South Park Episode 613 - "The Return of the Fellowship of the Ring to the Two Towers"
The boys are on a mission: return "The Lord of the Rings" to the Two Towers Video Store in Conifer.
But this is no ordinary copy. Butters, the evil sixth graders, and the boys' parents all try to steal the ring, er tape, from the boys. Will they succeed? What do you think? J.R.R. Tolkien must be spinning in his grave.
