The series revolves around
Andy Taylor (
Andy Griffith), the sheriff of the sleepy, slow-paced, fictional community of
Mayberry, North Carolina. His laid-back but level-headed approach to law enforcement makes him the scourge of local
moonshiners and out-of-town criminals, while his abilities to settle community problems with commonsense advice, mediation, and conciliation make him popular with his fellow citizens. His professional life, however, is complicated by the repeated gaffes of his inept deputy,
Barney Fife (
Don Knotts). Barney is Andy's cousin and best friend. At home, widower Andy raises his young son
Opie (
Ronny Howard), assisted by his maiden aunt and housekeeper,
Aunt Bee (
Frances Bavier). Opie, though generally respectful and well-behaved, is also curious and adventuresome and tests his father's parenting skills. Aunt Bee, meanwhile, is a wonderful cook and housekeeper, but her ill-considered romances and occasional quirks cause her nephew concern. Andy's friends and neighbors include, at various times, barber
Floyd Lawson (
Howard McNear;
Walter Baldwin portrayed the role in the 1960 episode "Stranger in Town"), service station attendants and cousins
Gomer Pyle (
Jim Nabors) and
Goober Pyle (
George Lindsey), and local drunkard
Otis Campbell (
Hal Smith). There are two mayors over the course of the series: Mayor Pike (
Dick Elliott) is more relaxed, but often indecisive, while Mayor Roy Stoner (
Parley Baer) has a more assertive personality. Other semi-regulars include townswoman
Clara Edwards (
Hope Summers), Barney's sweetheart
Thelma Lou (
Betty Lynn) and Andy's schoolteacher sweetheart
Helen Crump (
Aneta Corsaut). Ellie Walker (
Elinor Donahue) is Andy's girlfriend in the first season, while Peggy McMillan (
Joanna Moore) is a nurse who becomes his girlfriend in season 3. In the color seasons, County Clerk
Howard Sprague (
Jack Dodson) and handyman Emmett Clark (
Paul Hartman) appear regularly, while Barney's replacement, Deputy
Warren Ferguson (
Jack Burns), appears in about half of season six.
Ernest T. Bass made his first appearance in episode 94 ("Mountain Wedding"), as well as four later episodes. The actor who portrayed him,
Howard Morris, also played George, the television repairman in episode 140 ("Andy and Helen Have Their Day") and two uncredited voice roles, as Leonard Blush and a radio announcer. Morris also directed a total of eight episodes of the show, none while portraying Ernest T. Bass.
Unseen characters such as telephone operator Sarah, and Barney's love interest, local diner waitress Juanita Beasley, as mentioned in the first season, are often referenced. The show's announcer for the first five seasons, Colin Male, portrayed Game Warden Peterson in episode 140 ("Andy and Helen Have Their Day"). In the series' last few episodes, farmer Sam Jones (
Ken Berry) debuts and later becomes the lead of the retitled show,
Mayberry R.F.D. Don Knotts, Aneta Corsaut, Jack Dodson, and Betty Lynn also appeared on Griffith's later show,
Matlock. ==Episodes==
