"After he made up his mind to spend the rest of the war in the hospital, Yossarian wrote letters to everyone he knew saying that he was in the hospital but never mentioning why. One day he had a better idea. To everyone he knew he wrote that he was going on a very dangerous mission. "They asked for volunteers. It's very dangerous, but someone has to do it. I'll write you the instant I get back." And he had not written anyone since."
