Twenty-five years ago, Robert Werwilliger swore he'd exact revenge against Bart Simpson. This fall, after numerous attempts, he'll finally succeed.
According to Entertainment Weekly, Kelsey Grammer will return this fall for "The Simpsons" Halloween special, in which Sideshow Bob will -- at long last! -- kill Bart. Executive Producer Al Jean compared Bob's quarter-century quest to Wile E. Coyote's never-enduring pursuit of the Road Runner, saying, "I hated frustration comedy so we’ll scratch that itch."
Of course, the Halloween episodes aren't exactly canon, so Bart won't be joining the likes of Bleeding Gums Murphy and Maude Flanders any time soon.
The upcoming 27th season will also see the return of Spider-Pig, aka Plopper, which made his debut in 2007 in "The Simpsons Movie."
