Show me someone who actually likes clowns and I'll show you a liar. One of the best running jokes on Modern Family is Cam's alter ego Fizbo, who makes just enough appearances not to terrify (just). And the head honchos over at the show clearly agree, cobbling together footage from the show and turning it into a horror trailer that has all the hallmarks of a genuine slasher flick. This makes the idea of "sleep clowning" all the more terrifying. Good luck sleeping after watching this.
