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.Super Grover
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.Super Grover
Question: Beginning with the "Convicts at Large" episode in season 3, full width window boxes appear at the bottom of both front windows on the inside of the Sheriff's Office. Prior to this episode, they did not exist. Window boxes are often used to display decorative plants but I don't see any plants. And if they were supposed to partially block the background, the blinds were long enough to accomplish that. I find it hard to believe that the producers would spend additional money (for material and labor) for something that seems to serve no purpose. So why were they added?
