And the one with Barney singing off key in the choir.
That is a good one. In the end, I think the Andy Griffith show and Gomer Pyle show both ran episodes where the plot was someone losing their voice, Barney on AG and Sgt. Carter in the Gomer Pyle show and Jim Nabors, with that voice of his, sang while Barney and Carter mouthed the lyrics. Something of that nature but both shows did it.
The episode with Aunt Bee’s pickles was a good one.
