The opening scene has Fran buying white tulips to impress Maxwell's mother (Dina Merrill), who will be visiting. The scene parodies 'That Girl (1966)' in which every episode started with a small cold open and the dialogue would always turn to 'Ann Marie' (Marlo Thomas), as one of the characters would make an assertive reference to her as "that girl"; and the camera would freeze frame on a surprised 'Ann', just like the florist (Richard Julian) does to Fran.
The title is modeled after the excellent thriller-film noir, The Two Mrs. Carrolls (1947), starring the ultimate man's man and movie star par excellence, Humphrey Bogart.
Beautiful fresh flowers always graced the Sheffields' entryway. This is the first and only time a scene takes place at a florist's in the entire series. The flowers being bought here, and fought over by the "two Mrs. Sheffields", are white tulips.
During the late 1950s and 1960s, Dina Merrill (Elizabeth Sheffield) was believed to have been marketed as a replacement for Grace Kelly, and in 1959, she was proclaimed "Hollywood's new Grace Kelly".
