As well as being fat and obnoxious, Madman sports a hairstyle and mustache noticeably similar to that of Adolf Hitler.

Principal Sam Madman is an antagonistic character from Whatever Happened to... Robot Jones? He is the schoolmaster of the educational facility attended by Robot Jones, and often acts cruelly towards Robot due to his fear and hatred of sophisticated technology. Madman is not only technophobic, regarding machinery as "rubbish" in the pilot episode, but he is also immature and tyrannical towards his students, and treats his staff quite harshly as well.
