A young man with a wild and multi-coloured hairstyle sits next to an old man on a park bench. The old man stares at the young man.
"What's the matter, old man?" says the young man. "Never done anything crazy in your life?"
The old man replies: "Yeah. When I was in the Navy, I got really drunk one night and had sex with a parrot. I tought you might be my son."
