This is the eighth of ten appearances Sammy Smith makes in the series, most of the time appearing as the malt shop waiter.
Patty jokes with Betsy that "there's no hard feelings about Fort Sumter." Fort Sumter is situated in the harbor of Charleston, South Carolina, and it is the bombardment of this fort by Confederate forces in April 1861 that is considered to be the event that catapulted the United States into civil war.
Throughout the three seasons this program originally aired, each episode was broadcast by ABC on Wednesday at 8 p.m. (ET). Following this time slot on the CBS network, a rival network for ABC, was the sitcom The Beverly Hillbillies (1962). Patty's parting words to Betsy and her parents, i.e. "Y'all come back. Hear?" with banjo accompaniment, is similar to the sign-off used in the CBS sitcom.
