"You can easily tell when someone has been hit by a spear. he turns a deep shade of bitter. David never got hit. Gradually, he learned a very well-kept secret... One, never learn anything about the fashionable, easily mastered art of spear throwing. Two, stay out of the company of all spear throwers. And three, keep your mouth tightly closed. In this way, spears will never touch you, even when they pierce your heart."
