This guy is smiling now, but that's only because he barely escaped becoming lunch for a hungry shark.

He and his friends are casually trolling through some shark infested waters when one of them has a brilliant idea.  "How funny would it be if we threw Johnny Chumbucket into the water?!"

Luckily everyone got a laugh out of it instead of a peg leg after the shark nearly missed him.

If my friends ever tried anything like this, I would find new friends . . . after I pooped in their wetsuits.
