The Simpsons season 36

Conan O'Brien hosts the "series finale" of The Simpsons, in which the finale itself is generated by an AI machine called HackGPT. In the finale, Bart's 11th birthday approaches and he realizes that Springfield is changing around him: Principal Skinner leaves for Sacramento with Groundskeeper Willie, Mr. Burns passes away and his fortune is given to the power plant employees, Comic Book Guy and his wife Kumiko's baby is born, with John Cena assisting with the delivery, Moe's Tavern closes, Nelson's father and the real Seymour Skinner return, Krusty the Clown ends his show, and Chief Wiggum joins the Chicago Police Department, as well as various marriages and deaths. Bart gains sentience within the finale and tries to resist the changes.

The Simpsons go to a fancy resort intended for Springfield's elite for a vacation, thanks to Homer buying timeshares back when Marge was pregnant with Bart.

The Springfield Police Department unearths a coffin with two corpses in it that also contains a business card of Grampa Simpson’s from the 1980s during his brief stint as a private investigator.

A series of scary stories are prefaced by "Cottage of Terror", a Mexican-themed opening animated by Jorge R. Gutierrez:

• "The Information Rage": Bart and Lisa find themselves having to put their differences aside as built up political divisiveness and rage manifests as two giant monsters and it’s up to the Simpson siblings to save Springfield.
• "The Fall of the House of Monty": On the day after Thanksgiving, Victorian-era Mr. Burns becomes a victim of his own greed and cruelty as the dead workers from his corn syrup factory rise up and seek revenge on their former boss.
• "Denim": In a parody of Venom, Homer comes into contact with a pair of sentient extraterrestrial denim pants that quickly bond with him, only to refuse to leave him when he needs it the most.
