When Nandor is leaving to become "human" again he says a quote from the TV show Frasier, "Good night Seattle and good mental health." Frasier is one of Kayvan Novak's favorite shows.
The lyrics for the opening theme are sung in Nandor's native tongue, Farsi.
The episode won an Emmy Award for Outstanding Fantasy/Sci-Fi Costumes.
As Colin Robinson enters the room belly-dancing, he is singing an adapted version of "Happy Birthday, Mr. President", a song famously sung by actress and singer Marilyn Monroe for President John F. Kennedy at a celebration of his 45th birthday.
In the car with Guillermo, Nandor raps a few lines from One Week by Barenaked Ladies. This may be a reference to S03E04 Casino when he is obsessively playing The Big Bang Theory game in the casino, for which Barenaked Ladies wrote the theme song.
