Ken Berry and Leticia Roman appeared together in the F Troop episode La Dolce Courage. Here again she played the daughter of an Italian father who was played by Jay Novello.
The last episode of the series.
This is the only appearance of Mario's family. They will not be with Sam at the beginning of his series "Mayberry, R .F.D." The assumption is that they may have joined one of the Italian farms near Siler City after all, or bought one of their own.
The TV and TV cart in Sam Jones' house is the same one that is in Mary Alice Carter's house in season 8, episode 1 "Opie's First Love."
A sign at the train depot reads "MAYBERRY pop. 5360 Elev. 671." In the series Mayberry is said to be around 2000 people according to John Masters. Howard Sprague said Mayberry was around 1800 people. Perhaps the town of Mayberry has around 2000 and the County of Mayberry has 5360. Typically a train station would have only listed the town population.
