An old man was sitting on a bench at the mall.  A young man walked up to
the bench and sat down.  He had spiked hair, all different colors -
green, red, orange, blue and yellow.  The old man just stared. The young
man said, "What's the matter old timer?  Never done anything wild in
your life?"

The old man replied, "Got drunk once and had sex with a parrot.  I was
just wondering if you were my son."
