Mayor Stoner's house is the same structure that was used for Aunt Pitty Pat's house in Gone with the Wind (1939).
Mayor Stoner reveals here that his wife's name is Mabel. Floyd also reveals his wife's name is Mabel in the episode Quite Sam. ***** UPDATE ***** This information is INCORRECT. Floyd's wife's name in "Quiet Sam" wasn't 'Mabel.' Her name was 'Melba.'
The plot of this episode revolves around Aunt Bee's (Frances Bavier) birthday. Frances Bavier was sixty-years-old (born December 14, 1902) when this episode aired.
The name of the beauty shop that Clara and Bee come out of is "Wakefield." Along with the Carters they were one of the two feuding families in the county. Throughout the series many of the same family names were sprinkled into the scripts, giving a sense of community to the series story arc. Among them are: Beasely, Gilley, Pyle, Walker, Crowley, Mendelbright, and more.
