Trivia

 * There are numerous references to the movie Jaws in this episode. The Shark is called Bruce, the same name as the mechanical shark in Jaws. Cisco says “Just when you thought it was safe to go back to the suburbs” referencing the Jaws 2 tagline “Just when you thought it was safe to go back in the water.” They also say “We’re gonna need a bigger Flash” referencing the line “We’re gonna need a bigger boat” in the original Jaws. Cisco also says he should be “playing Quint” referencing a character in the original movie. Wells then points out that Quint dies in the film.
