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.
Trivia: When Andy, Barney, the mayor, and Upchurch are at the courthouse with the plaster castings of the footprints, Upchurch has named the sets of prints "Able, Baker, and Charlie." The names "Able and Baker" are also the names of the two monkeys who were launched into space on May 28, 1959 in a Jupiter rocket.
