Season 5 marked two notable lasts for this beloved series, which never fell below the Top Seven in the ratings. This was the last season in black and white. More devastating, it was multi-Emmy-winner Knotts' last season as Barney Fife. By the penultimate episode, "Opie and the Carnival," he is just gone, an unceremonious departure for an iconic character so integral to the show's success. That "Banjo-Playing Deputy" in the season finale is Jerry Van Dyke, who might have been a worthy replacement for Knotts. Instead, he reportedly turned down the role to star in his own sitcom, My Mother, the Car. The rest is TV infamy. By this time, though, The Andy Griffith Show's best years were behind it. But this season contains at least two classics, "Goodbye Sheriff Taylor," in which Barney is sheriff for a day while Andy interviews for a job in Raleigh, and "The Case of the Punch in the Nose," in which Barney reopens an unresolved 1946 case involving Floyd the Barber and Charley Foley. And with episodes featuring the late Howard Morris' Ernest T. ("The Education of Ernest T."), the Darling family ("The Darling Baby"), Mt. Pilot "fun girls" Skippy and Daphne ("The Arrest of the Fun Girls"), and a guest star turn by Don Rickles ("The Luck of Newton Monroe"), Andy Griffith Show devotees are advised to take the Fifth. --Donald Liebenson
