''{{w|Wirecutter (website)|Wirecutter}}'' is a product review website owned by ''The New York Times''. Randall is parodying the website by having them &amp;quot;review&amp;quot; the 70 most popular [[:Category:Religion|religion]]s. Product review websites typically make posts with the &amp;quot;best&amp;quot; X, e.g. &amp;quot;Best smartphones&amp;quot;, or &amp;quot;Best laptops&amp;quot;. These reviews are useful for consumers trying to choose among the wide variety of products available. &lt;br /&gt;
&lt;br /&gt;
There is also a wide variety of religions. However, unlike electronic devices, a person does not usually choose their religion; they are taught one during childhood and most remain in that religion their entire life. Changing religions is a significant life event. More specifically, many variants of the three major {{w|Abrahamic religions}} promote {{w|Religious exclusivism|exclusivity}}, and do not recognize other religions as valid. They emphasize the importance of belief in specific creeds. Members of those religions might not recognize a reviewer as having truly &amp;quot;tried&amp;quot; their religion if their intent was always to move on to another.&lt;br /&gt;
&lt;br /&gt;
A post &amp;quot;reviewing&amp;quot; religions is sure to stir up controversy, as most religious followers are passionate about their religious beliefs and don't want to be compared against other religions. {{w|Religious_war|Literal wars}} have been fought over the idea one religion could be superior to another, and it is not a wound most practitioners are willing to reopen any time soon. Moreover, religions are typically chosen for more fundamental reasons -- such as by comparing the likelihood that each religion makes accurate claims, or the efficacy of each religion in promoting an ethical life, or the connection a practitioner feels to the religion's rituals, metaphors, and images, or by privileging a preexisting cultural or family connection to a particular tradition -- not by comparing gimmicky features or price. &lt;br /&gt;
&lt;br /&gt;
The title text mentions &amp;quot;budget&amp;quot; and &amp;quot;upgrade&amp;quot; picks, which are subcategories for reviewers - cheaper options and options that are good for upgrading your current product to a newer one. Neither of these categories are typical categories for religions and would further anger their adherents. The idea of paying for religion brings to mind {{w|tithe|tithing}}, {{w|televangelism}}, {{w|indulgences}} and {{w|Prosperity theology}} - highly controversial practices.&lt;br /&gt;

The Nobel Prize is a set of prizes awarded in memory of Sir Alfred Nobel to, &amp;quot;those who, during the preceding year, have conferred the greatest benefit to humankind.&amp;quot;&lt;br /&gt;
In this comment a nobel prize is being awarded for the discovery of two new Nobel prizes. This parallels Nobel Prizes awarded for the discovery of new elements. However, unlike elements, Nobel Prizes cannot be discovered.&lt;br /&gt;
The comic suggests that the doctor being awarded the prize came up with the idea of &amp;quot;discovering&amp;quot; Nobel Prizes, and no one can figure out how to stop awarding them to her.  &lt;br /&gt;

&lt;div&gt;It IS possible to go smaller than one atom, but it tends to make a really bright flash and loud noise. The original atomic bomb was the second guy's reading of a train modeler's notes, miraculously preserved in a refrigerator. --[[Special:Contributions/68.200.188.141|68.200.188.141]] 03:37, 29 January 2013 (UTC)&lt;br /&gt;

3.5mm per foot?  What kind of half-assed system is that??  It's an embarrassment.  [[Special:Contributions/108.162.219.58|108.162.219.58]] 21:13, 5 February 2014 (UTC)&lt;br /&gt;
&lt;br /&gt;
3.5 millimeters is due to the origins of HO scale.  It literally means &amp;quot;Half O&amp;quot;, and &amp;quot;O&amp;quot; scale, now 1/4 inch per foot in the US, was 7 mm/foot in Britain, where the scales originated.  The debate over &amp;quot;HO&amp;quot; and &amp;quot;H0&amp;quot; comes from the same source, as &amp;quot;O&amp;quot; scale was originally labeled &amp;quot;0&amp;quot;, following the larger scales of 1, 2, 3, etc, used for toy trains in the early 20th century.  As for the name today, it's pronounced &amp;quot;Aitch-Oh&amp;quot; in most, if not all, of the world. {{unsigned ip|173.245.50.92}}&lt;br /&gt;
&lt;br /&gt;
:In Germany this scale is called &amp;quot;H-Null&amp;quot; (H for halb=half; Null=zero). So H0 is definitly correct there while HO is completly illogical. The HO can be used in english only because it is common to use O instead of saying zero, while this is uncommon in most other languages.

