No worries

On a WW2 battleship one guy was all worries and another tried to get him to lose em, but the fella kept saying they'd not make it through that night. Before the conversation was over they had a bet on it for a thousand dollars. He didn't seem to realize it was a bet he couldn't win, and that the other one couldn't lose. They made it through the battle, and the night, and the one who'd been doing all the worrying, was also out a thou ; )
