Our favorite episode is the one with Barney singing in the choir..... or TRYING to sing in the choir. Andy gets this great idea to have him sing a solo, but makes him sing really quiet because of the microphone being so powerful (wink, wink). The solo is being sung from behind the curtain by Bert Mustin.
Barney in the choir is an alltime classic. One of the funniest things EVER on television.
Aunt Bea on the pickle-making binge was hilarious, too. In my mind's eye, I can still see Barney stopping cars heading out of town, and making them take a jar of pickles with them.
Another Aunt Bea classic moment was when the elixir salesman came to town, and the whole Ladies Aid Society got plowed in the parlor.
They just don't make em like that anymore.
