==Explanation==
{{incomplete|Created by HERMAN MILLER. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}

[[Beret Guy]] informs [[Cueball]] that he purchased a cursed office chair from a mysterious shop. Cueball isn't sure if he remembers this happening, which is possibly because Beret Guy has [[1772: Startup Opportunity|previously stated]] that he makes a habit of purchasing daily necessities from such stores. Beret Guy then exclaims that the store he bought the chair from was gone when he went to return it, though given his buying preferences, he should perhaps not be so surprised{{Citation needed}}. Cueball suggests that maybe the shop was simply closed due to the {{w|COVID-19 pandemic}}, as is the case for wide variety of non-cursed businesses {{Citation needed}}. Beret Guy takes this as proof that the chair somehow caused the pandemic, a claim Cueball meets incredulously. In the final panel, Beret Guy is doing battle with the chair, which taunts him and claims to be immortal ("''I cannot die''"). In fact, most{{Citation needed}} chairs cannot die, because they are not alive {{Citation needed}}. Cueball remarks that it would be simpler to shop at {{w|IKEA}}, a store famous for its minimalist flat-pack furniture, and which does not sell cursed items{{Citation needed}} (although they ''do'' sell "[[2024: Light Hacks|miniature Dyson spheres]]").

The cursed chair and the boarded-up store are references to the stores that sell cursed items mentioned in [[1772: Startup Opportunity]]. In that comic, the stores vanished without a trace, so the fact the door was boarded is much more likely due to the pandemic or other causes than the store mysteriously disappearing.

Buying an item from a shop you never noticed before, bringing it home, discovering it is cursed, and trying to return it only to discover the shop isn't there anymore is a popular trope. See {{tvtropes|TheLittleShopThatWasntThereYesterday}}.

In the title text, the {{w|Siege Perilous}} is the empty seat at the Round Table in Arthurian legend, reserved by Merlin for the knight who would find the {{w|Holy Grail}} (who turns out to be Sir {{w|Galahad}}) and fatal to anyone else who sits in it. {{w|Herman Miller (manufacturer)|Herman Miller}} is an American office furniture company that produced the {{w|Aeron chair}}, which is the basis for [https://www.instagram.com/blantonmuseum/p/BCYaKA4GLrg/ an artwork] by {{w|Glenn Kaino}} called ''The Siege Perilous''. {{w|Wirecutter (website)|''Wirecutter''}} is a website that evaluates and recommends consumer products. From the title text, it sounds like (in the xkcd universe) Wirecutter is used to encountering cursed products, so they didn't even bother trying to sit in it to test the Siege Perilous's perilousness (er, ''peril'') before they started fighting it -- and emerged victorious, if it's {{tvtropes|OnlyMostlyDead|only ''nearly'' as immortal}} as it boasts.

2319: Large Number Formats

2020-06-15T04:43:42Z

162.158.63.238: /* Explanation */

{{comic
| number = 2319
| date = June 12, 2020
| title = Large Number Formats
| image = large number formats-2.png
| titletext = 10^13.4024: A person who has come back to numbers after a journey deep into some random theoretical field
}}

==Explanation==
{{incomplete|Created by ABRAHAM LINCOLN. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}
This comic shows what the way you write large numbers says about you. Different people use different methods to express large numbers. And this comic claims it can tell something about you based on the way you format large numbers. In this way, the comic is similar in idea to [[977: Map Projections]], where it was your choice of map projections that could tell something about you.

See the [[#Table of types|table]] below for each of the 10 different ways to express large numbers, plus the 11th mentioned in the title text.

The number used as an example is the [https://www.wolframalpha.com/input/?i=Distance+to+Jupiter+in+inches approximate distance] from the planet {{w|Earth}} to the planet {{w|Jupiter}} as of the release day of the comic on June 12th 2020, in {{w|inch|inches}} (1 inch = 2.54 cm).

