Some folks in Mayberry seem like they don't do ANYTHING for a living. They must have some source of income, though. And there are some very interesting occupations in The Friendly Town. Let's name the person and what they do for a living. If we don't know for sure we could mention clues as to what the occupation might be:
I'll start with an easy one:
Thelma Lou "works at the office."
Orville Monroe is an undertaker. (He used to repair TV's until I bought out that part of the business - but I didn't buy his delivery hearse vehicle.)
Freeburger: He was a Sewer inspector. He arrested Barney's father once. Andy said, "Maybe he was speeding in the sewer."
Andy also said that if you looked close enough, that Freeburger's badge had a little Manhole Cover in the center of it.
Ed had a refrigeration business.
Gomer discovered that Ed's Refrigeration serviced Aunt Bee's freezer on March 3, 1951.
Although he doesn't live in Mayberry, he has strong ties to someone who does: Aunt Bee's brother goes all around the world on a ship as a "Wiper." He just wipes and wipes. Something about a girl back in his home town. But we don't talk about that, don't you know.
And then there was "the man". He was the only person in a 50 mile radius that did refrigeration repair. Was "the man" Ed perhaps?
As Andy often says "Call the man!"
Then there was Malcom Tucker. He was in charge of Tucker Enterprises, and he was in a hurry.
Elmo ran the sporting goods/camera shop.
Aunt Bee also tried her hand as the co-owner of a Chinese restaurant. Things were going well until she took her fortune cookie fortune too seriously, so she sold out.
Aunt Bee got a job as a receptionist for a small printing firm that moved into town. Unfortunately their real business was making funny money so her job didn't last very long. William Christopher played the new doctor in town. He played golf and drove a convertible sports car. Look out!
That Peterson kid could not carve a turkey though. A patient on an operating table wouldn't have stood a chance!
