In "One Flew Over the Cuckoo's Nest" by Ken Kesey, the protagonist understands the importance of humor as a coping mechanism in the face of life's hardships. By laughing at the painful aspects of existence, individuals can maintain their mental well-being and resist the overwhelming pressures of the world. This perspective suggests that humor serves as a vital tool for survival in challenging circumstances.

Kesey's work highlights the struggle between sanity and insanity, particularly how society can drive individuals to madness. The quote encapsulates the idea that without the relief that laughter brings, the weight of despair can become unbearable. It emphasizes the need for resilience and the power of laughter to uplift the spirit amidst adversity.
