At the beginning, Penelope and Spencer are at a sci-fi convention dressed as the 11th Doctor and 4th Doctor, respectively, from Doctor Who (2005) and Doctor Who (1963). When they run into Kevin and his female friend, they are also dressed as characters from Doctor Who. Kevin is cosplaying as 11th Doctor (like Penelope) and the girl is Amelia Pond.
When the heist begins, a German tourist whispers to his wife: "Wir müssen heraus bevor Sie uns erschießt," which translates to: "We must get out of here before she shoots us!" Izzy replies in German with: "Versuch es nicht, sonst ich streiche den Wand mit dem Blut deiner Frau," which is: "Don't try this, otherwise I have to paint the wall with the blood of your wife!"
The main antagonist group of this episode, the Face Card Gang, may be a nod to the DC's Royal Flush Gang, a group of playing card-themed super-villains. Their code names are based on an ace-high straight in poker: King, Queen, Jack, Ten and Ace.
The spin kick JJ uses to take down Izzy is shown in season 8's title sequence as a transition.
