In this show, Samantha teaches Uncle Arthur (played by Paul Lynde) how to drive a car. In Driving Is the Only Way to Fly (1965), Paul Lynde portrayed a driving instructor (Harold Harold) who was teaching Samantha how to drive.
In this episode you see the "Corner Church" across (diagonally) from the Stephens home. At the Columbia Ranch, where these exterior scenes were shot, the Kravitz house is not really across the street from the Stephens' home, but actually in between the church and the house used on I Dream of Jeannie (1965), on the same street (Blondie St).
The "woman with broom" portrait that usually hangs in the hallway is replaced for this episode by a mirror.
The last time there was a glass mirror adjacent to the front door was when Darrin (Dick York) was trapped in the mirror with sound effects of a lion pursuing him and his parents thought the mirror with him in it was some new technology.
