One Flew Over the Cuckoo's Nest

One Flew Over the Cuckoo's Nest is a novel written by Ken Kesey. Set in an Oregon psychiatric hospital, the narrative serves as a study of institutional processes and the human mind as well as a critique of behaviorism and a tribute to individualistic principles. It was adapted into the Broadway play One Flew Over the Cuckoo's Nest by Dale Wasserman in 1963. Bo Goldman adapted the novel into a 1975 film directed by Miloš Forman, which won five Academy Awards.

Context: While McMurphy laughs. Rocking farther and farther backward against the cabin top, spreading his laugh out across the water — laughing at the girl, at the guys, at George, at me sucking my bleeding thumb, at the captain back at the pier... and the Big Nurse and all of it. Because he knows you have to laugh at the things that hurt you just to keep yourself in balance, just to keep the world from running you plumb crazy. He knows there's a painful side; he knows my thumb smarts and his girlfriend has a bruised breast and the doctor is losing his glasses, but he won't let the pain blot out the humor no more'n he'll let the humor blot out the pain.
