A rooster lays an egg at the very top of a slanted roof Which side is the egg going to roll off on?

Um, roosters don't lay eggs, the hens do! (Nice one!!)

I disagree .. The question clearly states that a rooster had laid an egg ... The fact that a Rooster has laid an egg is irrelevant.

Clearly the egg will go nowhere because it is balanced perfectly on the tip of the point!

Errrrr..... If you look in joke books, it says: It didn't roll because roosters don't lay eggs! I know that because my nephew loves joke books and he sent me one for Christmas last year. Yeah, great joke!
