When Jeff and Francine are smoking in the living room, her bangs are standing straight up. This is a nod to the film There's Something About Mary (1998), when she uses semen she believed was hair gel.
In one of the court room scenes we see a woman wearing a "lady bugs" badge pin from season one episode 16 "Not particularly desperate housewives".
The title is a reference to the movie The People vs. Larry Flynt.
