|Each of The Andy Griffth Show episodes originally clocked in at 24 1/2 minutes. In syndication, the show was shortened to 22 minutes to allow for more commercial ads. The remaining 2 1/2 missing minutes is cut from the middle or the end of each show.|

|Mayberry's "Magic Doors"|
Doors on The Andy Griffith Show come and go. Three are notable:
The closet door in the living room. This door is just to the right of the front door. It "magically" comes and goes during early season episodes.
The back door in the kitchen. For the first five seasons, this door is on the sink wall. In the sixth season, the door "magically" moves to the dish cabinet wall and stays there through the remainder of the series' run.
The door near the front cell in the jail. This door is to the right of the front door in the courthouse and is believed to be the door to the restroom. The door "magically" disappears at the beginning of the second season to be replaced by a gas heater.
Other doors worth mentioning:
There is no door to the TV repair shop next to Floyd's barbershop.
The Taylor house apparently has a cellar but there's no door on the main floor leading to it.
The French doors next to the Taylor fireplace "magically" become a window during the series' run.
|Griffith had said early on that he only planned to do the show for five years. As that time approached, Knotts signed a movie contract to pursue a career in feature films. When Griffith reconsidered his earlier decision, Knotts tried to get out of or rework his contract. However, his film studio would not consider either option, so he was forced to leave the show.|
