A punk rocker type boards a bus. He's wearing a leather vest and pants, studded collar and cuffs, and he's sporting an 8" mohawk hairdo in a rainbow of colors.
An old guy just stares at him. Finally the punk looks over at the old guy and says: "What'sa matter old man. Didn't you ever do anything wild in your life?"
The old guy looks back and says: "Yeah... I fucked a parrot one time. Thought you might be my kid."