Two days after the release of the comic the following text could be found on [https://theskylive.com/jupiter-info Jupiter info] on [https://theskylive.com/ The Sky Live].
:The distance of Jupiter from Earth is currently 640,084,108 kilometers, equivalent to 4.278698 Astronomical Units. Light takes 35 minutes and 35.0908 seconds to travel from Jupiter and arrive on Earth.

64,008,410,800,000 cm / 2.54 inches/cm = 25,200,161,732,283 inches - much less than the number used in the comic. But Jupiter's distance to Earth changes quite quickly, and was decreasing at the time of the release of the comic.

According to a graph of the distance as a function of time on The Sky Live, the distance on the release day was 643,1 million km. This will give 25,313 which the used number will round to.

The used number 25,259,974,097,204 is equivalent to 641,6 million km. On June 13th the distance is given as 641,7 million km in the graph on The Sky Live, very close to the number used. As this was the day after the release of this comic, it seems like [[Randall]] used a different distance than the exact one for the release day. He may have also used an average for June which would be 642 million km based on the average of the distance on June and July 1st.

==Table of types==
{| class="wikitable"
|-
! Number
! Type of person
! Notes
|-
| 25,259,974,097,204
| Normal Person
| This is the full number, 25259974097204, written out in the normal fashion, with commas to indicate powers of 1000. Although writing out the number in full is indeed a common action for normal people, the specific comma convention depicted here is only considered normal in the Anglo-Saxon world; conventions for writing large numbers in full vary considerably across cultures. For example, in countries where the comma is used as a {{w|decimal separator}} (including Europe outside the UK), one would write the number as 25.259.974.097.204 (or 25'259'974'097'204 in Switzerland, or 25 259 974 097 204 in Poland, France and Estonia). Under the {{w|Indian numbering system}}, this number would be written as 25,25,997,40,97,204.
|-
| 25 Trillion
| Normal Person
| This is the number, rounded to trillions in the normal fashion.
|-
| 25 Billion
| Old British Person
| In current English usage, across the Anglophonic world with some hold-outs, an n-illion means 10^(3n+3) as per the {{w|short scale}} system popularised by American influence in international trade, so a trillion means 10^12, as above. However, older British English use had an n-illion meaning 10^(6n) (i.e. the simpler calculation of ''million^n''), so a billion meant 10^12. The change stems from a 1974 commitment by Harold Wilson, the Prime Minister of the UK at the time, to change from the {{w|long scale}} (previously often described as the British system) to the short one for all official purposes.

Though not instantly widely adopted for common usage, the mid-'70s could therefore be considered the key turning point between when an older or younger British person learns (as the change filters through the system at various stages of education) what their "Billion"s and "Trillion"s are supposed to represent.

As well as 'traditionalist' British use, the long scale is widely used in the non-Anglophone world, in local language versions, though while the British system tended to infill n-and-a-half powers of the million with the term "thousand n-illion", the suffix "-illi''ard''", or equivalent, is often used for the thousands multiple directly atop the respective "-illion" point.
|-
|2.526x1013
|Scientist
|This number is formatted in {{w|scientific notation}}, using the exponent 1013.
|-
| 2.525997x1013
| Scientist trying to avoid rounding up
| Using as many decimal places as necessary until hitting a digit (0-4) that results in rounding down, even if it goes against the common scientific practice of reporting the correct amount of "significant figures". [[:File:large number formats.png|A previous version of the comic]] had a typo (the number was ''2.5997x1013''), but Randall updated the comic.
|-
| 2.526e13 or
2.526*10^13
| Software developer
| The first example is how the number would be expressed as a floating point number in scientific notation in [https://rosettacode.org/wiki/Literals/Floating_point every common programming language]. The second example is a technically correct way of expressing the same thing in some programming languages in which exponentiation is indicated by the ^ operator. However writing it that way instead of the first way would be considered quirky, as it is written as an instruction to the computer to calculate the product of a number with 10 raised to power 13, instead of just writing the number. A software developer might write it that way if they are a novice who is not familiar with the first notation. Or they could have an unusual personal preference that considers the second version easier to read. Perhaps the joke for the second version is that it is the standard scientific notation with the x for multiplication and superscript for raising to a power replaced with the notation used in many programming languages of * and ^, i.e., a software developer writing down a number in scientific notation, not necessarily while writing a program, would by habit write a * for multiplication and a ^ for exponentiation.
|-
| 25,259,973,541,888
| Software developer who forgot about floats
| The two most common computer {{w|Floating-point arithmetic|floating-point}} formats are the IEEE 754 {{w|Single-precision floating-point format|single-precision}} and {{w|Double-precision floating-point format|double-precision}} representations. These are ''binary'' floating-point formats, representing numbers as the quantity ''a'' × 2''e'', for some fractional number ''a'' and exponent ''e''. Both the values ''a'' and ''e'' have a fixed size in bits, and therefore a finite range. In single-precision, ''a'' and ''e'' have (effectively) 24 and 8 bits, respectively, while in double precision the effective sizes are 53 and 11 bits.

