There is a relationship between humor and fear. Think of all the gags you ever heard that have to do with dismemberment, or something that's horrible in one way or another, even if it's just horrible in the sense that somebody's being embarrassed. What do kids laugh at? Kids laugh if your fly's down. That's hilarious. But for the kid whose fly is down, it's a horrible situation.
Stephen KingBut writers INVITE ghosts, maybe; along with actors and artists, they are the only totally accepted mediums of our society. They make worlds that never were, populate them with people who never existed, and then invite us to join them in their fantasies. And we do it, don't we? Yes. We PAY to do it.
