My favorite episode is where the harried big-city businessman gets stuck in Mayberry on a Sunday when his car breaks down. At first, he's infuriated that nobody will fix it so he can get moving - - but gradually the kindness and relaxed pace of the small town wears away his gruffness, and he starts humming along with the hymn-singing on Andy's front porch.
And they are all sitting on the front porch on Sunday after lunch when Barney stretches, leans back and says: "You know what I'm gonna do?"
Andy: "Hmm?"
Barney: "I'm gonna go home, take a nap, go over to Thelma-Lou's and watch a little TV."
Andy: "Huh".
Barney (after a pause): "Yep, that's the plan."
Andy: "What?"
Barney: "Go home, take a nap, go over to Thelma-Lou's and watch a little TV."
Andy: "Hah".
Barney: "Yeeeeeppp! Go home, nap, Thelma-Lou's for TV."
Andy: "Huh"
Mr. Tucker: "For Pete's sake go, go, go do it. Go home, go to Thelma-lou's, go!"
Barney (stomping off): "What's the rush?"
"Man in a Hurry" ... great one.
