cat mum: what's 6 times 7?
cat boy (making faces): 6 7!!!
cat mum: hilarious, as always. but actually ...?
cat boy: 42
cat mum: 6 x 7 - 6 7 - is 42?!
cat boy: yeah ... so?
cat mum (making faces): that means 6 7 is the answer to the ultimate question of life, the universe and everything!
cat boy: daddy! mommy's being weird again!
cat dad: aww, you see son, - your mommy is just a huge dork!
cat mum: history doesn't repeat itself, but it rhymes!
Isn't that actually canon though? Cause the first book says the answer to the life, universe, and everything is 42, but then what is the question? And I think in the second book they answer that the question is 6x7
Edit: I was wrong, its actually 6x9. Which means Litterbox Comics only read the first book and is a poser and a fake fan. Probably only watched the movie sigh /s
In my defense of failing to remember the correct question, it has been awhile since I read the books.
The reason, or at least a significant part of the reason, if not the complete reason, that Arthur derives that question in particular is because he's a result of the corruption of the calculation caused by the arrival of the B Ark of Golgafrinchams on Earth.
If Arthur had actually been a six foot tall Earth-ape descendant as described by the guide, his brain would have contained the actual answer rather than something almost but not quite totally unlike the true question.
But then the universe would have popped out of existence and been replaced by a more complicated one.
Again.
So we got lucky there.
