Remember the Simpsons, that late night sitcom on Fox? Well, before the first episode premeired, Matt Groening decided to make the episode before they aired it. When they watched the episode, weird things started to happen. First, Krusty was acting like Sideshow Bob. He stabbed Bart 2 times and threw him off a cliff. Then, Krusty got Sideshow Mels bone and hit him. Blood was everywhere. Then, it ended. Matt was upset that that scene was there. So he told Fox to cut it out, and the Pilot episode aired on Fox a few months later.