Additionally because there was a = in one parameter it treated everything before as the parameter name and everything after it as the parameter value. If the first problem wouldn't be a problem at least the first parameter would need to be defined as 1=…. I reverted that part to the old working version.

There is a [[explain_xkcd:Community_portal/Proposals#Merge_Cueball_.26_Rob|community portal discussion]] of what to call Cueball and what to do in case with more than one Cueball. I have added this comic to the Category:Multiple Cueballs. Since the one who knows the rule to me seems like the best candidate for a Cueball here, I have changed the transcript to make him Cueball. He has the interesting comments of this comic, so maybe it is OK to let him be listed as Cueball? On the other hand someone has previously done the opposite, proving that it is not possible to say that Cueball is any particular guy. But it is just easier to explain the transcript (and the comic) when calling one of them Cueball rather than guy 1 and 2 (left of right etc.)--[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 14:11, 29 July 2015 (UTC)--&lt;br /&gt;

The original width of the section of real world being modeled (18m * 87) works out to 1 mile. [[User:Johanna-Hypatia|Johanna-Hypatia]] ([[User talk:Johanna-Hypatia|talk]]) 21:15, 26 September 2016 (UTC)&lt;br /&gt;
&lt;br /&gt;
Is this really a sensible interpretation of the &amp;quot;philistines&amp;quot; comment? It seems to hinge on more obscure, original use of the word, and slightly far-fetched. In particular, considering Munroe's other [[922|comments]] on that movie, I had assumed they were considered philistines simply for cluttering the rulebook with needless pop-culture references, as per the more common definition given on the {{w|Philistinism|wikipedia page}} of &amp;quot;[A person with a] lack of and an indifference to cultural and æsthetic values&amp;quot;.[[User:Thomson&amp;amp;#39;s Gazelle|Thomson&amp;amp;#39;s Gazelle]] ([[User talk:Thomson&amp;amp;#39;s Gazelle|talk]]) 11:50, 6 March 2017 (UTC)&lt;br /&gt;
&lt;br /&gt;
Fight Club has also been referred to (at least) in [[922: Fight Club]]. I think this should be mentioned, but I'm not sure how to work that into the current text. [[Special:Contributions/162.158.238.113|162.158.238.113]] 20:53, 9 December 2017 (UTC)&lt;br /&gt;

