First appearance of the Sam Jones (Ken Berry) character who went on to star in Mayberry R.F.D. (1968).
Error: Sam Jones wouldn't be eligible for Town (City) Council. His farm is outside of the town limits and to qualify for town council, a person would have to live within the town limits.
Howard describes himself, Goober, Andy, and Emmett as a "moving force" in their town government. As two of them worked for the county, and two of them were merchants, in a town Mayberry's size he's not altogether wrong.
Jack Dodson's voice can be heard in the background when Gober requested a Stop sign as he leaves and Howard (Jack Dodson) arrives. Howard can be heard saying 'your encouragement, helped a lot' twice as background noise.
