All About Mormons

"All About Mormons", also known as "All About the Mormons?", is the 12th episode of the seventh season of the American animated television series South Park and the 108th overall episode of the series. It was originally broadcast on Comedy Central in the United States on November 19, 2003. The episode revolves around the religion and culture of Mormons, as a Mormon family moves to the town of South Park and influences the beliefs of the family of character Stan Marsh. The story of Joseph Smith's founding of Mormonism and the origin of the Book of Mormon is told through a number of comedic 19th-century flashbacks, with a musical narration.

The episode was written and directed by series co-creator Trey Parker, and it was rated TV-MA in the United States. The episode evolved from personal experiences of creators Parker and Matt Stone, who grew up in Colorado. Growing up in Colorado both Stone and Parker often visited Utah, and both had Mormon classmates. The scene in which Stan is invited to dinner by the Mormon family was inspired by Parker's first girlfriend in high school, who was Mormon and invited him over for Family Home Evening. They found the religion ridiculous but hard to parody due to the good-natured attitudes of many Mormons.

The episode received positive reviews from television critics, and it has been placed on "best-of" South Park lists. Parker found that younger audiences found the episode unfunny, but many of his Mormon friends found it hilarious. "All About Mormons" was released on DVD along with the rest of the seventh season on March 21, 2006. Parker and Stone later carried over many themes from the episode for their musical The Book of Mormon, which opened on Broadway in 2011.
