"[to Billy] You're just a young kid. What are you doin' here? You oughta be out in a convertible, why – bird-doggin' chicks and bangin' beaver! What are ya doin' here, for Christ's sake? What's funny about that? Jesus, I mean, you guys do nothin' but complain about how you can't stand it in this place here and then you haven't got the guts just to walk out!"

"You wanna bet? One week. I bet in one week, I can put a bug so far up her ass she won't know whether to shit or wind her wristwatch."

"But Doc, she was fifteen years old, going on thirty-five, Doc, and, uh, she told me she was eighteen and she was, uh, very willing, you know what I mean...I practically had to take to sewin' my pants shut. But, uh between you and me, uh, she might have been fifteen, but when you get that little red beaver right up there in front of ya, I don't think it's crazy at all now and I don't think you do either...No man alive could resist that, and that's why I got into jail to begin with. And now they're telling me I'm crazy over here because I don't sit there like a goddamn vegetable. Don't make a bit of sense to me. If that's what's bein' crazy is, then I'm senseless, out of it, gone-down-the-road, wacko. But no more, no less, that's it."

"I'm here to cooperate with ya a hundred percent. A hundred percent. I'll be just right down the line with ya, you watch. 'Cause I think we ought to get to the bottom of R. P. McMurphy."

Because all you do is fucking prance around school talking about your fucking faggoty, fairy fathers. I'll tell you what! I don't want to hear about your fucking fathers and how their assholes work, all right?! It makes me sick! And I... I fucking hope they fucking die of fag disease! Yeah, and speaking of dead fathers..., I just remember why bonehead, white trashed fucking donkey dick Marty, got so fucking freaked when I started talking about his daddy. His neanderthal, drunk dad, put a gun in his mouth and splattered his brains all over the wall. You know... I almost forgot that my mom told me that. She said he splattered his brains all over the wall. I thought it was sad at first, but now... I like it. His daddy splattered his brains all over the wall."
