Principal Sauerbraten is the principal of Gallaghar Elementry School. When Numbuh 4 landed on the basketball court and salad dressing came up, he was ordered by Principal Smelling to have children drill for a larger reserve so that the other school's principals can know what he was talking about. When Principal Smelling's plan failed, he landed his fork on the controls Numbuh 1 dropped and the school was covered in salad dressing.
In real-life, forcing children to carry out such labor would lead to a massive child labor dispute with the government, likely going all the way to the Supreme Court.
Principal Sauerbraten is a parody of Colonel Klink from Hogan's Heroes.
