House's patient, Marina, asks, "Is this heaven?" He replies, "No. This is New Jersey." This is near-identical to a line about Iowa from the film Field of Dreams (1989).
At the end of the episode, you see House's apartment number is 221. This is a reference to House being based on Sherlock Holmes, who lives on 221B Baker Street.
This episode won a 2008 Golden Reel Award for Best Sound Editing in Television: Short Form -- Dialogue and Automated Dialogue Replacement.
