@Jester: If somebody shoved me off a building as zombie bait, then they'd better hope I don't escape their attack as an infinitesimal mite (which I will try my best to do), because if I do, then I'm gonna try my best to come back as Mega-Wulf and stomp 'em. Then stomp 'em some more, and then toss their body, barely clinging to life, into the oncoming zombie swarm.
@Philote: Imagine trying to divide your essence (we'll call you 1) into a completely empty area, like, say, outer space (which we call 0, because it's empty); each of your particles go shooting off into the far reaches of space, never to reach an end. That's what you're theoretically doing to a number when you divide it by zero. The number is essentially vaporized, in a futile attempt to fill the void of the infinite nothingness that is 0. Kinda scary when you think of it.
