Apart from my "jokey" retort TCL, I agree it is rather an odd topic, if their aim is to stop the chatty threads which lighten up the day, then cancel the jokes one and allow the banter (but not the stupid Q's - like did you eat your cereals this morning, if so what were they?).
it's under Phrases & Sayings. And in looking for it I discovered that there's a Riddles subsection in Quizzes & Puzzles, rendering my previous post inoperative. Sorry.
