I think this is pretty hilarious:
One night a Father was getting his son ready for bed so his son said "Daddy can you tell me a story?" then the father said "O.k. Once Upon a Time there was a bunny...." The son didn't like it so he said "No I want more of a science fiction story." The father just decided to go along with it. "O.k. Once Upon a Time there was a bunny in space" The son still wasn't very satisfied with the story so he said "No I want more of an adult science fiction story" The father the said "O.k. Once Upon a Time there was a naked bunny in space." The son stayed with that story.
