Movementarians

The Movementarians was a villainous cult which appeared in The Simpsons' episode The Joy of Sect.

They are first seen on the Springfield airport inviting people to spend a free weekend on their community center, during which they convince them to give up on their properties and join the Movementarians to work in their community farm, with the help of brainwashing films, songs, group therapy sessions, low-protein gruel, and the promise of taking them to the planet of Blisstonia in a spaceship which is kept inside the forbidden barn. The head of this organisation is a mysterious man known as "The Leader", who is responsible for the spaceship and the mission involving it.

When the Simpson family moves to the Movementarian center, Homer is the only one of them convinced, but eventually the kids are converted as well. Marge bravely escapes and recruits Reverend Lovejoy, Groundskeeper Willie and Ned Flanders to help her rescue and de-programme her family. Once they are back to normal, Homer returns to the farm to show the movementarian community there is nothing in the forbidden barn, but it turns out there actually is a spaceship on the inside. However, as it flies away while the Leader tells Homer that his lack of faith has doomed mankind, its outer layer falls apart revealing a human-powered helicopter which the Leader is using to take all the money with him, but it quickly crashes down onto Cletus' house, who takes the money by threatening the Leader with a shotgun.
