The school's seventh - and last - appearance was in "Bwah My Nose". The school is armed with guards who protect the area. It is unknown who the principal of the school is although it is sometimes suggested that might be Prinicpal Moss of Tom Landry Middle School, such as in the episode, "Care-Takin' Care of Business" when he tells Smithy that he will make sure that Smitty gets a bonus added to his pention. However this was condradicted in the earlier episode, Kidney Boy and Hamster Girl: A Love Story, when an unnamed principal appears at the high school pep-rally as well as some other appearances throughout the episode. This is, however the only time there was a principal at Arlen High, leading to the suggestion that he may have been fired at some point shortly after with Moss serving as an interim principal seeing as the episodes take place fairly close to each other.
