The Simpsons: Season 13 (2001 - 2002)

"Treehouse of Horror XIII" finds Homer cloned; Dr. Hibbert turning the family into half animals; and Springfield invaded by zombie cowboys.

One morning, Homer Simpson (voice of Dan Castellaneta) decides he doesn't feel like giving his son Bart (voice of Nancy Cartwright) and his best friend Milhouse (voice of Pamela Hayden) a ride to school, which turns out to be a bad choice, since Bart ends up stealing a police car on his way to Springfield Elementary. Bart and his folks end up in front of the usually lenient Judge Snyder (voice of Harry Shearer), but at the last minute the judge goes on vacation, with the stern Judge Constance Harm (voice of Jane Kaczmarek) taking his place. Harm decides Homer and Marge (voice of Julie Kavner) have done a bad job of raising Bart, and orders the boy to be tethered to Homer at all times. This soon proves wildly impractical and Marge decides it isn't helping, so she cuts the cable. This angers Judge Harm, who responds by putting Homer and Marge in public stocks; they eventually escape, and Homer plots revenge against the judge, which typically goes awry. "The Parent Rap" first aired on November 11, 2001.

Ill-tempered bartender Moe Szyslak (voice of Hank Azaria) has been in even more of a funk than usual, and needing a reminder of what drew him into the mixed drink business in the first place, he heads back to the bartending school where he first learned his craft. Homer Simpson (voice of Dan Castellaneta) is put in charge of Moe's tavern while he's gone, which quickly becomes even more of a sinkhole on his watch. Upon returning, Moe decides his bar needs a makeover, and he transforms it into "M," an upscale nightspot for Springfield's most pretentious hipsters. Homer and his pals no longer feel welcome there at their regular watering hole, and he responds by setting up a tavern in his garage, using the legal loophole that he and his friends actually enjoying the facilities of their hunting club. Offended that his once-loyal customers are swilling beer somewhere else, Moe calls Homer on his ruse and insists that he and his pals actually go hunting for their Thanksgiving dinner. Featuring an appearance by R.E.M. (who appear at Homer's tavern under the mistaken belief they're playing an environmental benefit), "Homer The Moe" first aired on November 9, 2001.

Julia Louis-Dreyfus gives voice to a young woman wooed by Burns, who drafts Homer to help him cultivate a more youthful image.

A hypnotist unlocks a repressed memory in Homer, who recalls childhood times with Moe, Carl and Lenny---and his finding a corpse. Paul Newman and singer Judith Owen have voice cameos.

In this Christmas episode, Richard Gere offers Buddhist teachings to Lisa after she leaves her church because of Mr. Burns' tacky fund-raising efforts, which include commercials (during sermons) and podium-placed ads.

A social worker is assigned to try to bring the family together after police respond to a fight between Bart and Homer during a game of Monopoly.

Ben Stiller plays a sugar company's CEO who draws Marge's ire after Springfield is declared the "World's Fattest Town."

An(other) accident forces Homer's jaws to be wired shut, and improved listening skills result in a kinder, gentler---and more boring---Homer.
