|“||This ain't a girl scout camp.||„|
|~ Mr. Sir's catchphrase.|
|“||You take a bad boy, make him dig holes all day in the hot sun, it turns him into a good boy. That's our philosophy here at Camp Green Lake.||„|
|~ Mr. Sir to the prisoners.|
Mr. Sir (real name: Marion Sevillo in the film) is the secondary antagonist of Louis Sacher's 1998 novel Holes, as well as its 2003 Disney film adaptation of the same name.
He is the chief officer at the boys prison camp, Camp Green Lake which puts him in a very high position of power with the only person above him being the warden. He always has an angry attitude due to his withdrawal of alcohol and tobacco, and may be totally mentally unstable. He doesn't get along with anybody, not even Mr. Pendanski, the camp members, or the Warden however he does seem to have a sense of humour. He carries a pistol, which he uses to defend himself (and on one known occasion, Stanley Yelnats, the story's main protagonist) against the deadly yellow-spotted lizards. His fate differs in the book and movie: in the book, he simply gives Stanley his backpack after the latter is cleared of all charges, while in the movie, he is revealed to be a criminal who violated his parole by carrying a pistol (the policeman who originally arrested him happened to conveniently be at the camp and recognized him) and is arrested. In the latter ending, the officer reveals that Mr. Sir's real name is Marion Sevillo, much to the amusement of the campers.
He has a habit of saying "this ain't a girl scout camp." Ironically, Camp Green Lake becomes a girl scout camp after the Warden loses ownership of the property. He also took to eating sunflower seeds to compensate for his lack of cigarettes, though he started smoking again near the end of the book and movie because sunflower seeds "didn't work for him."
