Stuart Besser (Rodger Bumpass) - Mr. Stuart Besser is the incompetent principal of the school. Noted for his stupidity and overweight stature, he is often satirized, whether it be vocal or written, by his students. His negligence and ignorance serves as recurring comic relief within the television show. Mr. Besser was once married to Vinnie's aunt, much to the shock of both males (Vinnie didn't know Mr. Besser was his aunt's husband and Mr. Besser didn't know Vinnie is his wife's nephew until the two of them met during the wedding party), but the wedding ended when she learned he expected to live at her expenses. Mr. Besser was oblivious to the fact Vinnie didn't like being his nephew.
