This is my favorite episode of one of my favorite shows of all time. The look on Barney's face when he hears "his" voice through the microphone is classic! In my opinion, the TV character 'Barney Fife' is the best TV character of all time, followed by Peter Falk's 'Columbo', John Ritter's 'Jack Tripper', Michael Richard's 'Kramer', and Carrol O'Connor's 'Archie Bunker'. Good stuff here. Barney sings in the Mayberry choir and during practice, John Masters, the choir director notices someone singing off key. Barney offers to help John locate the person, but everyone soon realizes that it is Barney himself. Not wanting to hurt Barney's feelings by kicking him out of the choir, John and Andy try to figure out how to get around the sticky situation. They try practicing at different locations without making Barney aware of where the practices are, but when that doesn't work, Andy decides it would be best to make Barney the soloist- only unbeknown-st to Barney, he would be singing into a dead microphone in a very "soft" voice. Andy tells Barney the microphone will amplify his voice a "thousand" times and that Barney must sing with almost making no sound to keep from busting every ear drum. The plan works when a bass soloist sings into a live microphone backstage, making Barney think the loud deep voice is his own. Classic television!
