A young punker gets on the cross-town bus. He's got spiked, multicolored hair that's green, purple, and orange. His clothes are a tattered mix of leather rags. His legs are bare and he's without shoes. His entire face and body are riddled with pierced jewelry and his earrings are big, bright feathers. He sits down in the only vacant seat, directly across from an old man who just glares at him for the next ten miles.

Finally, the punk gets self conscious and barks at the old man: "What are you looking at you old fart? Didn't you ever do anything wild when you were young?"

Without missing a beat, the old man replies: "Yeah. Back when I was young and in the Navy, I got really drunk one night and had sex with a parrot. I thought maybe you were my son."
