A young punk with spiked red, green and yellow hair sits down on a bus bench next to an older man. The older man looks over and stares at the teenager's hair.

"What's the matter, old man?" sneers the punk. "Haven't you ever done something just for the fun of it?"

"Sure," says the senior. "When I was in the army, I was stationed in Singapore. One night I had way too much to drink, and had sex with a parrot. Are you my son?"
