In media
Port Monmouth was featured in a 1990 episode of Saturday Night Live during a Weekend Update sketch featuring Al Franken covering a cocaine deal in Port Monmouth, NJ. The tugboats Ocean Prince and Newport can be seen in the footage suggesting it was actually filmed locally in New York City for the show as Port Monmouth and neighboring Belford Harbor are home to fishing vessels - which is noted by Al during the sketch. At the time of filming those tugboats were under the Amerada Hess Corporation which had a storage facility and pier in Red Hook, Brooklyn.