There are 2FA USB keys (WebAuthn, FIDO2, U2F) such as&lt;br /&gt;
https://shop.nitrokey.com/shop/product/nk-fi2-nitrokey-fido2-55 with a hole to attach a keychain - and the item in the last panel looks a bit like such one [[User:Bmwiedemann|Bmwiedemann]] ([[User talk:Bmwiedemann|talk]]) 03:48, 30 September 2021 (UTC)&lt;br /&gt;
:: First thing that comes to mind when someone mentions a 2FA security key. 100% most certainly what they are talking about. yubikey/fido2 being the ones that popularized it iirc [[Special:Contributions/172.69.71.177|172.69.71.177]] 04:41, 30 September 2021 (UTC)&lt;br /&gt;
:: Yeah, yubikey definitely comes to mind. I wouldn't call 2FA on a phone a 2FA &amp;quot;Key&amp;quot;. Perhaps you could call the generator secret a (cryptographic) key, but I don't think that's what this comic is talking about. [[User:Jeffkmeng|Jeffkmeng]] ([[User talk:Jeffkmeng|talk]]) 06:56, 30 September 2021 (UTC)&lt;br /&gt;
2FA tokens are actually quite often physical keys that fit on a keychain and produce a secret number to input for authentication. It is only recently that such 2FA key generators have moved into phones. Here is one example: https://en.wikipedia.org/wiki/RSA_SecurID&lt;br /&gt;
[[User:Adron1111|Adron1111]] ([[User talk:Adron1111|talk]]) 06:41, 30 September 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
The joke here isn't 2FA key vs tumbler-and-pin key, the joke is that all of the configuration pain he's talking about isn't setting up the key to work with his computer or various sites (which one might expect when introducing a new, non-tech-savvy user to 2FA), but rather getting the key onto his keyring.  [[Special:Contributions/172.69.34.67|172.69.34.67]] 07:22, 30 September 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
Haven't put this in the text (I added some practical &amp;quot;what you know/have/are&amp;quot; stuff, from my own past experience) but I first thought it was that two ''actual'' factors are now on the keyring (insecurely, as per the current last para?). A 'have' item is obviously there, of whatever form, but now (unless it's a second 'have', supposed to be separate) there is also somehow a 'know' one (c.f. those people who have scrawled their bank-card PINs onto their bank-cards, entirely negating that particular safety-factor) or an 'are' one (bits of fingerprint? blood samples?). Possibly now imposssible to use (if not trivially easy to co-steal). Plus, remember that data security has two faces: 1) Only those authorised may access/change data; 2) Those who are authorised should not be deprived of this ability. It is commonly the second that require a second factor (separate email/phone contact) to get around problems with the first (forgotten password), though it isn't really an everyday 2FA application, just a backup 1FA method (as with &amp;quot;Name of first pet&amp;quot;, etc).

Having noticed that 85 KPH is slower than 85 MPH, it took me a while to work out that 85 MPH is much slower than 68 km/s (and I was blindly assuming that the universe is at least one megaparsec in radius), after which the title-text joke started making sense.  Congratulations on being almost too subtle for me.00:46, 16 September 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
Is the 85 mph number significant in any way?  Why does &amp;quot;Dave&amp;quot; who points radar guns in random directions get this number? [[Special:Contributions/108.162.245.167|108.162.245.167]] 03:41, 16 September 2021 (UTC)&lt;br /&gt;
Well, it's probably over the speed limit in most places. Maybe Dave is a traffic cop? --[[Special:Contributions/172.68.129.137|172.68.129.137]] 04:55, 16 September 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
Unfortunately, the explanation only explains the things everyone can read on the internet anyway. 85 mph or 85 km/h have the wrong unit, because for the expansion speed we need to look at two points of space, measure how fast they move away from each other. Obviously this should be a number that increases linearly with the distance of the two points (if space is created equally everywhere in the universe). Thus the 85 km/h misses the length. Is the joke here that a random dudes results are reported equally (false equivalence)? --[[Special:Contributions/162.158.93.142|162.158.93.142]] 04:41, 16 September 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
Dave again: &amp;quot;But when they hit 88 mph, we're gonna see some REALLY weird shit!&amp;quot; [[User:RAGBRAIvet|RAGBRAIvet]] ([[User talk:RAGBRAIvet|talk]]) 06:50, 16 September 2021 (UTC)&lt;br /&gt;

&lt;br /&gt;
Relating (coincidentally) with several of the above comments, I added in a &amp;quot;what Dave could be measuring&amp;quot; paragraph (ultimately: just traffic!), via a diversion where I totally messed up a factor and it sent me down a rabbithole of completely the wrong distance! ((Sanity-check my new figures, please: e.g. 85mph =&amp;gt; ~0.038km/s =&amp;gt; ~0.0005588(of the 68km/s/Mpc figure) =&amp;gt; therefore 558.8pc, etc and onwards)) Anyway, perhaps Dave just is/wants to be a traffic-cop? (If you can find humour in the 'all directions' - presumably ''away from'' - then obviously supercede the 'both directions' bit.)

