"The countless tight squeezes you have been in during the course of your life, the desperate moments when you have felt an urgent, overpowering need to empty your bladder and no toilet is at hand, the times when you have found yourself stuck in traffic, for example, or sitting on a subway stalled between stations, and the pure agony of forcing yourself to hold it in. This is the universal dilemma that no one ever talks about, but everyone has been there at one time or another, everyone has lived through it, and while there is no example of human suffering more comical that that of the bursting bladder, you tend not to laugh about these incidents until after you have managed to relieve yourself--for what person over the age of three would want to wet his pants in public? That is why you will never forget these words, which were the last words spoken to one of your friends by his dying father: "Just remember, Charlie," he said, "never pass up an opportunity to piss." And so the wisdom of the ages is handed down from one generation to the next."
