In the denouement, Fran is wearing a Bob Mackie dress, which was previously worn by Sharon Stone in Casino (1995).
In this episode is a memorable scene where Fran and CC go to a sushi restaurant. Fran mistakens wasabi for mustard and eats a heap of it. After dropping (passing out) on the floor she gets up and remarks -- in a rare, non-nasal voice for her character -- how the wasabi really clears her sinuses.
