Other mistake: When the escaped convict takes Barney hostage, they walk away from the lake and Barney drops the piece of paper with the convict's picture. Later, when Andy walks across the grass he finds Barney's cap and the paper lying on the grass, but the problem is that Andy needs to pull up at the center of the paper because it's pinned to ground, presumably so it wouldn't move or blow away for the shot.

Continuity mistake: When Opie surprises Andy by telling him that he wants to take piano lessons with Clara, he heads to the piano to play what he already knows, and when Opie plays Chopsticks on the piano he's wearing a different shirt.

Andy: Clara, sometimes a parent can't see what he should do, and sometimes it takes a person from the outside to show him. And I'd like to thank you.
Clara: Groovy.
Trivia: When Gomer and Barney are waiting at the Miracle Salve Co. Office, Barney speaks in a nasally high pitch voice. When Gomer asks Barney what's the matter with his voice, Barney explains that he's been talking like that as a disguise, to which Gomer asks, "How do you do that? I wish I could do my voice like that!" Jim Nabors does precisely that for his role as Gomer.
Question: Who was Ralph Henderson?





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.
