Season 36 of “The Simpsons” debuted Sunday night, and in the words of Gen Z: “It is so over.”

Viewers watching Sunday's 'The Simpsons' Season 36 premiere were told that it was the series finale — but it wasn't really the last episode.

Bart celebrates his 11th birthday with a party attended with many guest characters and extended cast members from across the series. Including John Cena, characters that have died, and others rarely seen such as Danny DeVito returning as Herb Powell for a single line.
