This sea story is from Vince Leah, also of Winnipeg:
During the Second World War operations in the South Pacific, an alert Royal Navy destroyer scooped up a U.S. sailor who had fallen overboard from his cruiser. The grateful American captain sent over a huge tub of ice cream.
Later in the day, the U.S. captain signalled the destroyer: “Why are you steaming so close?”
The answer: “We’re waiting for another of your men to fall overboard.”
