Orr has a bucktoothed smile and frequently puts crabapples or horse chestnuts in his cheeks and rubber balls in his hands. He constantly teases Yossarian asking him if he wants to know why, to which Yossarian invariably says "yes". Orr never gives any straightforward explanation for this other than he wants big cheeks and to detract from the peculiarity of this he keeps rubber balls in his hands. As he explains the latter, "Every time someone asked me why I was walking around with crab apples in my cheeks, I'd just open my hands and show them it was rubber balls I was walking around with, not crab apples, and that they were in my hands, not my cheeks. It was a good story. But I never knew if it got across or not, since it's pretty tough to make people understand you when you're talking to them with two crab apples in your cheeks."
