The Taylors in Hollywood - S6-E8
Revealing mistake: While Andy, Aunt Bee, and Opie are at the Hollywood studio watching a scene being filmed, when Andy mistakenly stands up and interrupts the filming we can see the wall and shelves behind the director, and it should look familiar because it's the wall and shelves from Floyd's shop in Mayberry.
Answer: In S3 x E11 Convicts-at-Large, there is a character named Big Maude Tyler, who is the leader of three female escaped convicts. Andy listens to the radio as the news announcer says that Big Maude's aliases include Clarice or Annabelle Tyler and also one amusingly named Ralph Henderson.
