{{w|Cicada|Cicadas}} are a species of insect whose nymphs burrow underground and emerge as adults to reproduce several years later.  One common species in North America is the 17-year cicada, also known as the {{w|periodical cicada}}.  These cicadas form distinct {{w|Periodical_cicadas#Map_of_brood_locations|broods}} which burrow and emerge as a group every 17 years, with different broods starting the cycle at different times.  This results in a couple of weeks every 17 years when the cicadas swarm in huge numbers, then vanish just as quickly when the adults die off.  Cicadas also make a distinctive buzzing sound, which makes their periodic appearance even more memorable.&lt;br /&gt;
&lt;br /&gt;
In the comic, [[Cueball]] and [[Ponytail]] have accidentally created 17-''second'' cicadas using {{w|genetic engineering}}.  This means that rather than seeing a massive swarm every 17 years, they have to deal with a swarm every 17 seconds.  This makes it very difficult for them to do their work, especially to figure out how the cicadas were created, because the swarm keeps interrupting their work.&lt;br /&gt;

		<summary type="html">&lt;p&gt;172.69.22.218: /* Explanation */&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1164&lt;br /&gt;
| date      = January 23, 2013&lt;br /&gt;
| title     = Home Alone&lt;br /&gt;
| image     = home alone.png&lt;br /&gt;
| titletext = Starring Macaulay Culkin.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
''{{w|Home Alone}}'' is a popular 1990 film in which the child protagonist Kevin McCallister (portrayed by {{w|Macaulay Culkin}}) is accidentally left alone in his house when his family goes on vacation, and has to thwart a burglary all by himself. In the movie, McCallister comes up with a variety of ingenious traps and schemes (usually involving {{w|jury rig|jury-rigged}} toys and household items) to harass, injure and eventually incapacitate the burglars, which was the film's defining feature. On a more general level, the films revolve around the classical trope with an [http://tvtropes.org/pmwiki/pmwiki.php/Main/UnderdogsNeverLose underdog defeating a much stronger opponent] (the burglars), through his own ingenuity. The film spawned a {{w|Home Alone (franchise)|series of sequels}} (4 as of 2012, the first of which also starred Culkin) all with a similar premise to the original.&lt;br /&gt;
&lt;br /&gt;
This strip, however, proposes a {{w|Reboot_(fiction)#Film|reboot}} of the franchise, with the main change to the film being that of an age-reversal, so the story is now about an adult man setting needlessly harmful traps to hurt defenseless children breaking into his house. This would likely be seen as distasteful at the very least, and would probably lead to a negative reputation for the film. The title text adds another punchline when it is revealed that the reboot also stars Macaulay Culkin in the same role. This may suggest that the age-reversal gimmick was done to allow for him to star in the film as the same character despite growing up since the beginning of the franchise. This would be a rather misguided attempt to revive his career, and would probably just prevent any further success.&lt;br /&gt;
&lt;br /&gt;
The scene depicted in the strip is an adaptation of an iconic scene from the first movie (used heavily in advertising) where McCallister hangs two paint cans in strings above the staircase, and let them swing down to hit the burglars in the face.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a DARK MATTER SQUIRREL ON A SPINNING BIRD FEEDER. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
In this comic, [[Megan]] and [[Cueball]] are talking about {{w|dark matter}}. Megan states that dark matter's density across the solar system is 0.3&amp;amp;nbsp;GeV/cm&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;, as claimed by, for example, [https://arxiv.org/abs/1205.4033 Bovy and Tremaine (2012) &amp;quot;On the local dark matter density&amp;quot; in ''Astrophysics of Galaxies''.] Since Cueball likely does not have a science background, he does not understand what this means, so, to clarify, Megan explains that 0.3&amp;amp;nbsp;GeV/cm&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; equates to one squirrel's worth of dark matter for the volume of the Earth. For the last two panels, Cueball conflates this with dark matter actually ''being'' a squirrel for comedic effect, enraging Megan.&lt;br /&gt;
&lt;br /&gt;
The {{w|gigaelectronvolt}} (GeV) is a unit of energy that can be converted to a mass using {{w|Mass%E2%80%93energy_equivalence|Einstein's formula}} ''E'' = ''mc''&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;. It is typically used for subatomic particles, such as {{w|weakly interacting massive particles}} (WIMPs), one of {{w|Dark matter#Composition of dark matter: baryonic vs. nonbaryonic|several contending possibilities}} for the still-open question of the composition of dark matter, and the one which Megan's uniform density figure assumes constitutes most of it. For example, the mass of a proton is 0.938&amp;amp;nbsp;GeV/''c''&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;. However it is frequent to omit the ''c''&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; factor and to represent masses in GeV (or MeV).

