The fight scene between Cartman and Wendy, as well as the music, is a reference to the final boxing match from the film Snatch.

When Mr. Mackey arrives after the fight, Cartman's head is pointing towards the school building.

After the fight, the Brimmy periodically switches sides during angle shifts.
