Quote from : One Flew Over the Cuckoo's Nest Movie

Dr. Spivey: Well, the real reason that you've been sent over here is because they wanted you to be evaluated... to determine whether or not you are mentally ill. This is the real reason. Why do you think they might think that?
McMurphy: Well, as near as I can figure out, it's 'cause I, uh, fight and fuck too much.
