The puzzle is almost certainly a reference to the Monty Hall problem, since that's usually framed in terms of 3 doors: behind 2 are goats (bad prizes), behind the third is a new (the desirable prize). While the other puzzles share some attributes, I doubt they're intended. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 21:55, 23 November 2022 (UTC)
:Who says goats are a bad prize? If you want to make goat's milk cheese, they are quite necessary. Whereas a car may be a burden, most states still require the recipient to pay sales tax, which can be thousands of dollars.

:Maybe figuring out how to transport the goats in the new car without the goats ruining it would also be a puzzle.[[Special:Contributions/172.71.102.215|172.71.102.215]]

Another problem with the James Webb photo is that, from its orbit, the Earth appears too close to the Sun to be safe to photograph. So, the recipient of the gift would have to travel into deep space, well past the orbit of the Moon, for the shoot.

Wasn't Bobcat in a Box inspired by xkcd #576 and its title text, which wasn't even the first boxed bobcat in xkcd? Feels weird to say that the boxed bobcat is a reference to an external brand and not xkcd's rich internal history of mailing people bobcats.

== "Katherine and Brandon" ==

Could someone explain those Names in the "Chemistry" entry to me? It would be very atypical for Randall to make a mistake in that place, but both seem to be impossible to spell with the periodic table of elements.
Potassium, Astatine and Helium would give K-At-He- (and some radiation posioning) and Iodine and Neon -Id-Ne. But neither Rubidium (Ru), nor Radium (Ra), nor Ruthentium (Ru), nor Rhodium (Rh) nor Radon (RN) give you a pure "R" and likewise there is no Element Ri or Er, so it is impossible to put the "R" into "Katherine".
Likewise "Brandon" could be started with Boron (B), Radon (Ra), Nitrogen (N) and finished with Oxygen (O) and again Nitrogen (N), but there are only two "D"s in the whole peridoic table and both are fixed to other letters, that would not fit: Paladium (Pd) and Gadolinium (Gd).

== Psychology ==

Hi, this is my first edit, I hope I'm doing it right. The psychology example is most likely about the norm of reciprocity (see Wikipedia). It's a very strong norm. Violations of this norm can indeed cause distress to a point where people express anger if they can't reciprocate (which seems somewhat irrational at times).

Talk:2691: Encryption

Robm: Connecting new info to named character Rob

More generally, when the explanation of the encryption algorithm needs example people, it picks names going sequentially through the alphabet. Alice and Bob are the canonical first two, names starting with C and D would be next. Eve, the eavesdropper, is next. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 04:01, 29 October 2022 (UTC)
:...though it depends upon {{w|Alice and Bob#Cast of characters|what other protagonists/required roles}} are to be featured in the scenario as to which initials get given to the 'normal' example correspondants. And I'm sure you could come up with other punny names for other novel roles, if you're in the position to require something special, only Alice and Bob being (normally!) inviolable as to both role and initialism.

Reminds me of a notorious movie from 1969, Bob & Carol & Ted & Alice, a plot point of which is knowledge shared incompletely between the four. I believe the names are coincidental but, not knowing when Alice, Bob, Charles and Diana were first used, it may not be. [[User:Dhugot|Dhugot]] ([[User talk:Dhugot|talk]]) 18:16, 29 October 2022 (UTC)

Since we know without question the name of the female character in this comic, does she join the list of other named characters for every other time we see someone with a similar hairstyle? [[User:Trimeta|Trimeta]] ([[User talk:Trimeta|talk]]) 02:58, 30 October 2022 (UTC)
:Not just yet. Unless we can definitively backdate her hairstyled appearance, but consider it upon reappearance. Three options to do it, though:
:* If there's not enough to split her from Megan (though I think there is), do as we <s>do</s> ''did''  with Rob for Cueball (incidentally mentioned here, but I think there's no category to cover that, just a mention within Megan that there's a not-Megan-but-nearly)...
:* Go for a full new character in her own right if she gets (or has previously gotten, without our realising until now) another distinct appearance or two...
:* If Randall repeats Alice/others in a further series of Alice And Bob 'tales' (plenty of scope for the actual appearance of Eve, or Mallory/Mike or whoever – ''if'' the whim takes him) group her and the 'gang under an "Alice and Bob" entry (e.g. if a clear Ivan appears even just the once, he gets tidily filed under his own subheader there)...
:..definitely some consideration to be had. Anyone could review hairstyles carefully (or dialogue?), both forward and back in time, and propose (or enact?) the solution that you think best applies. It's not up to me with no ability to create (or banish) new pages, but that's my immediate thoughts. [[Special:Contributions/172.70.162.5|172.70.162.5]] 09:34, 30 October 2022 (UTC)

Does this lend new information about named character Rob? The girl has a friend Robert, and this cueball has a brother, which seem to be separate people, both of whom could be called Bob. I don't see a particular connection, but I see there is investigation to who the girl is, and that may lead to something. FWIW I think she looks like Science Girl; based on age alone that could connect her to Bobby Tables. How does time pass in xkcd, do we expect child characters to grow up or remain the same age across comics? We should look across previous Rob comics and see if they're consistent with him being brother to this Cueball. [[User:Robm|Robm]] ([[User talk:Robm|talk]]) 16:36, 30 October 2022 (UTC)robm