Fully representing the number 25,259,974,097,204 (in any format) requires at least 45 bits. Therefore this number cannot be represented exactly as a single-precision float. The closest possible representations are 0.717931628 × 245 and 0.717931688 × 245; these work out to 25,259,973,541,888 and 25,259,975,639,040, respectively. Of these, the one ending in 888 is considerably closer to the original, so is chosen due to {{w|rounding}}. (Naturally these numbers are represented internally in binary, not decimal; the actual representations, in hexadecimal, are <tt>0x0.b7ca5e</tt> × 2<tt></tt>0x2d and <tt>0x0.b7ca5f</tt> × 2<tt></tt>0x2d.)

In many programming languages, the keyword to request a single-precision floating-point variable is <tt>float</tt>, while the keyword to request double-precision is <tt>double</tt>. It is an easy mistake to make to forget about the limited precision available with type <tt>float</tt>, especially since its name sounds like what you want for "floating point". (Had the programmer remembered to use type <tt>double</tt>, the number 25,259,974,097,204 could have been represented exactly, as <tt>0x0.b7ca5e43c9a000</tt> × 2<tt></tt>0x2d.)
|-
| 1013
| Astronomer
| For extremely large distances, astronomers typically only care about orders of magnitude, e.g. whether a number is 1013, as opposed to 1012 or 1014. Randall often jokes about the lack of precision needed by astronomers, such as in [[2205: Types of Approximation]] where the astronomer-cosmologist is equally willing to make pi equal to one, or ten. The original number is rounded to the nearest power of ten.
|-
| {∅,{∅},{∅,{∅}},{∅,{∅},{...
| Set theorist
| In {{w|Zermelo–Fraenkel set theory}}, the natural numbers are defined recursively by letting 0 = ∅ (the {{w|empty set}}), and ''n'' + 1 = ''n'' ∪ {''n''}. So, every natural number ''n'' is the set of all natural numbers less than ''n'', and since 0 is defined as the empty set, all numbers are nested sets of empty sets. Note that writing out the full number in this fashion would take more than its square in number of characters; that is to say, if each character took up one square inch, this "number" would not fit on a square piece of paper whose edge reached to Jupiter.
|-
| 1,262,998,704,860 score and four
| Abraham Lincoln
| In the {{W|Gettysburg Address}}, Lincoln speaks the number "87" as "four score and seven" ("score" meaning "20"). Base-20 or {{w|vigesimal}} numeral systems are or have been used in pre-Columbian-American, African and many other cultures. In French it is used only for higher numbers (e.g. 92 = quatre-vingt-douze). In English it can appear in certain archaic and classic contexts, such as the King James translation of the Bible ("threescore years and ten" to be the life expectancy of a human according to Psalm 90:10). In these cases, a number is written in "score" (multiples of 20) plus a remainder. In this case 1,262,998,704,860 * 20 + 4 yields the exact number.
|-
| 10^13.4024 ''(title text)''
| A person who has come back to numbers after a journey deep into some random theoretical field
| In some fields of mathematics, especially those dealing with very {{w|large numbers}}, numbers are sometimes represented by raising ten (or some other convenient base) to an oddly precise power, to facilitate comparison of their magnitudes without filling up pages upon pages of digits. An example of this is {{w|Skewes's number}}, which is formally calculated to be ''e''''e''''e''79, but is more commonly approximated as 10101034. 13.4024 is a rounded version of the {{w|common logarithm}} of 25,259,974,097,204 (log10 25,259,974,097,204 = 13.4024329009); thus, this "format" is still mathematically correct, but uncommon. However, only by using many more digits will the result get close enough to be rounded to the original number 10^13,40243290087302 = 25,259,974,097,203.5, which would round up to the correct number. This number 10^13.4024 = 25,258,060,548,319.6 deviating almost 2 billion from the correct number

