Jessica St. Clair, who guests as Kay's sister is a frequent collaborator and co-writer of Lennon Pelham's.
According to Kay (Lennon Parham) and Constance (Pam Grier), half the male population of Bucksnort, Nebraska lost their virginity on a hay bale. The other half in the bed (the back part) of a pickup truck.
Whatever a "Grisham Gals Special" is (alluding to a sexual act), it is illegal in seven states, but not in Nebraska.
Rio ( Lake Bell) and Kay ( Lennon Parham) are in a pickup truck singing along to Carrie Underwood's song "Before He Cheats", a song about a woman taking revenge on her potentially unfaithful husband/boyfriend, while headed to see Mike (Dax Shepard).
