"Treehouse of Horror VII" is the first episode of the eighth season of the American animated television series The Simpsons. It originally aired on the Fox network in the United States on October 27, 1996. In the seventh annual Treehouse of Horror episode, Bart discovers his long-lost twin Hugo, Lisa grows a colony of small beings, and Kang and Kodos impersonate Bill Clinton (voiced by Phil Hartman) and Bob Dole in order to win the 1996 presidential election.
This episode was written by Ken Keeler, Dan Greaney, and David X. Cohen, and directed by Mike B. Anderson. "The Thing and I" was written by Ken Keeler, "The Genesis Tub" was written by Dan Greaney, and "Citizen Kang" was written by David X. Cohen. Despite the similarities, "The Thing and I" was not based on the plot of the 1982 film Basket Case. The sequence where tiny spaceships attack Bart in "The Genesis Tub" marks one of the first uses of computers in The Simpsons animation. The computer was used to build models for reference and the animators later retraced it.
In 2017, IGN called "Citizen Kang" the best segment of the entire anthology, and placed the episode itself as number one in its ranking of all "Treehouse of Horror" episodes. The A.V. Club named Kang/Bob Dole's line, "Abortions for some, miniature American flags for others!", one of the best lines in the history of the show.
The ska punk band named I Voted for Kodos takes its name from Homer's line, "Don't blame me, I voted for Kodos", at the end of "Citizen Kang".
Kamala Harris quoted a line from "Citizen Kang" ("We must move forward, not backward; upward, not forward; and always twirling, twirling, twirling towards freedom") for a University of Chicago student scavenger hunt in 2013. A filmed clip of this moment was shown at the Simpsons panel during the 2024 San Diego Comic-Con, at a time when Harris was both the sitting vice president and the presumed Democratic presidential nominee.
Les Chappell notes that the episode is darker than previous Treehouse installments: Mature' is the wrong word, but there’s definitely an ambition here that hasn't been seen on Halloweens past, and a drive that would endure throughout the series long after the Clinton/Dole contest would fade from memory. As it enters its eighth year, The Simpsons proves it remains a force for comedic innovations, committed to moving forward, not backward; upward, not forward; and always twirling, twirling, twirling towards freedom."
