"The Nightmare After Krustmas" is the tenth episode of the twenty-eighth season of the animated television series The Simpsons, and the 606th episode of the series overall. It aired in the United States on Fox on December 11, 2016.

At the First Church of Springfield, very few people are present at Reverend Lovejoy's service at the fourth Sunday of Advent and his wife Helen calls him afterwards to meet a "fan club" which was actually an intervention by Ned Flanders, Agnes Skinner, Sideshow Mel and Lovejoy's boss The Parson (a caricature of Bing Crosby) who introduce him to the Patriarch. They tell him he needs to bring more people to the church, and he assures them he's going to do so because Springfield is a good Christian community.

Meanwhile, a pagan festival is held in town, with the Simpson family and the others attending where Theo Jansen shows his feature attraction the Strandbeest, a wind-powered vehicle.

However, the Strandbeest goes wild due to the stronger winds and tramples Krusty the Clown, who was ice-skating with his daughter Sophie, whom he only sees during the holidays. At Springfield General Hospital, Krusty (who's Jewish) tries to bond with his daughter but finds out her mother raised her Christian and she wants to celebrate Christmas. Seeing the discomfort, Marge invites the pair to spend Christmas with them.

Back at home, Marge brings Maggie a Gnome in Your Home (a parody of The Elf on the Shelf), a gnome that is supposed to watch over her all the time and tell Santa Claus what she's been doing, He doesn't sleep and never shuts his eyes and Homer tells her that if she isn't good, he'll nibble off her fingers. Krusty arrives at the home but brings in a TV crew to record it as a television special, angering Sophie to the point of sending him away.
