"Treehouse of Horror XIII" is the first episode of the fourteenth season of the American animated television series The Simpsons, and the thirteenth Treehouse of Horror episode. It first aired on the Fox network in the United States on November 3, 2002, three days after Halloween. It is the second Halloween episode to have a zombie related segment, and the last Halloween to have three separate writers credited for writing three stories (starting with "Treehouse of Horror XIV", only one writer is credited for writing the three stories). It is also the first Halloween episode to be titled Treehouse of Horror in the opening credits, as all prior Halloween episodes were referred to as The Simpsons Halloween Special. In the episode, Homer buys a magic hammock that can create duplicates of anyone who lies in it in "Send in the Clones"; Lisa's call to end gun violence resurrects undead outlaws in "The Fright to Creep and Scare Harms"; and Dr. Hibbert invites everyone in Springfield to his island resort where everyone is turned into half-man, half-animal hybrids in "The Island of Dr. Hibbert".

Disregarding this, Homer lies down and discovers that the new hammock can produce clones of anyone who rests on it. He inspects the first clone and notices that it does not have a belly button. He makes clones to do all of his chores, which include fixing a light fitting (resulting in the first clone being electrocuted to death and Homer creating a new clone to help dispose of the body), helping Marge choose an outfit, visiting Grampa, and play baseball with Bart, Lisa and Maggie. He also discovers that the clones are becoming increasingly less intelligent. When one clone kills Ned Flanders, Homer decides to
