Jon's grandmother Joan Favreau cameos as a field trip guide in a scene in Central Park Zoo. In another reference to Swingers (1996), Ricky (Vince Vaughn) asks Bobby (Jon Favreau) if he could pick up the "vibes" a girl was sending him.
The license plate of Jimmy's (Vincent Pastore's) limo reads "DBLDN11". This is a reference to a blackjack strategy articulated in Swingers (1996), that one should always double down on an 11.
