Earning the series' highest ratings, the third season opened with the landmark "That's My Boy?" about Rob's fear that he's brought the wrong baby home from hospital, getting the longest studio audience laughs in the show's history. Thirty-One Original Full Length Episodes including the hilarious "October Eve" (Laura is mortified when a nude portrait of her surfaces in a New York gallery) and "Big Max Calvada"(a gangster muscles Rob, Buddy and Sally into writing a comedy routine for his nephew).
