Well, these questions are stupid, funny and revealing at the same time - and more important, they tickle a certain nerd sense. One that will make people eager to shine and steal the show. I can't throw a stone, as this includes me as well.
Like @Chenmunka, I would give them some credit as beeing on topic, but not helpful in a technical way. They satisfy a shallow curiosity of the BuzzFeed kind.
I try to either use them as a hook to provide some basic understanding or debunk them as the nonsense they are (nicly both citd questions also show the atempts I tried :))
Like with many other borderline questions it's hard to kick them out easy. I think we should give alike questions a (short) time to see if someone can come up with a good way to transform it into knowledge. This ofc, does not include questions about ponies.
