Joe: What are you worried about? This job is going to last a long time.
Jerry: Well, suppose it doesn't?
Joe: Jerry, boy, why do you have to paint everything so black? Suppose you got hit by a truck. Suppose the stock market crashes. Suppose Mary Pickford divorces Douglas Fairbanks. Suppose the Dodgers leave Brooklyn!
