ok, so Amos Fly. way back, at whatever age it is that we are obsessed with knock-knock jokes, my little bro (ok, he's not so little any more -- has a PhD and a total fam. with kids and stuff. i'd call him "younger", but that makes me feel old ;-P) crossed paths with the following: - Knock, knock - Who's there? - Amos - Amos who? - A mosquito bit me. heh. ;-) ok. so anyone who has ever lived through a kid's joke phase knows that a common side effect is making up their own jokes. which is what happened here. witness: - Knock, knock - Who's there? - Amos - Amos who? - Amos Fly bite me! Which really, though it makes less sense than the original, is funnier.
