To me, and to many, Steven Spielbergs Jaws is one of the greatest movies of all time. Ever one to impress with his references and shout outs, Cisco directly quotes Spielbergs classic with his I got no spit line. This is the same line that Matt Hooper says to Quint as hes about to take a dip in a shark cage. Nervous at the proposition of travelling between worlds, and called out on his Jaws reference by Harry Wells, it turns out that Cisco totally wasnt quoting Jaws and was just absolutely soiling his pants at the notion of travelling to an alternative world.
