&lt;br /&gt;
The title text makes fun of teaching our children values about not trying to win by any means (i.e. but while playing fair) by suggesting we are just trying to hold on to our ability to beat them in something.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;

:Cueball: Wow — researchers taught a computer to beat the world's best humans at yet ''another'' task. Does our species have ''anything'' left to be proud of?&lt;br /&gt;
:Megan: Well, it sounds like we're pretty awesome at teaching.&lt;br /&gt;
