The Old man and the Parrot

An old man was sitting on a bench in the mall when a young man with spiked hair came over and sat down beside him. The boy's hair was yellow and green and orange and purple. He had black makeup around his eyes. The old man just stared at him. The boy 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. I once got drunk and had sex with a parrot. I was just wondering if you were my son.
