SNYDER: One day the campus is completely bare. Empty. The next, there are children everywhere. Like locusts. Crawling around, mindlessly bent on feeding and mating. Destroying everything in sight in their relentless, pointless desire to exist.
GILES: I do enjoy these pep talks. Have you ever considered, given your abhorrence of children, school's principal was not, perhaps, your true vocation?
SNYDER: Somebody's got to keep an eye on them.
