This goof ball is in hot water. He decided to strip down and dive in the shark tank at an aquarium in Toronto. Reports say neither the man or the fish were injured, but I feel bad for the people who had to see him nude. Even though they look mean, sand tiger sharks are said to be relatively docile. I'm not sure if I would want to swim naked in a tank with any fish, they might mistake a certain body part for a worm and want to take a bite.
