Here's a good one....
An old man was sitting on a bench at the shopping mall. A young
man walked to the bench and sat down. He had spiked hair in all
green, red,orange, blue, and yellow. The old man just stared.
Every time he young man looked, the old man was staring. The young man
finally said sarcastically"What's the matter old man? Never done anything
wild in your life?
Without batting an eye, the old man replied, "Got drunk
once and had sex with a peacock I was just wondering of you were my son"
