This Shark Latched Onto A Man's Arm And Wouldn't Let Go!

We aren't sure how this happens, but it happened to a man swimming in the ocean. This guy was just swimming along when a shark came up to the man and latched onto his arm. The shark didn't tear the flesh or try to remove the guy's arm. The shark just stuck to the man's arm. What do you do at that point? Well, the man swam to shore where it seems like a ton of people were interested in the incident, and also multiple people had ideas and solutions that they seemed to be just making up on the the spot. Ever have a shark on your arm?!?!?
