Treehouse of Horror XXXVII aired on Fox on Sunday, October 25, 2026, and by Monday morning the internet only wanted to talk about one sign. Fair enough, the sign is great. But the episode around it is a solid Halloween special with three very different stories, a stop-motion intro, and a couple of fun guest stars. Here is the whole night, segment by segment.
Before the stories start, the episode opens with a stop-motion intro that pays homage to The Nightmare Before Christmas. It is a lovely fit: the Simpsons' Halloween specials and Tim Burton's film come from the same tradition of spooky stories played for warmth as much as scares. Guest stars across the episode include Jeff Probst and Tiffany Haddish.
Segment 1: "Bride's Shed Revisited"
The first story centres on Marge and a magical shed. The shed swaps Marge's husbands, which is the kind of premise only a Treehouse of Horror episode can carry with a straight face. One husband is a problem. A shed that keeps exchanging him for different versions is a much bigger one, and Marge is left managing the rotating results.
It is a relationship comedy wearing a Halloween costume, which has always been one of the special's favourite modes. The magic is the excuse; the marriage jokes are the point.
Segment 2: "Dog Boy Afternoon"
The second segment, its title playing on the film Dog Day Afternoon, switches Bart and Santa's Little Helper into each other's bodies. Bart gets the dog's life: food in a bowl, naps, zero homework, but also zero ability to tell anyone what happened. The dog, meanwhile, inherits Bart's body and Bart's problems, which turn out to be wildly unsuited to a greyhound's temperament.
Body-swap stories live or die on the small details, and this one has a good engine: each half of the swap looks like an upgrade until it very quickly is not. It is the lightest of the three stories and the one most aimed at younger viewers.
Segment 3: "Vehicular Dadslaughter"
The final segment is the one producing all the screenshots. Bart and Lisa break into the Springfield DMV at night, and the office is not what they expected. It is run by witch versions of Patty and Selma, and the department has been rechristened the Department of Magical Vexation, also readable as Damnation Most Vile. Inside, they find Homer, who has been trapped there starring in driver-education films, a fate arguably worse than anything the witches had planned.
And outside the building stands the sign: "VISIT OUR WEBSITE AT our-website-is-broken.org". If you somehow arrived here without seeing it, our homepage guide to the broken website sign explains the gag and what the real address does, and we gave the moment its own deep dive in the DMV sign gag, explained.
How the three fit together
The running order is smart. The shed story is the weird one, the dog story is the sweet one, and the DMV story is the one built to be quoted, screenshotted and shared. That is a pattern the later Treehouse of Horror episodes have leaned into: at least one segment designed around a single image that can escape the episode and live on social media by itself. This year, the image escaped so completely that many people sharing it had not watched the episode at all.
The DMV choice helps. Unlike a haunted house or a cursed object, a motor vehicles office is a horror every adult has personally survived, which is why the segment and its sign work even as a single still frame. We wrote more about why jokes at the expense of government websites are basically immortal in our look at the Simpsons' website gag tradition.
The verdict
Treehouse of Horror XXXVII is a strong entry in the modern run: a stylish stop-motion intro, three distinct segments, game guest stars, and one background sign that will probably outlive everything else in it. If you only watch one part, watch the third segment. If you watch the whole thing, keep your eyes on the backgrounds. In Springfield, that is always where the truth is written. Usually on a sign. This year, the sign was about a website, and the website, true to its word, is broken.