Um, I take it that whoever explained this comic can't tell the difference between < and >, as the fact that the confidence was changed wasn't mentioned in the article... [[Special:Contributions/76.246.37.141|76.246.37.141]] 23:19, 20 September 2013 (UTC)
:Yes, I also figured out this today, green is lower than 0.05, on other colors there is just a confidence that it's NOT lower than 0.05. The newspaper did add this remaining 19 panels to 95%. The article is marked as incomplete, it needs a major rewrite.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 19:12, 3 October 2013 (UTC)

This explanation seems to misinterpret α. α is the chance of rejecting a true null hypothesis, a false positive. The 5% here is α. The correct interpretation of it is that if the null hypothesis is true, there is a 5% chance that we will mistakenly reject it. P in "P<0.05" is the chance that, if the null hypothesis is true, a result as extreme as, or more extreme than, the result we get from this experiment. '''α is not the chance that, given our current data, the null hypothsis is true. We wish to know what that is, but we do not know.'''[[Special:Contributions/108.162.215.72|108.162.215.72]] 08:52, 16 May 2014 (UTC)

In layman's terms, the comic appears to misrepresent what "95% confidence" (p <0.05) means. The statistic "p < 0.05" means that when we find a correlation based on data, that correlation will be a false positive fewer than 5 percent of the time. In other words, when we observe the correlation in the data, that correlation actually exists in the real world at least 19 out of 20 times. It '''does not''' mean that 1 out of every 20 tests will produce a false positive. This comic displays a pretty significant failure in understanding of Bayesian mathematics. The 5% chance isn't a 5% chance that any test will produce a (false) positive; it's a 5% chance that a statistical positive is a false positive. {{unsigned ip|108.162.219.196}}

:No, you are deeply mistaken. The comic and the comment above you are correct in saying that if the null hypothesis holds, 1 out of every 20 tests will produce a false positive: this is by definition of the p-value. The ratio of true positives to false positives can range anywhere from 0 to infinity, and there is unfortunately no way to predict it. [[Special:Contributions/108.162.229.121|108.162.229.121]] 09:46, 27 January 2015 (UTC)

The explanation appears somewhat confused, as correctly noted in a couple of comments above. The most common misunderstanding of p-values is that they represent how likely it is that the observed correlation (or observed unequal outcomes, or apparent trend) came from chance. That is not what they represent - they represent the probability that results at least as extreme as those observed would have arisen by chance: 1) in a fictional world where chance was the only potential cause of the correlation/inequality/trend (a world in which the null hypothesis was true) AND 2) only one hypothesis was being tested. In the real world, other factors may be more or less plausible as explanations, and it takes judgement, not stats, to determine how likely it is that chance is the best explanation. The green jelly beans theory fails in terms of biological plausibility, so it is >99% likely to be a chance observation (regardless of the p-value). Also, given the large number of hypotheses being tested, the probability of at least one of them producing a p-value <0.05 is much greater than 5%; indeed, with 20 simultaneous hypotheses, we would expect about one to be significant at the p<0.05 level, on average. There is a huge difference between the prospective probability of a single hypothesis satisfying the p<0.05 threshold, and the probability of being able to find a retrospective hypothesis for which p<0.05. This is a case of post hoc cherry picking - the newspaper's emphasis on green jellybeans is post hoc, with the colour of interest chosen after the results were already in. {{unsigned ip|108.162.250.163}}

