A teenager takes a seat on a bench next to a middle aged man reading a newspaper. After a few minutes the man looks over and stares intensively on the youth’s multicolored mohawk.
The teenager looks over at the man and says: “What’s the matter old man, never done anything interesting in your life?”
The man responded: “I once got drunk and had a wild night with a parrot. Now I was just wondering if you were my son.”
