Joker

From the film "The Dark Knight" (2008)

"Why so serious?"

This quote has become a symbol of the Joker in this movie.

"Introduce a little anarchy. Upset the established order, and everything becomes chaos. I’m an agent of chaos."

"Madness, as you know, is like gravity. All it takes is a little push."

"I believe whatever doesn’t kill you, simply makes you… stranger."

"Do you wanna know how I got these scars?"

From the film "Joker" (2019)

"I used to think that my life was a tragedy, but now I realize, it’s a comedy."

"The worst part of having a mental illness is people expect you to behave as if you don’t."

"Is it just me, or is it getting crazier out there?"

"I have nothing left to lose. Nothing can hurt me anymore."

From the comic "Batman: The Killing Joke" (1988)

"All it takes is one bad day to reduce the sanest man alive to lunacy. That’s how far the world is from where I am. Just one bad day."

"If I'm going to have a past, I prefer it to be multiple choice!"

From other sources

"Smile, because it confuses people. Smile, because it's easier than explaining what is killing you inside."

"As you know, madness is like gravity...all it takes is a little push."

"They laugh at me because I’m different. I laugh at them because they’re all the same."

The Joker is a character full of complexity and nuance, and his quotes often contain deep and paradoxical thoughts about life, society, and humanity.