Are (6) and (7) about completing sequences?&lt;br /&gt;
&lt;br /&gt;
If the sequence was [1, 2, 3, ?] we would expect the ? to be a placeholder for 4. So [1, 2, 3]+2 is wrong := FALSE. But [1, 2, 3]+4 is correct := TRUE. {{unsigned ip|141.101.99.22}}&lt;br /&gt;
&lt;br /&gt;
&amp;quot;+2 appears to be applying a unary + to the number 2&amp;quot; : or it adds the number of the line, 10, to 2 =&amp;gt; 12. Also, the eleventh line, &amp;quot;2+2&amp;quot; may add 2 to all the following 2, explaining line 12. (that theory is from a friend of mine) [[User:Seipas|Seipas]] ([[User talk:Seipas|talk]]) 12:17, 12 June 2015 (UTC)&lt;br /&gt;
: Also, for the lines 6 and 7, the operation &amp;quot;[1,2,3]+x&amp;quot; may add x to the set [1,2,3] and return true if the operation succeeded or false if not. Adding 2 to the set [1,2,3] returns false because 2 is already in [1,2,3]. [[User:Seipas|Seipas]] ([[User talk:Seipas|talk]]) 12:23, 12 June 2015 (UTC)&lt;br /&gt;
:: I thought it was doing element-wise addition and then comparing &amp;quot;[6] &amp;gt; [3,4,5]&amp;quot; (using the line number in the joke, like in line 10). The problem here is that line 6 should return true and line 7 should return false. [[User:Rand|Rand]] ([[User talk:Rand|talk]]) 15:46, 13 June 2015 (UTC)&lt;br /&gt;

Yellowish Blue: http://www.livescience.com/17948-red-green-blue-yellow-stunning-colors.html is NaN! {{unsigned ip|108.162.221.129}}&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
''&amp;quot;The ironic thing is that fractions with 2 in the nominator are not the kind of numbers that typically suffer from floating point impreciseness.&amp;quot;''&lt;br /&gt;
- This is not technically correct.  Should read &amp;quot;fractions with 'power of 2' in the '''de'''nominator.  However, the 3/2 would cause precision errors. {{unsigned ip|108.162.221.129}}&lt;br /&gt;
: I don't know proper English wording for things, but 3/2=3*2^-1, so it would be represented exactly under IEEE-754 too. [[Special:Contributions/141.101.89.217|141.101.89.217]] 13:58, 12 June 2015 (UTC)&lt;br /&gt;

Is there more to this comic, a fixed set of rules that can tie all the examples together, or does each line make its own joke independently? [[Special:Contributions/108.162.219.5|108.162.219.5]] 12:54, 12 June 2015 (UTC)&lt;br /&gt;

&lt;br /&gt;
&amp;lt;blockquote&amp;gt;This would make sense if it was &amp;lt;code&amp;gt;[] + 2&amp;lt;/code&amp;gt;&amp;lt;/blockquote&amp;gt;&lt;br /&gt;
&lt;br /&gt;
It really wouldn't. Javascript returns &amp;lt;code&amp;gt;&amp;quot;2&amp;quot;&amp;lt;/code&amp;gt; (god knows why) and Python gives an error. Don't really feel like testing many other languages, but I also think it's not really a logical assumption to make at all. Can't think of a reason for &amp;lt;code&amp;gt;[] + 2&amp;lt;/code&amp;gt; to return &amp;lt;code&amp;gt;[2]&amp;lt;/code&amp;gt;... ever. It ''might'' make a little bit of sense in Randall's oddly typed language, but not in any sane one. --[[User:TotempaaltJ|TotempaaltJ]] ([[User talk:TotempaaltJ|talk]]) 12:35, 12 June 2015 (UTC)&lt;br /&gt;
&lt;br /&gt;
: Javascript first converts &amp;lt;code&amp;gt;[]&amp;lt;/code&amp;gt; (the empty array) to the empty string (using the rule &amp;quot;stringify each element and join with a comma&amp;quot;), then treats the operation as &amp;lt;code&amp;gt;&amp;quot;&amp;quot; + 2&amp;lt;/code&amp;gt;, which results in conversion of the other operand to string and then concatenation.

