Sara: What tipped you to the ring?
Sara: Peter Benchley's Jaws?
Catherine: No, it was in Steven Spielberg's Jaws. They had this mechanical shark named Bruce. And he kept swimming round and round in circles.
Sara: How come?
Catherine: His dorsal fin was bent.
Sara: How did Bruce's fin get bent?
Catherine: Same way the kid's ring did. It hit something.