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a DARK MATTER SQUIRREL ON A SPINNING BIRD FEEDER. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
In this comic, [[Megan]] and [[Cueball]] are talking about {{w|dark matter}}. Megan states that dark matter's density across the solar system is 0.3&amp;amp;nbsp;GeV/cm&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;, as claimed by, for example, [https://arxiv.org/abs/1205.4033 Bovy and Tremaine (2012) &amp;quot;On the local dark matter density&amp;quot; in ''Astrophysics of Galaxies''.] Since Cueball likely does not have a science background, he does not understand what this means, so, to clarify, Megan explains that 0.3&amp;amp;nbsp;GeV/cm&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; equates to one squirrel's worth of dark matter for the volume of the Earth. For the last two panels, Cueball conflates this with dark matter actually ''being'' a squirrel for comedic effect, enraging Megan.&lt;br /&gt;
&lt;br /&gt;
The {{w|gigaelectronvolt}} (GeV) is a unit of energy that can be converted to a mass using {{w|Mass%E2%80%93energy_equivalence|Einstein's formula}} ''E'' = ''mc''&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;. It is typically used for subatomic particles, such as {{w|weakly interacting massive particles}} (WIMPs), one of {{w|Dark matter#Composition of dark matter: baryonic vs. nonbaryonic|several contending possibilities}} for the still-open question of the composition of dark matter, and the one which Megan's uniform density figure assumes constitutes most of it. For example, the mass of a proton is 0.938&amp;amp;nbsp;GeV/''c''&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;. However it is frequent to omit the ''c''&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; factor and to represent masses in GeV (or MeV). A mass represented as 0.3 GeV is equal to 5.35&amp;amp;nbsp;×&amp;amp;nbsp;10&amp;lt;sup&amp;gt;&amp;amp;minus;25&amp;lt;/sup&amp;gt; grams [https://www.wolframalpha.com/input/?i=0.3+(GeV%2Fc%5E2)+in+grams]. This implies a {{w|squirrel}} has a mass of 580&amp;amp;nbsp;g [https://www.wolframalpha.com/input/?i=(0.3+(GeV%2Fc%5E2)%2Fcm%5E3)+*+(volume+of+earth)+in+grams] (about 1.3&amp;amp;nbsp;lb), which is a typical mass among several species of common squirrels.&lt;br /&gt;
&lt;br /&gt;
The title text imagines using a spinning bird feeder like a {{w|particle accelerator}}, colliding hydrogen atoms at relativistic speeds to detect new and exciting particles like the {{w|Higgs boson}}. Note, however, that accelerating even [https://what-if.xkcd.com/1/ one squirrel] to relativistic velocities would destroy the feeder and be deadly to any birds near the feeder (not to mention the squirrel).&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by UNUSUAL MEANS. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
The comic is a special Disappearing comic that was placed before the normal Monday comic update, which is [[2185|Cumulonimbus]]. The entire comic is an advertisement for [[Randall|Randall's]] upcoming book &amp;quot;[[How To]]&amp;quot;. &lt;br /&gt;
It was, of course, released on [[:Category:Sunday comics|a Sunday]] (August 4th), becoming only the fifth comic to be released on a Sunday. It is also the first comic that was fully deleted from the xkcd archives, as it was replaced by the normal update. &lt;br /&gt;
&lt;br /&gt;
The entire comic is a link directly to https://xkcd.com/how-to/. This link is also mentioned in the text of the comic. But as Randall has never learned to make different part of an image into a link the other link mentioned in the text, to his [[Blag]] is not linked from the comic. The link to this is https://blog.xkcd.com/. At the moment of this comics release the top blog post is the one about How To book.&lt;br /&gt;
&lt;br /&gt;
