Fat Butt and Pancake Head/Trivia

Trivia

 * Scott Tenorman and Shelley Marsh can be seen at the beginning watching Kyle's presentation.
 * A Phil Collins poster can be seen in the room where Cartman and Lopez sign up to create a music video.
 * In the beginning at Kyle's presentation, Ruby Tucker can be seen in two places at once
 * The episode title is a parody of the show Beavis and Butthead, and Trey Parker and Matt Stone are fans of the show and the creator Mike Judge has done a couple of roles on South Park, including the voice of Kenny as he says goodbye in the film South Park: Bigger, Longer & Uncut. Another explanation for the episode title is Ben Affleck has a notoriously flat head (like pancakes).
 * Jennifer Lopez's (the hand puppet) conversation with Kyle in the mall has dialogue borrowed from a scene from the 1979 film The In-Laws.
