"AREN'T YOU GONNA say hello?" asks the mega-frightening Pennywise the Dancing Clown (Tim Curry) when he first appears in ABC's 1990 adaptation of Stephen King's It. The story about the shape-shifting cosmic creature who devours children and the group of friends who defeat him twice, as kids and as adults-is an iconic horror tale. And yet, after 32 installments of The Simpsons' annual Halloween treat, "Treehouse of Horror," it's one that had yet to be parodied when episode writer Cesar Mazariegos pitched it. "We all looked at each other and were like, 'How did we not ever do It?'" he recalls.
