Men O'War

Two sailors on leave, Stanley and Oliver meet two girls at a park and invite them to have a soda. Unfortunately, the boys have only enough money to split theirs, a point which Oliver can't seem to get across to his friend. That problem is solved when Stanley hits the jackpot on a slot machine. Now with enough money to hire a boat, they start a battle-royal with other boaters, with everybody eventually winding up in the lake. (imdb)
