In The Tarot Cafe, there's the end of the story of a man who falls in love with a lake spirit. Their relationship seems doomed when he accidentally hits her three times, forcing her to return to living on the lake. He gets around the problem and allows them to have a life together by buying a boat for them both to live on. And he proposes to her with a doughnut, instead of a ring (which is doubly sweet seeing as the lake spirit loves food more than jewelry).