The first part of the comic, the advertisement, includes a drawing of the cover, two sets of pages, showing the open book, and a sampling of the table of contents of the book. The full table of contest can be found in the Blag post mentioned above.&lt;br /&gt;
&lt;br /&gt;
The second part of the comic, the joke, apologizes for various bots that automatically catalog xkcd comics that might break because of this special comic. See more under [[#Unusual Means|Unusual Means]]. This website is one example assigning the comic a number of 2185 despite the comic not having a designated number.  The comic even broke the xkcd site itself as the previous comic (2184) had a next button that links to comic 2185 (which does not exist) and displays a [[404]] error (but this was later fixed by giving this comic number 2185, see the [[#Trivia|Trivia]] section, if nothing else then until it disappears!)&lt;br /&gt;
&lt;br /&gt;
One of the bot methods mentioned may be in reference to the recent comic [[2180: Spreadsheets]], where [[Cueball]] debates making a real program to do a task, or to use a Google spreadsheet instead.&lt;br /&gt;
&lt;br /&gt;
In the title text it is stated that: ''This comic won't exist in the archives. NOTHING IS REAL.''. However, as shown in the [[#Trivia|Trivia]] section, Randall had so many problems with his plans for this comic, that he ended up making it a normal numbered comic and thus also put it into the archives, although it was later removed.&lt;br /&gt;
&lt;br /&gt;
==Unusual Means==&lt;br /&gt;
Randall notes that ''if you read xkcd through unusual means... ... I hope this ephemeral ghost comic doesn't break them too badly''&lt;br /&gt;
&lt;br /&gt;
Between the dots he suggested different methods of reading xkcd, other than on the {{xkcd}} home page. These methods get progressively sillier (many still need explanations). Here is a list:&lt;br /&gt;
&lt;br /&gt;
; Apps&lt;br /&gt;
: The Android app [https://play.google.com/store/apps/details?id=de.tap.easy_xkcd easyxkcd] was broken by this comic when used in offline mode, as reported [https://github.com/tom-anders/Easy_xkcd/issues/162 here].&lt;br /&gt;
; Custom screen-scraping systems&lt;br /&gt;
: See https://en.wikipedia.org/wiki/Data_scraping#Screen_scraping&lt;br /&gt;
; Google Reader clones&lt;br /&gt;
: [https://en.wikipedia.org/wiki/Google_Reader Google Reader] was an RSS/Atom aggregator that Google discontinued in 2013. Enthusiasts created a full-featured work-alike replacement, called [https://theoldreader.com/ The Old Reader.]&lt;br /&gt;
; Twitter bots&lt;br /&gt;
: Automated posting to [https://twitter.com/ Twitter]&lt;br /&gt;
; BASH scripts&lt;br /&gt;
: A popular Un*x shell; one might, say, write a script in it to run on one's personal Un*x machine, checking for a new xkcd comic and displaying it somewhere&lt;br /&gt;
; Gopher portals&lt;br /&gt;
: [https://www.minnpost.com/business/2016/08/rise-and-fall-gopher-protocol/ Gopher] was a method of surfing the Internet that predated the Web (by about five months) and was vastly more popular (for about three years)&lt;br /&gt;
; Lynx-based ASCII art browsers&lt;br /&gt;
: [https://en.wikipedia.org/wiki/Lynx_%28web_browser%29 Lynx] is a text-based Web browser. It can launch external programs to view images, but Randall is suggesting that instead a Lynx variant might convert images to [https://www.asciiart.eu/ ASCII art], which renders images using the 94 visible ASCII keyboard characters&lt;br /&gt;
; Third-party Second Life feeds&lt;br /&gt;
: [https://secondlife.com/ Second Life] is a virtual world that opened in 2002 and has [http://www.gridsurvey.com/charts/historicalconcurrency.png averaged about 40,000 simultaneous users for the past five years.]&lt;br /&gt;
; RFC 2549&lt;br /&gt;
: An RFC is a proposal for how to run the Internet. [https://tools.ietf.org/html/rfc2549 RFC 2549] is about transmitting data using carrier pigeons (this was one of the earliest [https://en.wikipedia.org/wiki/April_Fools%27_Day April Fools' Day] RFCs).&lt;br /&gt;
