Once upon a time, a guy was sitting at a bar. He was throwing money around, giving the barman £50 tips and buying drinks for everyone. He was surrounded by a crowd of adoring women.
The barman liked the tips, but he was kind of curious about a little man that would jump from the rich guy's pocket. The little man would run up and down the bar, kicking over the bowls of peanuts and giving people the finger. Then the little guy would jump back into the man's jacket for a while.
The barman went over and asked the guy what was up.
So the rich guy says, "Well, let me tell you a little story. I was walking along a beach one day, and I come across this lamp. I rub it, and a genie pops out. I got three wishes, so my first wish was to be fabulously wealthy. Then I wished for a harem. You can see I got both."
The barman asks, "So what about your third wish?"
"Oh, that," mumbles the rich guy, pointing to the little man. "That's the twelve-inch pr**k I wished for."
