Cool Zen II - Old & Punk

There was an old man in a bar who was staring at a punk in the corner. The punk had multicolored, spiked hair and multicolored feather earings.

After a while the punk got mad and said to the old man “What are you staring at?”

“Back when I was in the army I got really drunk one night and had sex with a parrot.
I was wondering if you were my son.”