; Massive Google docs sheets&lt;br /&gt;
: See #[[2180]].&lt;br /&gt;
&lt;br /&gt;
Another unusual method is [http://uni.xkcd.com/ UNIXkcd], which was reported here to have broken, but was later working.&lt;br /&gt;

On the book cover, in white drawings, are seen Ponytail with a ladder and either Black or White Hat (hard to say on black background). Both are looking up on Cueball who is floating in the air with a quadcopter beneath either leg, trying to plug in an electric light bulb in a naked lamp hanging down near him. It seems he has already removed the broken light bulb, as he has one in both hands. And now he tries to put in the new one. He could have let Ponytail use the ladder...]&lt;br /&gt;

:[Below the text with the arrow to the book is the following text with an arrow pointing down to an image of two pages in the open book, shown to the right:] &lt;br /&gt;
:And the inside looks like this.&lt;br /&gt;
&lt;br /&gt;
:[To the left of the open book are the following text:]&lt;br /&gt;
:Chapters include:&lt;br /&gt;
:'''How to charge your phone'''&lt;br /&gt;

:'''How to move'''&lt;br /&gt;
:'''How to build a lava moat'''&lt;br /&gt;
:'''How to ski'''&lt;br /&gt;
&lt;br /&gt;
:[The open book to the right has almost only unreadable text. The left page shows a drawing of car in front of a trailer which is loaded with about 15 of boxes in four layers. Two stick figures are standing between the car and the trailer, talking with each other. The trailer is not attached to the car. There are some lines of text beneath the drawing and then what appears to be a chapter heading. It probably says something as &amp;quot;How to move&amp;quot;, as this is mentioned as a chapter in the text to the left of these pages, but there one of two more unreadable words at the end of that heading. Beneath that the rest of the page is text and at the bottom there seems to be a footnote. The right page shows a house that seems to be floating a couple of meters above the ground, two arrows pointing up to the bottom of the house on either side. A stick figure stands to the left of the house which float at the figures head height. There is text beneath this drawing. Beneath that there is another drawing of a house towed on a truck, which speeds up a steep hill and jumps over a cliff to get to the other side. Seems like it will work. The speed of the truck seems to be very high as indicated by two curly lines indicating exhaust from the truck. It becomes three small clouds further behind the moving house. There is a footnote beneath the drawing. The driver of the truck yells as the truck jumps. This can actually be read:]&lt;br /&gt;
:Driver: ''Woooooo''&lt;br /&gt;
&lt;br /&gt;
:[Beneath the above text and pages are another image of the open book with two other pages. This time to the left. This time there is text to the right.]&lt;br /&gt;
&lt;br /&gt;
:[These book pages are also mainly unreadable. At the top of the left page is a drawing of what could be a lake. Two people seems to be standing out in the water, only heads showing above the water. A sign is standing on the brink, is may say &amp;quot;Sorry&amp;quot;? Behind the lake is some mountains in the background. Beneath the drawing is some text of, then a smaller diagram like drawing which may show some black clouds above and below a line in the middle of this drawing. One of the clouds are beneath a curly bracket which are beneath the line. The curly bracket lies down and has the same length as the cloud. Beneath this drawing is more text and then a third drawing at the bottom. Here is shown a cross section of the lake. At the left side of the lake the water is shallow and a stick figure is standing in the water on the bottom, head above water