• Actor Allusion: As Warren, Jack Burns would occasionally use his stand up trademark of making a statement to another character then saying "huh?" "huh?" "huh?" until then when the other character shouts an agreement with him to get him to shut up.
  • The Danza: Andy Griffith as Andy Taylor and Elinor Donahue as Ellie Walker.
  • Hey, It's That Guy!: Lot of guest stars, though this troper remembers Lee Van Cleef in a very small role as--surprise--a bad guy in the carnival episode.
    • A then-unknown Jack Nicholson is also in some brief scenes in one of the later episodes.
  • Name's the Same: In the episode "The Bookie Barber", there is a resident of Mayberry named Emma Watson.
  • The Other Darrin:
    • Ben Weaver, the department store owner, was played by three different actors over the course of the show.
    • Four different actors played Wally, the owner of the filling station.
