A man loses his dominant arm in an automobile accident.
After a few months trying to get used to life without his arm, he falls into a deep depression and decides to end it all. He takes the elevator to the top floor of the tallest building in town and walks to ledge of the roof. As he gazes down at the streets below, he sees a man with no arms, jumping up and down repeatedly, shimmyin' and shakin', hootin' and a hollerin'.
He says to himself, "I was just about to end it all because I lost one arm and there's this guy with no arms jumping for joy. I must know why!"
The man descends the elevator to the ground floor and runs out to the man in the street. He asks, "I was just at the top of that building ready to jump off because I lost my one arm, and then I saw you jumping for joy. You don't have any arms. What's the secret to a happy life?"
And the man says, "The f%^& are you talking about? My balls itch and I can't scratch them!"
