I Won't Be Home for Christmas is the ninth episode of Season 26. It aired on December 7th, 2014. This is the 17th Christmas special (with only one short and 16 Christmas episodes) of the series.
Marge kicks Homer out of the house after Moe convinces him to stay out all night on Christmas Eve at his tavern. Depressed, Homer takes a lonely walk through Springfield instead of being with his family.
Homer plans to fulfill Marge's wish of leaving work on time and arriving home to celebrate Christmas with his family. However, he stops on the way home for a drink at Moe's, and when he says it's time for him to get home Moe convinces him to stay out all night on Christmas Eve when Moe admits to being lonesome and depressed. Homer loses track of time and when he finally gets home, Marge is enraged at Homer and kicks him out, saying she does not want him in the house on Christmas.
Homer then goes on an odyssey through a deserted and chilly Springfield, with Moe compounding his sadness by avoiding him when Homer shows up to try and talk to him (and to add insult to injury, Homer's car gets towed with his cell phone frozen inside it).
When Marge tells Bart and Lisa she is not inclined to forgive Homer, Moe climbs down the the family's chimney and explains to Marge that he was the reason why Homer was out late on Christmas Eve. Marge tries to call Homer, but because he lost his phone, she goes out to look for him. Homer goes to the local movie theater to watch a depressing Life is Beautiful-type of film around other lost souls. After Marge searches through the city and Homer ends up at a depressing party for mall workers, they each have epiphanies: Homer says that being without his family at Christmas is much worse than being with them, and Marge says that she shouldn't always assume Homer is performing stupid achievements for no reasons. The two finally reconcile and look forward to a happy new year.
