This guy with a really small head walks into a bar. The bartender asks him, "Why is your head so small?"
He replies, "I was stuck on this island and there was nothing but beautiful women there who had never seen a man before. So I had sex with all of them. Their leader, who was the most beautiful of all, had the power to grant anybody who pleased her people one wish, and she said I could have that wish. So I asked her to have sex with me. she said she would grant me anything but that, so I said, "Would a little head be out of the question?"
