Book excerpt: The Fun of Getting Thin: How to Be Happy by Samuel G. Blythe is about the art of dieting. Excerpt: "A fat man is a joke, and a fat woman is two jokes—one on herself and the other on her husband. Half the comedy in the world is predicated on the paunch. At that, the human race is divided into but two classes—fat people who are trying to get thin and thin people who are trying to get fat. Fat, the doctors say, is fatal. I move to amend by striking out the last two letters of the indictment. Fat is fat."
