Two men were seated, rather uncomfortably, next to each other on
a commuter bus.  One was a very straight-laced lawyer-type in his 
forties dressed in suit and tie, the other a young punker with 
purple and pink hair, and clothing adopted from the local welfare 
office.

During the ride it became apparent to the punker that the civilian 
could not take his eyes off of him. The stare was so intense that 
the punker became more and more uncomfortable. Finally, when he 
could stand it no longer, the kid turned to the older and said, 
"Hey, man, what is your problem?  Didn't you
ever do anything sort of outrageous when you were 22 years old?"

"As a matter of fact, I did," said the businessman. 
"When I was 22 I had sex with a parrot and I was wondering if you 
might be my son."
