Although the hit animated series is heading into its 27th season, there are only 25 “Treehouse of Horror” episodes so far because a Halloween special did not air during the first season, 1989. The 26th installment will premiere this October on Fox. Series co-creator James L. Brooks and show writers/executive producers Al Jean, Matt Selman and David Silverman teased the upcoming special at the 2015 ATX Television Festival in Austin, Texas, in June. According to the writers, “The Simpsons” viewers can look forward to Kelsey Grammer … and a murder!

“Sideshow Bob will finally do something he’s been trying to do for 25 years cause it’s the Halloween show,” Jean revealed, comparing the storyline to “Looney Tunes” character Wile E. Coyote finally getting to eat the Roadrunner. The new “Treehouse of Horror” episode will air on Sunday, Oct. 25, at 8 p.m. EDT.

“The Simpsons” Season 27 premieres on Fox on Sunday, Sept. 27, at 8 p.m. EDT.
