The establishing shot used just before Sabrina and Valerie first get turned away at the 18+ club is the very same shot recycled from an earlier episode when Sabrina and her friends/aunts are waiting to meet The Violent Femmes in season 1.
This episode features pirates 4years before the 2003 Pirates of the Caribbean craze. Isaac C. Singleton Jr. plays the bouncer to the club and Bo'Sun from the first pirates movie.