with its arms held up in the air. It is directing its attention to the four stick figure standing on the brink to the left looking at the figure in the water. To the right the lake becomes more than three times as deep. Clouds are above the lake, one large just right of the stick figure and one smaller further right. At the right edge the lakes edge is vertical. On the brink is what may be a diving board protruding over the lake. Something is lying on top of the board. And above is what seems to be another cloud. To the right of the lake is a pile of earth with what appears to be a large black Nuclear bomb (with the nuclear icon on it) stuck with its tip in the pile. On the right page is a line coming down from the top, which then turns to the right ending in an arrow. There is a line of text above the horizontal part of the line. The arrow points to a large heading in two rows. (See below). Beneath the heading are a few lines of text. Then a drawing of a torn map (like an old treasure map whit a X at the end of a trail marked with dots. Mountains indicated with small &amp;quot;^&amp;quot; and coast line is visible. There seems to be text beneath the X. There are text beneath the drawing. Beneath that are a header with a line beneath it, and then text beneath the line.]&lt;br /&gt;
:How to Dig a Hole&lt;br /&gt;
&lt;br /&gt;
:[To the right of these pages are the following text:]&lt;br /&gt;
:You can learn more and preorder it at '''xkcd.com/how-to'''&lt;br /&gt;
:And read an excerpt at '''blog.xkcd.com'''&lt;br /&gt;
&lt;br /&gt;
:[Beneath all this Randall (drawn as Cueball) is telling about the problem this disappearing comic may cause:]&lt;br /&gt;
:Randall: If you read xkcd through unusual means, including apps, custom screen-scraping systems, Google reader clones, Twitter bots, bash scripts, gopher portals, lynx-based ASCII art browsers, third-party Second Life feeds, RFC 2549, or massive google docs sheets full of =IMPORTHTML() and =IMAGE() formulas, I hope this ephemeral ghost comic doesn't break them too badly. &lt;br /&gt;
:Randall: It will disappear with the normal Monday update.&lt;br /&gt;
:Randall: (At least, I think it will. I've never tried this before. So I'm honestly not sure what the server will do.)&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
*This August 4th 2019 [[:Category:Sunday comics|Sunday comic]] was first posted on the front page without any number relating to it. Thus breaking the next comic button on xkcd. &lt;br /&gt;
**Since it is supposed to be deleted on Monday August 5th 2019, when the next comic arrives on xkcd, it was not supposed to have a number or be in the archive. But seems like this caused too many problems for the xkcd site it self (not just for all the other sites Randall jokes about). So later it was given the next number in the comic list (2185) and was also included in the archive, although it was later removed from the archive and 2185 was assigned to the Monday comic.&lt;br /&gt;
*Here are some pictures documenting that the comic at some point between release and the next comics release worked like a normal comic with number 2185 as shown in the web address at the top. (The question is if the next comic will be 2185 and this will disappear?):&lt;br /&gt;
*[[File:Disappearing Sunday Update with number 2185.png]]&lt;br /&gt;
*It was also part of the archive with the release date shownig when hovering over the title:&lt;br /&gt;

It would sound more natural if it were &amp;quot;''SMFW '''as''' an acronym almost makes sense''&amp;quot;.  Is the fact that &amp;quot;as&amp;quot; was omitted from that sentence supposed to give us a hint as to what &amp;quot;SMFW&amp;quot; might mean?

: Yeah, &amp;quot;as&amp;quot; is ommitted because its meaning is contained within the mystery acronym, so for example &amp;quot;W&amp;quot; may be &amp;quot;When&amp;quot;.

