An old man is sat down on a park bench when a young lad with multi-coloured, spiky hair sits down next to him. In his hair are bright reds, oranges, blues and yellows. The lad spots the man staring and tries to ignore him, but finally snaps after a good five minutes of solid staring. He shouts to the old man:- "What's up Grandad? Never done anything stupid in your life?" To which the old man replies:- "Course I have, I once shagged a parrot and was wondering if you were my son?"
