Sideshow Bob will kill Bart during ‘The Simpsons’ Halloween episode

This year's 'Treehouse Of Horror' episode will also feature the return of 'Spider-Pig'

Sideshow Bob will finally kill his longtime nemesis Bart Simpson during this year’s Halloween episode of the long-running animated sitcom.

Because The Simpsons‘ annual ‘Treehouse Of Horror’ Halloween special takes place outside of the show’s normal continuity, Bart will only remain dead for the duration of the episode. However, executive producer Al Jean promised fans that the episode will offer a glimpse of what life would be like for Sideshow Bob – who is voiced by former Frasier star Kelsey Grammer – once he has finally exacted his revenge on The Simpsons’ eldest child, who famously foiled his plan to frame Krusty the Clown for armed robbery in Season One.

“I hated frustration comedy so we’ll scratch that itch,” Jean told Entertainment Weekly, also revealing that Spider-Pig, a popular character from 2007’s The Simpsons Movie, will make a comeback appearance in the Halloween special.

The Simpsons has recently been renewed for another two seasons. Fox announced in May that it has ordered Seasons 27 and 28 of the long-running animated sitcom, which will take The Simpsons to a massive 625 episodes since it began in 1989. The show is already the longest-running American sitcom, the longest-running American animated programme and the longest-running American scripted primetime series of all time.

Season 26 of The Simpsons drew to a close on Fox on May 17. Season 27 will then begin on Fox this autumn, with Lena Dunham guest starring in the Season 27 premiere accompanied by her Girls castmates.