Is the "e" in "News" supposed to look like an epsilon (and the "w" a rotated epsilon)? [[Special:Contributions/108.162.250.222|108.162.250.222]] 15:00, 15 December 2014 (UTC)
:It's probably just a stylistic thing. [[User:GrandPiano|GrandPiano]] ([[User talk:GrandPiano|talk]]) 04:00, 28 January 2015 (UTC)

In the comic, they mention that there is a link between green jelly beans and acne. However, assuming there to be no real link, there is 50% chance that this link was caused by 95% confidence that green jelly beans help with acne.[[User:Mulan15262|Mulan15262]] ([[User talk:Mulan15262|talk]]) 03:14, 12 November 2015 (UTC)

One thing I've gleaned from this is that they apparently opened a bag of Jelly Bellys or Gimball's and tested them in whatever order. I say this because they hit colors you'd never see in the smaller-palette brands of jelly beans (brown, teal, salmon) before some very common colors (red, yellow, black, green). If it were me, I would probably have started with a smaller-palette brand, since their colors affect ''everyone'' who eats jelly beans, and not just the ones who go for the gourmet brands.

162.158.63.238:

Unless you want to go completely nuts on this topic, avoid reading Jane Austen, where the the term "X-in-law" is used to mean, roughly, "someone to whom you are related for legal reasons". It can be used to refer to, for example, what we today might refer to as step/half-siblings, adopted siblings, etc. [[User:Arcanechili|Arcanechili]] ([[User talk:Arcanechili|talk]]) 15:51, 31 August 2018 (UTC)

> The title text refers to incestual relationships, which are generally frowned upon in Western culture.
How on earth this refers to incest if persons are only legally, not genetically related??? It's just that Randall doesn't know how to call new relatives but cannot stop their arrival. {{unsigned ip|162.158.91.251}}

Yes, I also don't think it refers to incest. {{unsigned ip|172.68.94.40}}

:I'm not sure if that is right or not, but that was my interpretation of that text, based on the "a reason why these two should not be wed." Unless there is a different issue with this, also involving marriage? [[Special:Contributions/162.158.59.190|162.158.59.190]] 16:44, 31 August 2018 (UTC)

::I read the title text as... the reason he is objecting has nothing to do with the couple getting married, it's simply the selfish reason that Randall doesn't want the confusion of having to figure out what to call the new extended-family members.

^ Sspenser I honestly think this is a poorly constructed diagram because it invites this type of confusion -- I was also tripped up at first, but I think all relationships are meant to be labeled *with respect to "Me"/cueball*. My initial assumption was that each double-headed arrow was intending to label *pairs* of siblings-in-law; in fact I think it is trying to label individuals who are each independently siblings-in-law of cueball's (or assumed siblings-in-law of cueball's). The different double-headed arrows represent different levels of confidence in claiming this relationship between Cueball and the individuals in that "layer." I think it would have been more clear if he kept the arrows basically the same, but labeled as "*My* Siblings-in-law"/"Also *My* Siblings-in-law, I think?"/etc. ~clukes [[Special:Contributions/162.158.63.238|162.158.63.238]] 00:28, 1 September 2018 (UTC)

The Russian language actually has different words for both "types" of brothers in-law (spouse's brother vs. sister's husband), also for parents and children in-law on either side: https://ru.wikipedia.org/wiki/Свойство_(родство) .
But all these in-law distinctions are based on the respective spouse's sex, so it won't work for same-sex marriages. {{unsigned ip|162.158.234.58}}

