Agreed - saw this happen on a boat. People were diving from the boat into the sea. One fairly large guy who couldn't swim decided it looked like fun and followed suit.

At first no one realised how bad the situation was, with the next person jumping soon after. Within 20-30 seconds someone asked "hey, is he drowning?" and 4 guys (not trained as lifeguards) swam over and struggled to keep him afloat, even with a dozen foam float "sticks", he almost took them all down with him. He was quiet, there wasn't much splashing, he was trying to keep afloat with his arms and wasn't kicking with his legs at all.

It was scary and in retrospect hilarious; the guy has since gained a legendary status in the office although it could have turned out very differently - possible nomination for a Darwin award.
