This year's Treehouse of Horror episode of The Simpsons will see Sideshow Bob finally kill his longtime nemesis--no, not unfortunately placed rakes--but Bart Simpson.

　　Finally In the 25 years of The Simpsons, Sideshow Bob has tried to kill Bart on a number of occasions, but his attempts are always derailed at the last moment.

　　But not this time.

　　The Simpsons executive producer Al Jean revealed the news this week during the ATX Festival, attended by Entertainment Weekly. He didn't say how Sideshow Bob will do away with Bart, but explained that after he does, he will be faced with another challenge: finding out what to do after his life's work is completed.

　　Jean said he hates "frustration comedy," and always wanted to see the Coyote kill the Road Runner from Looney Tunes. "So we'll scratch that itch" with The Simpsons, he said. The episode will air this fall.

　　History shows us that Bart will return after his death in this episode.

　　Treehouse of Horror episodes basically exist as one-offs, which has allowed the show to do all kinds of crazy things in the past, including killing off characters who later return.

　　In other recent Simpsons news, the show has been renewed for two more seasons, although Mr. Burns may not be a part of it them. The show's producers also recently said that it's unlikely that a Simpsons Movie sequel will be made anytime soon.