:In German, they even have a word for "spouse of sibling in-law" and similar situations: "Schwippschwager" https://de.wikipedia.org/wiki/Schwippschwager [[User:Polyfier|Polyfier]] ([[User talk:Polyfier|talk]]) 23:41, 31 August 2018 (UTC)

The way this is defined, you and your spouse both have the same set of siblings and siblings-in-law. In other words, if someone is your spouse's sibling or sibling in law then that person is your sibling in law if that person is not your sibling. The relationship chains across a maximum of one sibling relationship.

Off topic but I can't resist:

Anyone else think this comic is a form of "Wedding Gift" Randal is giving to a sibling who's getting married (presumably today)?

People actually complain cousins removed is hard to understand? When I first learned about it, my thought was actually: Wow, that is so much clearer than what we use in Dutch. In Dutch we use a prefix for each step its is removed so it can get wordy. A cousin would be "neef" a cousin once removed would be "achterneef" a 2nd cousin "achterachterneef". I think a 2nd cousin removed would then be "achterachterachterneef" and third cousins "achterachterachterachterneef". I'm not even sure that's how confusing it is. The English system is easy. Simply count up to the common ancestor (A), then down to the relative (R). Then you're (R-2)th cousins (A-R) times removed. Fun fact, your siblings are your zeroth cousins and you are your own negative first cousin. [[User:Tharkon|Tharkon]] ([[User talk:Tharkon|talk]]) 22:32, 31 August 2018 (UTC)

Talk:2037: Supreme Court Bracket

162.158.63.238: I have no idea what I'm doing with this comment.

Came here for insight, only to discover this is tomorrow's comic, I'm viewing Friday's comic on Thursday after midnight. D'oh! Damn, seeing a comic early and I can't provide or contribute to the explanation, LOL! I realize the bracket and "Sweet 16" are sports things, I think football and/or basketball, and I spotted the famous name Roe vs. Wade, so seems like court cases, but that's it. Looking forward to people explaining the smaller jokes (I spotted "Loving" and "Virginia", and I feel like I recall their license plates say "Virginia Is For Lovers" I think, I expect something there).

Errm. You can go back to the previous comic if you hit the [<Prev] button just above the current one. {{unsigned ip|141.101.107.36}}

I agree that this is a sports reference, but can someone also include some sort of note about the title? I think that the "Supreme COURT" is referring to a basketball COURT, connected to how brackets like this are used in basketball like with March Madness. [[User:B. A. Beder|B. A. Beder]] ([[User talk:B. A. Beder|talk]]) 05:50, 24 August 2018 (UTC)
:No, I'm pretty sure it's titled Supreme Court Bracket because the bracket consists of cases in which the Supreme Court of the United States made the rulings. [[Special:Contributions/162.158.90.6|162.158.90.6]] 10:35, 24 August 2018 (UTC)

:: I think it would be interesting if someone who knows a little more about the US legal system could write some short fanfic pieces about each of the cases later in the bracket. Maybe write each participant as if they were actually individuals, and try to come up with a reason for each case that's kind of consistent with their previously shown personalities. In cases like NLRB v Brown (mentioned below), you could just link to the case or give a short dramatised summary. For cases that haven't happened in reality, post a short piece describing the case presented, and let people vote on the outcome (as I believe was previously done for another comic about brackets, on Twitter or something I think?). I'd love to see how it went. -- [[User:Angel|Angel]] ([[User talk:Angel|talk]]) 15:38, 25 August 2018 (UTC)

: As I see it (IANAL), the plaintiff goal in the Supreme Court usually is to change something (overrule a previous court decision, repeal a law), while the respondent typically fights to keep things the same. If the plaintiff loses, no changes are made. If nobody sees any changes in the country, why the case would be a landmark? Only when both outcomes change things for many people, like in the Dred Scott case, the respondent win makes a landmark.

