Don Knotts stayed awake for two days and nights and did not shave so that he could look tired for the scene in which Barney comes to work looking scraggly.
Based on the number of people that emerge from the jail cells, Barney made 19 arrests.
When Barney is reading the charges against the townspeople, there are two maps on the wall behind Andy's desk. The maps are upside-down maps of Idaho and Nevada.
As seen in this episode, the Mayberry Hotel serves breakfast between 8:00 and 9:30 AM, lunch between 12:30 and 2:00 PM and dinner at 7:00 PM.
This is the first of two episodes in the series to show a flashback. The other one is "Three Wishes for Opie."
