Orr tittered triumphantly. "Because they're better than horse chestnuts... When I couldn't get crab apples," Orr continued, "I used horse chestnuts. Horse chestnuts are about the same size as crab apples and actually have a better shape, although the shape doesn't matter a bit."

"Why did you walk around with crab apples in your cheeks?" Yossarian asked again. "That's what I asked."

"Because they've got a better shape than horse chestnuts," Orr answered. "I just told you that."

"Why," swore Yossarian at him approvingly, "you evil-eyed, mechanically aptituded, disaffiliated son of a bitch, did you walk around with anything in your cheeks?"

"I didn't," Orr said, "walk around with anything in my cheeks. I walked around with crab applies in my cheeks. When I couldn't get crab apples I walked around with horse chestnuts. In my cheeks.”
