Old Man Vs Young Punk   

An old man was sitting on a bench in the mall when a young man with spiked hair came and sat down beside him.

The boy's hair was yellow and green with orange and purple streaks. He had black makeup around his eyes. The old man just stared intensely at him for several minutes.

The boy, becoming agitated with the old man's gaze, said "What's the matter, old man. Haven't you ever done anything wild in your life?"

The old man answered. "Well, yes, actually I have. Once I got very drunk and had sex with a parrot. I'm just sitting here wondering if you are my son."
