This marks Kate Micucci's first appearance as Ally Stark, making her the fourth actress to play the role. An inside joke has Doug wondering who she really is. Interestingly, just a few episodes earlier, in Check Mate (2010), Kate played the role of a waitress.
Duffy (Kathleen Rose Perkins) jokingly guesses that Eddie (Brad Garrett) is an Easter Island Head. Garrett voiced the Easter Island Head in the Night at the Museum trilogy.
