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 KingWe live in a society now where the sexual taboo for children has really passed by the wayside. Any nineyear-old can go into a 7-11 and check out the Playmate of the Month, but you don't want your kids to know about death. You don't want your kids to know about disfigurement. You don't want 'em to know about creepy things because it might warp their little minds.
Stephen KingThe idea for each of the stories in this book came in a moment of belief and was written in a burst of faith, happiness, and optimism. Those positive feelings have their dark analogues, however, and the fear of failure is a long way from the worst of them. The worst - for me, at least - is the gnawing speculation that I may have already said everything that I have to say, and am now only listening to the steady quacking of my own voice because the silence when it stops is just too spooky.