I think a lot of this is his joke about programming languages loving the number 4. 2 + &amp;quot;2&amp;quot; = &amp;quot;4&amp;quot;, [1,2,3] + 4 = true, 2+2 = DONE, and the range one all seem to support this. Also reminds me of this: http://xkcd.com/221/ {{unsigned ip|173.245.52.112}}&lt;br /&gt;

:::Since this is a Programming language, it must be talking about RGB colors, where green is a base color and yellow is mixed using red and green. So a &amp;quot;yellowish blue&amp;quot; would contain all base colors, resulting in white – and that's propably why Randall's language returns NaN.[[Special:Contributions/141.101.92.42|141.101.92.42]] 08:39, 13 June 2015 (UTC)&lt;br /&gt;

&lt;br /&gt;
:::You're talking about the {{w|RYB color model}}, whereas most programming languages work in the {{w|RGB color model}}, where yellowish blue is undefined. [[Special:Contributions/188.114.97.151|188.114.97.151]] 23:30, 29 December 2015 (UTC)&lt;br /&gt;
&lt;br /&gt;
:It's a lot simpler than that. Perceptually there is no yellowish-blue, one would never describe a blue as being yellowish. If you add yellow to blue you get greenish-blue, add more and you get green, then yellowish-green, then greenish-yellow. At no point would you describe the colour as either yellowish-blue or bluish-yellow. This is why it's the equivalent of NaN, you can use the language to tell the machine you want the result of &amp;quot;2/0&amp;quot;, or you want the result of &amp;quot;blue with a yellowish tinge&amp;quot;, but in either case it is not possible to represent the result. {{unsigned ip|141.101.98.154}}&lt;br /&gt;

Note that some programming languages avoid the problem of overloaded '+' operator between operands of vividly different types by using other symbols for string concatenation (be it &amp;quot;a&amp;quot;~&amp;quot;b&amp;quot; or &amp;quot;a&amp;quot;.&amp;quot;b&amp;quot;) and numerical addition.  The real WTF is abusing '+' for string concatenation, which has very different properties from numerical addition, not being symmetrical for example: concat(&amp;quot;aa&amp;quot;, &amp;quot;bb&amp;quot;) == &amp;quot;aabb&amp;quot;, while concat(&amp;quot;bb&amp;quot;, &amp;quot;aa&amp;quot;) == &amp;quot;bbaa&amp;quot; != &amp;quot;aabb&amp;quot;. --[[User:JakubNarebski|JakubNarebski]] ([[User talk:JakubNarebski|talk]]) 17:38, 12 June 2015 (UTC)&lt;br /&gt;

;+2&lt;br /&gt;
I think this is a japanese language joke. The + sign can also refer to the kanji 十, which is 10 in japanese. This would explain the result being twelve. 十二, or 10 2, is twelve in japanese. {{unsigned|Rafaeladson}}&lt;br /&gt;
&lt;br /&gt;
I think number 5 is an escaped quote (two consecutive double quotes yields one double quote), a plus sign, and another escaped quote. The result is shown with an alternate form of escaped quotes (the apostrophe and double quote can both be used to show a string). NSIS scripting language uses this notation.[[Special:Contributions/108.162.221.180|108.162.221.180]] 20:19, 12 June 2015 (UTC)&lt;br /&gt;

