What do you say to a bunch of Californian kayakers getting circled menacingly by a hammerhead shark?

Nothing. Because you've already fled the scene on your jet-ski.

This incident occurred in La Jolla California, and resulted in beach closures. Fair play to the kayakers, they stay remarkably calm about it. Maybe it's because seconds before they started recording, they'd thrown there kayaking-mate Graham into the water to appease the hungry sharks below (there is no evidence to support this theory).
