Minor correction: The phrase refers to a scene in a three-part episode of the American television series Happy Days first broadcast on September 20, 1977. In the "Hollywood" episode, Fonzie — wearing swim trunks and his trademark leather jacket — jumps over a tank containing a shark while on water skis.
Fun game!
