A young punk gets on the cross town bus and sits down in the only vacant seat, directly across from an old man.
The young punk has spiked, multi-colored, green, purple, and orange hair. His clothing is 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 red, yellow and green feathers.
The old man glares at the young punk for him for the next ten miles, as the bus travels across the city.
Finally, the punk looks across at the old man, and yells, "What are you looking at, old man! Didn't you do anything wild when you were young?"
Without missing a beat, the old man replies, "Yeah. Back when I was very young and in the Navy, I got really drunk in Singapore and had sex with a parrot... I thought you might be my son."
