Bobby's (Michael Lookinland) job as safety monitor at school turns him into a fascistic stickler for the rules. Donning his safety monitor sash, he is soon turning his classmates in for such major infractions as chewing gum and running in the hallways. Ironically, this includes sister Cindy (Susan Olsen) who suffered her own bout of big head-itis in "The Tattle Tale." Then, caught up in his dweeby ideological fervor, Bobby brings his job home, ratting out his brothers and sisters for every forgotten curfew and chore. Finally, "by-the-book" Bobby must ignore a "No Trespassing" sign to save a classmate's kitten trapped in a condemned building. Mussing his best blue suit in the process, he attempts to clean it before anyone finds out that he broke a rule -- soaking the laundry room in an tidal wave of soap suds.
