In Ken Kesey's "One Flew Over the Cuckoo's Nest," the notion of strength is intricately tied to the ability to find humor in difficult situations. The quote highlights a character's realization that true resilience often involves confronting adversity with a lighter perspective. Laughter serves as a means of coping and healing, suggesting that those who are able to joke about their struggles possess a deeper strength.

This idea emphasizes the importance of perspective in challenging environments, such as the mental institution depicted in the novel. While the characters may not initially find humor in their predicaments, the ability to eventually see the funnier side is portrayed as a sign of emotional growth and strength, showcasing how humor can be a vital part of overcoming hardships.
