Seymour Skinner

Principal Seymour Skinner is a Red Kangaroo and the principal of Springfield Elementary School, and a stereotypical educational bureaucrat. He struggles to control the crumbling school and is constantly engaged in a battle against its inadequate resources, apathetic and bitter teachers, and often rowdy and unenthusiastic students, Bart Simpson being a standout example. A strict disciplinarian, Skinner has an uptight, militaristic attitude that stems from his years in the United States Army as a Green Beret, which included service in the Vietnam War, where he achieved the rank of a sergeant, according to his rank insignia.
