From The Joys of Yiddish, by Leo Rosten
The famous Duvner _maggid_, a _gaon_, was asked by an admiring student: “How is it that you always have the perfect parable for the topic under discussion?” The _gaon_ smiled. “I'll answer with a parable.” And he told the following story: A lieutenant of the Tsar's cavalry, riding through a small _shtetl_, drew his horse up in astonishment, for on the side of a barn he saw a hundred chalked circles---and in the center of each was a bullet hole! The lieutenant excitedly stopped the first passerby, crying, “Who is the astonishing marksman in this place? Look at all those bull's-eyes!” The passerby sighed. “That's Shepsel, the shoemaker's son, who is a little peculiar.” “I don't care what he is,” said the lieutenant. “Any man who can shoot that well---” “Ah,” the pedestrian said, “you don't understand. You see, first Shepsel shoots---_then_ he draws the circle.” The _gaon_ smiled. “That's the way it is with me. I don't search for a parable to fit the subject. I introduce the subject for which I have a perfect parable.” -- _The Joys of Yiddish_, p. 126
