A young punk gets on the cross-town bus. He's got spiked, multicoloured
hair that's green, purple and orange.  His clothes are a tattered mix of
leather rags.  His legs are bare and he's wearing worn-out shoes.
 His entire face and body are riddled with pierced jewellery and his earring
are big, bright feathers. He sits down in the only vacant seat, directly
across from an old man who glares at him for the next ten miles.
 Finally, the punk gets self-conscious and barks at the old man: "What are
you looking at you old fart...didn't you ever do anything wild when you were
young?"
 Without missing a beat, the old man replies: "Yeah, back when I was young
and in the Navy I got really drunk one night in Singapore and had sex with
a parrot.... I thought maybe you were my son."
