If you were sitting inside of a boat fishing and a gigantic shark started circling you, what would you do? Laugh? Nah, right? Of course not. But that's exactly what a group of fisherman did recently off the coast of Australia—and they almost paid the price for it.

The men, who were interviewed in the video above, laughed at the shark, fed it, and even tried to pet it as it circled their boat. But they stopped laughing when the shark tried to bite off their motor. They were finally able to shoo it away. But after leaving their boat, the shark swam over to another vessel that was nearby and tried doing the same thing to that boat as well. Fortunately, no one got hurt and both boats were OK. But the fisherman could have been in some serious trouble if the shark had done any more damage than it did.
