The maps on the wall behind Andy's desk have now changed from a map of Nevada and an upside-down map of Idaho to North Carolina.
This is the first episode in which a large window and a space heater are next to the cell closest to the front door. There used to be a solid wall, with a door on the adjoining wall. There is also a lounge chair.
In season one, the opening credits are primarily verbal. Beginning in season two, the names of Andy Griffith and Don Knotts appear onscreen as well.
The layout of the Taylor's home changed in the second season when compared to the first season. The new general layout continued through most of the rest of the series.
