I would like to discuss the policy around asking questions which are intended as setups for a joke. I searched through the meta, and didn't see anything about this directly, so I would like to gauge the community opinion on this.
For an example of what I am talking about, see today's question Two cats on a roof. This question was asked and answered at the same time by the OP, and it is clear that the question is indeed a physics related joke.
Although it is related to physics, I don't think such questions and answers are really useful to the purpose of this site, which is to share knowledge of physics concepts; not to share physics humour. The only reason I second guess it at all is because both the question and the answer seem to have a net positive reception. I assume this is just because people found it "fun"; but having more community opinions on this would help clear up how we should approach such questions and answers.
Please, if you have an opinion one way or another on this, I would be interested in hearing your opinions and seeing what the community consensus is.
I had expected this to be a duplicate, but the closest I could find was Policy regarding intentionally counter-productive users, which isn't really the same situation.
