We've all seen or heard of a car or motorcycle doing a doughnut. You know, when a driver maneuvers his vehicle, creating a circular skid mark. Well, two fisherman in Florida hit a rough wave and were thrown from their boat in shark-infested waters. After that, the boat began to create doughnuts in the water for over an hour. I mean, really dude, that's some nice circle work that probably kept the sharks away.
