Australian man jumps on tiger shark for a dare

A video has been posted to YouTube of an Australian man leaping on top of a passing shark from the side of a boat after being dared to do it by a friend.

In the footage, one of the men on the boat can be heard saying "Catch this tiger shark, Brett," and then "You gonna jump on it? I dare you. It's only a little tiger".

To which Brett replies: "It's only a man-eater".
