Did anyone else notice that the military guy claimed that Cartman "Didn't exist" despite the fact that Cartman has already made quite a bit of news in the South Park universe? After all, he has been labeled the "Finaicial Genius of our time" in the amusement park episode, and even got a "freaken medal" for discovering how to shove food up his ass.
I'm sure he's been on a news some other times.
