A big, muscular guy with a tiny head walks into a bar and up to the bartender. The muscle guy looks depressed. The bartender, dying to ask the question, proceeds:
"Dude, I don't mean to be a jerk but you've got a giant muscular body and yet you have this tiny head. What happened to you"?
Muscle guy: "Well, I was in Africa last year and I saved this really hot witches life.
In return she said she would grant me any wish I wanted.
Being as hot as she was I naturally told her that I wanted to make love to her.
She said that can't happen because she would lose all of her powers. So I asked her- okay, how about a little head.
Poof!
