God's Army (2000)
Flashbacks taken from Dutcher's earlier film as stock footage.
Jonathan invites neighbor Wes (Richard Dutcher, also the director and star of "God's Army") to come in and watch the movie, but he declines, saying that "the toilet scene is kind of offensive."
Jonathan and his friends watch this movie on his TV after the "Preference" dance.
When Jared goes to the movies, there is a movie poster behind him for God's Navy.
