When Goober drives up to the gas station after returning from vacation, the same cars are at the gas pumps in the same order that they were when Andy and Floyd drove up to the station earlier in the episode.
The first mention of a Drive-in movie theater in Mayberry when Goober mentions going there to Flora.
In this episode Burt Mustin is never called by name and is credited as Old Geezer, even though Mustin had played a character named Jud Fletcher for six years on the series.
As Andy and Floyd pull up to the gas station, Floyd can be seen wearing a dark sports coat. But a close up shot inside the car shows him wearing a light colored jacket; possibly his Barber's smock.
Goober visits Flora at her house twice. Throughout the series the audience has no idea where or how Goober lives. A guess can be made from the fact that his cousin Gomer lived in a "kitchenette" at the back of the filling station, referenced in "Gomer the House Guest," and "Barney and Thelma Lou, Phfftt." ********* UPDATE ********* In Season 2, Episode 14 of Mayberry R.F.D., "Goober's Niece," Goober's home is revealed. Goober lives in a boarding house and has a landlady.
