South Park: The Ungroundable

"The Ungroundable" is the 14th and final episode of the 12th season of the animated series South Park, and the 181st episode of the series overall. It originally aired on Comedy Central in the United States on November 19, 2008. The episode spoofs vampire films including the Twilight craze and The Lost Boys, where Butters believes that he sees vampires in the school. The head "vampire" often says "per se" which seems to be a reference to an episode of Tyra that deals with vampires, in which one of the vampires frequently says "per se".