Great job at explaining the outputs. I clearly would have missed some interpretations without your insights. [[Special:Contributions/108.162.254.146|108.162.254.146]] 21:10, 12 June 2015 (UTC)&lt;br /&gt;
&lt;br /&gt;
The joke on line [10] really doesn't seem to be a Chinese/Japanese language joke. We can see that the language interacts much more directly with line numbers from the inter-line joke between lines [11] and [14], where line [12] becomes [14] because the value of 2 has become 4. This is provable by observing that the line after [14] is [13], showing that the previous line really is still line [12], it simply displays as [14] because the value of 2 has changed. This absurdly direct interaction between the code and its line number makes the joke on line [10] make a lot more sense, as a Chinese/Japanese language joke here seems much too contrived and out-of-place considering the nature of the other jokes in the comic. Not to mention, if the joke on line [10] was really concerning the code's interaction with its line number, it would set up nicely for introducing the inter-line joke between lines [11] and [14].[[Special:Contributions/188.114.106.89|188.114.106.89]] 03:35, 13 June 2015 (UTC)&lt;br /&gt;

&lt;br /&gt;
As a speaker of Japanese, the explanation &amp;quot;[In the Japanese number system] the plus sign is instead the symbol 十&amp;quot; sounds even more absurd than if someone said that English speakers use the small letter &amp;quot;t&amp;quot; as an addition symbol. &amp;quot;十&amp;quot; (ten) and &amp;quot;＋&amp;quot; (full-width plus) are different glyphs and using them interchangeably would certainly not be useful. Although depending on language skill and display font they may visually seem more equal than they're supposed to. 08:28, 13 June 2015 (UTC)&lt;br /&gt;

* #5—I'm surprised we've missed the obvious joke: quotations within quotations.  the double-quatation &amp;quot;I think so.&amp;quot; gets single-quoted within another quotation: &amp;quot;He said, 'I think so.'&amp;quot;&lt;br /&gt;
* The word is &amp;quot;complements&amp;quot;, not &amp;quot;opposites&amp;quot;, on the colour wheel.  I think the joke is likely that most people think of &amp;quot;yellowish blue&amp;quot; as &amp;quot;green&amp;quot;—as it would be on an artists' colour wheel.  Regardless, complements on an RGB colour wheel should not result in NaN—it would result in a mix of yellow (255, 255, 0) and blue (0, 0, 255), which is white (255, 255, 255).&lt;br /&gt;

In response to the comment above that  a mix of yellow (255, 255, 0) and blue (0, 0, 255) would be white (255, 255, 255): you could just as easily claim that the result would be black (0, 0, 0) ;-)  [[Special:Contributions/162.158.3.12|162.158.3.12]] 00:59, 15 June 2015 (UTC)Martin&lt;br /&gt;

{{incomplete|Created by an INFINITE SCROLLING HEAVEN. Please please please please PLEASE do NOT delete this tag too soon!!}}&lt;br /&gt;
A user with a profile picture of {{w|John of Patmos}} posts the Bible text from [https://www.biblegateway.com/passage/?search=Revelation%206%3A12&amp;amp;version=KJV Revelation 6:12] on a social media website. A news channel social-media monitor understands this to be an actual natural disaster in progress and asks for permission to use the posted information in a broadcast. It is not clear if &amp;quot;John&amp;quot; is creating a fictional live-tweeting of the events of the Bible (perhaps as commentary on the apocalyptic nature of the COVID-19 pandemic) or actually truly relaying current events.&lt;br /&gt;
&lt;br /&gt;
The joke is that often &amp;quot;breaking news&amp;quot; organizations may care very little about the veracity of story in itself, its victims or its survivors. They could be thinking only about the views and ad revenue that they think the coverage of the story will generate. As well as trying to ask for republishing permission, to cover modern legalities, there is also a typically bland statement of concern such that the Channel 9 News correspondent does not look entirely uncaring for John's family's safety. The reply may seem underwhelming, given the Revelations-type nature of the scenario, but this early in the news cycle the reporter may not have enough facts from which to respond proprtionally.&lt;br /&gt;
&lt;br /&gt;
The title text modifies verse 14 from &amp;quot;And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places.&amp;quot; to instead reference the {{w|scrolling#Film_and_television|infinite scrolling}} of a {{w|News ticker}}.&lt;br /&gt;
