At the end of the episode The Spice Girls sing "Spice Up Your Life". "Spice Up Your Life" is from their second album "Spice World" and their 1997 movie "Spice World".
While this episode has the Spice Girls as guest stars, it also happened to air on the 21st birthday of former member Michelle Stephenson, who is known as the 'Sixth Spice Girl' or the 'Pete Best' of the Spice Girls group.
Aired just 20 days before the Spice Girls' film, "Spice World" premiered in the U.S.
