Cosby - Season 1 Episode 11 Guard Almighty

Although Hilton thinks he's going to fight crime in his new job as a security guard, he ends up as a glorified doorman who gets more than he bargained for. After Hilton graduates at the top of his class in security guard training school, he is assigned to his post at a fancy apartment building and is ready to be a crime fighter. Although he quickly learns that the job requires many things not taught in class -- like dealing with precocious young children who won't leave the lobby and walking the tenants' dogs, his professional training comes in handy when a robber breaks into the building on the night of the World Champion New York Yankees celebration party, which is attended by manager Joe Torre and pitcher David Cone (guest starring as themselves) -- only after they prove their identity to the overzealous Hilton!