I think this comic is unique because the comic references real life events without throwing in any fake events for comic effect. Usually the comic would have some imaginary events included. I guess just the idea that winners of Supreme Court cases are going to come back to the court and compete against each other is comical enough.

I created an image showing the winners superimposed on the original comic so you can see who is due to "play" each other next.

The joke here is simply that, while court cases are competitions, the winner of a case does not challenge the winner of another case (unlike sports tournaments). It's a juxtaposition joke, made funnier by the fact that "court" is used in sports as well. [[Special:Contributions/172.68.189.163|172.68.189.163]] 00:09, 25 August 2018 (UTC)

I just realized that the part of the explanation about the title text is not entirely correct. It mentions that a bracket is busted when a matchup does not have the predicted result, but I think it needs to point out the fact that it's related to any matchup that includes the team you picked to win the bracket instead of just any matchup in the bracket. In summary, if the team you picked to make it past the bracket loses a matchup, you then have no chance of a correct pick for any team from that bracket in later matchups - hence that bracket is busted.

Just as tables cause readability issues, semantic use of italics can cause issues. Specifically, it is not safe to assume that screen reading software will distinguish italicized content such that a blind person will be aware which side won the case in the comic description. It is safe only to explicity indicate the winner through text. [[User:Thisisnotatest|Thisisnotatest]] ([[User talk:Thisisnotatest|talk]]) 07:01, 26 August 2018 (UTC)

939: Arrow

2018-08-23T18:17:41Z

162.158.63.238: /* Trivia */

{{comic
| number = 939
| date = August 17, 2011
| title = Arrow
| image = arrow.png
| titletext = 'The Return of the Boomerang' would make a great movie title.
}}

==Explanation==
The comic appears to be a reference to [[475: Further Boomerang Difficulties]], which had a man throwing a boomerang that never returned. [[Cueball]] shoots an arrow off with a bow and a boomerang returns to him. This confounds him. As it was also a [[Cueball]] that threw the boomerang in the other comic, this may be the same Cueball that now finally has his boomerang return to him after a long time (464 comics later). This would really freak him out then.

The title text is a pun on how boomerangs always come back, along with how "The Return of X" is often used for movie names.

However, as shown in the prequel as well as in an even earlier comic, Cueball/[[Randall]] has to admit: [[I Am Not Good with Boomerangs]]. So for him it would be a surprise if the boomerang returned!

Boomerangs also became a main theme in the interactive comic [[1350: Lorenz]].

==Transcript==
:[Cueball stands with a bow and arrow drawn tightly, aiming off-screen.]
:[He fires the arrow, it disappears offscreen. The bowstring vibrates for effect.]
:[He stands holding the bow by their side, watching the arrow fly away.]
:[A boomerang flies on-screen, coming from the direction the arrow was fired. Cueball reaches up to catch the boomerang.]
:[Cueball is now holding the boomerang, staring at it with confusion.]

==Trivia==
*Part of this comic and [[475: Further Boomerang Difficulties]] is the picture for the {{tvtropes|BrickJoke|Brick Joke}} page on TV Tropes.

*Cueball catches the boomerang in the last panel, even though boomerangs normally have a sharp front edge.

2033: Repair or Replace

2018-08-15T16:32:39Z

162.158.63.238: /* Explanation */

{{comic
| number = 2033
| date = August 15, 2018
| title = Repair or Replace
| image = repair_or_replace.png
| titletext = Just make sure all your friends and family are out of the car, or that you've made backup friends and family at home.
}}

==Explanation==
{{incomplete|Created by a BOY - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

Cueball, likely representing Randall, is in his car. He says that there is a weird sound, so Hairy, representing a car dealer, asks him to lift his hood. In this case the hood probably represents something else, though that might not be the case. Car companies likely have the "economics" figured out, so they can make quick decisions on whether to "repair or replace".
