Andy still wears the cast on the wrist he injured bringing in the Gordon boys in the previous episode. The real-life reason for the cast has been debated for years, but it is believed that, in reality, Griffith sprained his wrist when he got angry on the set and put his hand through a wall.
Rafe Hollister's farm is the same one used as the Flint farm in season one's "Ellie Saves a Female."
This episode is one of the rare times that Barney teases Andy, over his liking Mary, instead of the more frequent teasing of Barney by Andy.
This is the second time that Griffith will bear down on 'Rafe Hollister' (Jack Prince) while he's firing a rifle at Andy. The first time is (as 'Luke Rainer') in "The Inspector." He also fires at Andy and Barney (as 'Ben Sewell') in "Alcohol and Old Lace."
This is the first of two appearances of Mary Simpson, the County Nurse. The second will come three episodes later, in "Three's a Crowd," with Sue Ane Langdon replacing Julie Adams in the role.
