why so serious

The phrase "Why so serious?" is famously associated with the character The Joker from the 2008 film The Dark Knight , directed by Christopher Nolan. It’s a line The Joker uses to mock others and challenge their seriousness or rigidity, often before causing chaos or mayhem. The phrase has since become iconic, symbolizing a provocative challenge to take life less seriously or to confront the darker, unpredictable aspects of reality with a twisted sense of humor.
