A young punker gets on the cross-town bus. He's got spiked, multi-colored hair that's green, purple and orange. His clothes are a tattered mix of rags, his legs are bare and he's without shoes.
His face and ears 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 about ten miles.
Finally the punk gets self conscious and spits at the old man: "What 'er you starin' 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 in the Navy I got real drunk in Singapore and screwed a parrot. I thought maybe you were my son."
