“Clevinger really thought he was right, but Yossarian had proof, because strangers he didn't know shot at him with cannons every time he flew up into the air to drop bombs on them, and it wasn't funny at all”

“Who's they?" He wanted to know. "Who, specifically, do you think is trying to murder you?""Every one of them," Yossarian told him."Every one of whom?""Every one of whom do you think?""I haven't any idea.""Then how do you know they aren't?""Because..." Clevinger sputtered, and turned speechless with frustration. Clevinger really thought he was right, but Yossarian had proof, because strangers he didn't know shot at him with cannons every time he flew up into the air to drop bombs on them, and it wasn't funny at all.”

“But Yossarian knew he was right, because, as he explained to Clevinger, to the best of his knowledge he had never been wrong.”

“...'You haven't got a chance kid,' he had told him glumly. 'They hate Jews.' 'But I'm not Jewish,' answered Clevinger. 'It will make no difference,' Yossarian promised, and Yossarian was right. 'They're after everybody.”

“The dead man in Yossarian's tent was a pest, and Yossarian didn't like him, even though he had never seen him. Having him laying around all day annoyed Yossarian so much that he had gone to the orderly room several times to complain to Sergeant Towser, who refused to admit that the dead man even existed, which, of course, he no longer did.”

“Oh, they're there all right," Orr had assured him about the flies in Appleby's eyes after Yossarian's fist fight in the officers' club, "although he probably doesn't even know it. That's why he can't see things as they really are." "How come he doesn't know it?" inquired Yossarian. "Because he's got flies in his eyes," Orr explained with exaggerated patience. "How can he see he's got flies in his eyes if he's got flies in his eyes?”

“Orr would be crazy to fly more missions and sane if he didn't,but if he was sane he had to fly them. If he flew them he was crazy and didn't have to; but if he didn't want to he was sane and had to. That's some catch, that catch-22.”