| titletext = My brother once asked me if there was a function to produce a calendar grid from a list of dates in Google Sheets. I replied with a single-cell formula that took in a list of dates and outputted a calendar. It used SEQUENCE(), REGEXMATCH(), and a double-nested ARRAYFORMULA(), and it locked up the browser for 15 seconds every time it ran. I think he learned a lot about asking me things.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a REGEXREPLACE(). Need to explain the Google Sheets fucntions. Do NOT delete this tag too soon.}}&lt;br /&gt;
[[Cueball]] is doing some task on his computer, with an {{w|Shoulder angel|angel and devil on both sides of him}}, trying to influence his work. The angel is telling him to do things the &amp;quot;right&amp;quot; way, while the devil is telling him to do his work using a {{w|spreadsheet}}, which is considered by professional software engineers to be a shortcut or a hack.{{Citation needed}} &lt;br /&gt;
&lt;br /&gt;
Spreadsheets provide an array of cells, which can contain information or instructions.  Spreadsheets are a common {{w|end-user development}} tool, allowing non-developers to easily create code.  However they can be hard to maintain, thus they are often mocked by developers as a wrong approach to programming. Although it is not clear from the cartoon that this is meant, the &amp;quot;right&amp;quot; alternative to using a spreadsheet for some task may involve a database or a more general programming language.&lt;br /&gt;
&lt;br /&gt;
The punch line comes when the angel becomes so intrigued by the spreadsheet functions, Google Sheets in particular, that it gives up trying to dissuade Cueball, and asks for more information from the devil.&lt;br /&gt;
&lt;br /&gt;
In the title text, Randall mentions a time when he created a calendar grid in Google Sheets using a list of dates. This is described as being done in a &amp;quot;single-cell formula&amp;quot;, and taking a long time to run. This shows the power and complexity of spreadsheets.  The procedure taking a long time to run, and freezing up the computer for 15 seconds every time it ran, was probably not what Randall's brother had in mind when he requested help.  His brother learned he might need to be wary about what he gets back when asking Randall for assistance.&lt;br /&gt;
&lt;br /&gt;
All functions mentioned in this comic can be found in {{w|Google Sheets}}, but functions similar to some of them can be found in most modern spreadsheet applications.&lt;br /&gt;

| titletext = My brother once asked me if there was a function to produce a calendar grid from a list of dates in Google Sheets. I replied with a single-cell formula that took in a list of dates and outputted a calendar. It used SEQUENCE(), REGEXMATCH(), and a double-nested ARRAYFORMULA(), and it locked up the browser for 15 seconds every time it ran. I think he learned a lot about asking me things.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a REGEXREPLACE(). Need to explain the Google Sheets fucntions. Do NOT delete this tag too soon.}}&lt;br /&gt;
[[Cueball]] is doing some task on his computer, with an {{w|Shoulder angel|angel and devil on both sides of him}}, trying to influence his work. The angel is telling him to do things the &amp;quot;right&amp;quot; way, while the devil is telling him to do his work using a {{w|spreadsheet}}, which is considered by professional software engineers to be a shortcut or a hack.{{citation needed}} &lt;br /&gt;
&lt;br /&gt;
Spreadsheets provide an array of cells, which can contain information or instructions.  Spreadsheets are a common {{w|end-user development}} tool, allowing non-developers to easily create code.  However they can be hard to maintain, thus they are often mocked by developers as a wrong approach to programming. Although it is not clear from the cartoon that this is meant, the &amp;quot;right&amp;quot; alternative to using a spreadsheet for some task may involve a database or a more general programming language.&lt;br /&gt;
&lt;br /&gt;
The punch line comes when the angel becomes so intrigued by the spreadsheet functions, Google Sheets in particular, that it gives up trying to dissuade Cueball, and asks for more information from the devil.&lt;br /&gt;
&lt;br /&gt;
In the title text, Randall mentions a time when he created a calendar grid in Google Sheets using a list of dates. This is described as being done in a &amp;quot;single-cell formula&amp;quot;, and taking a long time to run. This shows the power and complexity of spreadsheets.  The procedure taking a long time to run, and freezing up the computer for 15 seconds every time it ran, was probably not what Randall's brother had in mind when he requested help.  His brother learned he might need to be wary about what he gets back when asking Randall for assistance.&lt;br /&gt;
&lt;br /&gt;
