"You fellas are crazy. I didn't even touch him."

This is the first appearance of a word that will reappear many times in this book. Who or what is crazy, and on what grounds, is a constant point of contention between the characters (almost everyone will accuse almost everyone else of being crazy at one point or another) as well as an issue in the book as a whole.

Though most of the men of the 256th Squadron will accuse the others of being crazy, and defend themselves against the charge of being crazy, Yossarian will repeatedly try to get himself declared crazy. He will act crazy, too, in the hope of getting out of having to fly more bombing missions.
