The Punk

An old man was sitting on a bench at the mall. A young man walked up and sat down next to him. He had spiked hair in different colours; green, red, orange, blue, and yellow and a ring through his nose.
The old man just stared at him.
The young man turned to him and said sarcastically, 'What's the matter old-timer, never done anything wild in your life?'
Without batting an eye, the old man replied, 'Got drunk once and f*cked a parrot. I was just wondering if you were my son.'
