Mr Rabbit went to sea in a boat fashioned from lettuce. As the shark nibbled in, the rabbit nibbled out and the resultant hole was truly a joint effort. "Now Mr Rabbit" said the shark. "Surely you will add meat to my greens." "Oh good" said the rabbit. "At least I wont drown, I've always had a fearful dread of that." And so the shark had his meat with his greens and the rabbit did not drown- surely a happy outcome for both.
