The most shocking Halloween-related thing ever -- with the possible exception of the joke about Mrs. Ghost not being able to get pregnant because Mr. Ghost had a hollow weenie. But in a respectable 2nd place, anyway, is Halloween, the horrifying tale of an evil madman named Mike Myers (as if his Simon character wasn't chilling enough) who terrorizes a babysitter by putting on a jumpsuit and hiding in the hedge. (A technique now widely used by custodians the world over.)
