At one point Hiro and Ando ride down an escalator in matching gray suits while in Las Vegas. It seems like an ode to the movie Rain Man because the characters in the film take a trip to Vegas and "cheat" at cards. They too ride down an escalator in matching gray suits.
The casino Hiro and Ando cheat at is the Montecito, the casino that Las Vegas (2003), another NBC show, is based on.
The original title for this episode was "Come Together".
