A passage found in Archbishop Fulton Sheen's autobiography:
One day on a New York subway when the door opened at Forty-second Street a drunk got in and threw himself alongside of me and began reading a paper which I doubted very much he could see in his condition. Then he said to me: "How does a man get diabetes?" I said: "Oh, by getting drunk and paying no attention to his wife and children." A moment later I was sorry for having made that quick diagnosis. I asked him: "Why did you want to know how a man got diabetes?" He said: "I was just reading that the Pope had diabetes."
