“The Simpsons” is planning to kill off a character during the show’s 26th season, and executive producer Al Jean is warning the death will be permanent, reports the Los Angeles Times’ Show Tracker.

“When we kill [a character], they stay dead,” Jean said in a conference call with reporters. The death will occur in the episode “Clown in the Dumps,” which will air Sept. 28.

The comment comes after the Fox animated show “Family Guy,” which airs in a block with “The Simpsons,” killed off Brian, the family dog, only to bring the character back a short time later, the piece notes.

“We gave [the episode] that title for a reason,” Jean said. “Some people have guessed it correctly and some people are really, really off.”

In the episode Krusty the Clown gets offended at a celebrity roast in his honor, and decides to retire from show business. It will feature the voices of Sarah Silverman, David Hyde Pierce and Jeff Ross.

Jean also mentioned that he has no idea how much longer the show will continue to run, although he added, “At least two more years.”

He continued, “Probably four, maybe more. Nobody has talked to us about wrapping it up.”
