Predictably, chaos ensues. But the twist is that the hypnosis works —sort of. Most of Springfield buys into the cheerful delusion, leading to a series of wonderful visual gags (Moe giving away free beer “for Santa,” Chief Wiggum trying to arrest the North Pole). The real story, however, belongs to two characters: and Professor Frink .

Stick around through the credits for a post-credits scene where Santa Flanders (still hypnotized) delivers a lump of coal to Elon Musk’s Mars colony. It’s the most 2024 joke in the episode, and it’s worth the wait.

Where the episode truly shines is in its handling of Ned Flanders. For years, Flanders has been a punchline—the overly cheerful, diddly-loving neighbor. Here, he is given dramatic weight. When Ned discovers the town’s belief in him as a saint is based on a trick, he doesn’t get angry. He gets sad . In a quiet, devastating scene set in an empty church, Flanders admits to God that he’s tired of being “the nicest guy in the world” if no one believes in him for real. The episode doesn’t mock his faith; it interrogates it. A montage of Flanders trying to lose his temper (failing adorably) and then sinking into a silent, cocoa-less depression is some of the best character work the show has done in a decade.