All functions mentioned in this comic can be found in {{w|Google Sheets}}, but functions similar to some of them can be found in most modern spreadsheet applications.&lt;br /&gt;

&lt;br /&gt;
== Transcript ==&lt;br /&gt;
&lt;br /&gt;
I tried to start one, but it's going to be hard to do the list of warnings right.--[[Special:Contributions/108.162.215.190|108.162.215.190]] 00:33, 23 July 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Well I've gone ahead and added all the warnings that I could. The only way to know the ones that are just &amp;quot;Advisory&amp;quot;, &amp;quot;Watch&amp;quot;, or &amp;quot;Warning&amp;quot; on the left hand side is if we talk to Randall himself. --[[Special:Contributions/172.68.46.113|172.68.46.113]] 00:50, 23 July 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
All NWS statements are color coded and the few that I know off the top of my head (Severe T-Storm, Hurricane) seem to match with Randall's coloring. Idk who filled out the transcript of warnings and if they already did this, but if everything thing else we know marches, we could use that to determine the remaining one.&lt;br /&gt;
&lt;br /&gt;
Also on a separate note, Gale Warning is listed twice. Once in the top left in full and again along the right side where it's cut off as &amp;quot;Gale War&amp;quot;. [[Special:Contributions/162.158.126.76|162.158.126.76]] 01:57, 23 July 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
Went through the [https://www.weather.gov/help-map NWS List of Warnings] and updated all the cut off warnings as accurately as I could, I'm not sure about the Severe Weather Statement, the color is rather close to Rip Current Statement too. [[User:Multiverse|Multiverse]] ([[User talk:Multiverse|talk]]) 03:05, 23 July 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
OT: When I first read the Blizzard Warning in the south-east, I thought it was a Buzzard Warning; I think that is not on the NWS list of warnings, alerts and advisories.  It seems like pretty much everything is there except an Amber Alert, but that is handled by other agencies. [[User:Nutster|Nutster]] ([[User talk:Nutster|talk]]) 03:26, 23 July 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
Maybe we should add colors of the warnings to the transcript, but there seems to be so many colors and shades and my command of English color adjectives is not adequate. -- [[User:Malgond|Malgond]] ([[User talk:Malgond|talk]]) 07:38, 23 July 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
== Gale War ==&lt;br /&gt;
Ok, so it's possibly Gale Warning; but a war between the North Wind and Dorothy in Oz would be something worth warning about surely? [[User:Kev|Kev]] ([[User talk:Kev|talk]]) 01:11, 23 July 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
== Weather for the past week ==&lt;br /&gt;
&lt;br /&gt;
~~There was a flash flood watch near maryland, would that relate?~~&lt;br /&gt;
:A massive heat wave affected a large portion of the USA this past weekend. I'm willing to bet that was the inspiration for this comic. https://twitter.com/NWS/status/1152708819291688960 [[Special:Contributions/108.162.241.124|108.162.241.124]] 11:57, 23 July 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
== What's the pun? ==&lt;br /&gt;
&lt;br /&gt;
I don't think the real (or the only) pun is in NWS having to go on vacation sometimes. I feel (but I am not a U.S. resident) that the comic refers to NWS or any other agency issuing too many or too broad warnings, making them somewhat useless and annoying. That's my impression regarding my own country's alerting system at least. The comic, in usual Randall's style, just takes it to the extreme, vacation being only an excuse. Any comments from U.S. residents regarding real-life alerts? -- [[User:Malgond|Malgond]] ([[User talk:Malgond|talk]]) 07:49, 23 July 2019 (UTC)&lt;br /&gt;
:I think the cartoon is illustrating that too many warnings is a bad thing.  You have similar problems with computers and airlines (where once the pilots removed wiring to stop the constant unnecessary warnings).  Warnings tend to be additive through mission creep and contradictory, meaning too much noise and not enough signal getting through to the end user who lacks the cognitive load to make appropriate actions. [[User:Kev|Kev]] ([[User talk:Kev|talk]]) 09:37, 23 July 2019 (UTC)&lt;br /&gt;
::I agree, the cartoon probably is playing off of the extreme number of weather warnings issued these days. I think I've gotten &amp;quot;extreme heat&amp;quot; warnings for the past week straight, and I can't remember the last time I went a week without some kind of extreme weather warning, like a thunderstorm, fog, heat, cold, ... you know, normal things.[[Special:Contributions/162.158.126.34|162.158.126.34]] 11:23, 23 July 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
What a good day to live in East North Carolina. And pleasant weather for anyone who happens to be searching for the Red October!&lt;/div&gt;</summary>
