Michael Richards played the role of the "World's Greatest Janitor and TV Star" in the excellent film UHF. The character's name was derived from Stanley Snedowski who is one of the owners of The Bottom Line which is one of Weird Al's favorite venues to play in New York.
Stanley Spadowski has a pronounced overbite while Michael Richards does not. This was accomplished with some fake teeth which were made for Michael by a dentist friend of his in London. Richards brought the teeth with him to his audition for the part and they became crucial to his portrayal of the character -- so much so that he was quite upset when he forgot to bring them for one of his scenes.
