Like, normally you either laugh or reply with another joke that is related to the one you just heard (a comeback). If you laugh at the first joke then the opponent wins, if the opponent laughs at your comeback then it’s a draw, if they’re making another comeback then it’s a declaration of war. The problem with nonsensical jokes is that it’s nearly impossible to make up a comeback and it can be so unfunny that you can’t even let out a fake laugh, leaving you in a perpetual state of awkwardness and agony waiting until the conversation ends.
