Minerva: Well, clearly the question is an example of what one might call anti-humor. The majority of jokes involve a clever punchline of some kind, a play on words, so the obvious answer of To get to the other side, which might otherwise have no other comedic value in and of itself, generates a laugh by simply defying the norm of joke telling. However, this particular joke has been so overused as to become trite and cliché. To be perfectly honest, I didn't find it particularly funny the first time I heard it; it's very simplistic, cheap humor, that requires absolutely no knowledge of psychology or quantum physics.
Artemis: Thank you, I couldn't have explained it better myself.
Holly: ...Somebody shoot me. Hey, Butler? I think now would be a good time to have that talk about jokes.
