You sir, require some form of psychiatric help.

Did I ever tell you what the definition of insanity is?

Insanity is doing the exact... same fucking thing... over and over again, expecting... shit to change.

That... is crazy; but the first time somebody told me that...I dunno, I thought they were bullshitting me, so boom - I shot him. The thing is, okay... He was right.
And then I started seeing: everywhere I looked, everywhere I looked, all these fucking pricks, everywhere I looked, doing the exact same fucking thing... over and over and over and over again thinking: "This time, it's gonna be different; no, no, no, no, no, please... This time it's gonna be different."

...I am sorry, I don't like the way you are looking at me... Okay, do you have a fucking problem in your head? Do you think I am bullshitting you? Do you think I am lying? Fuck you! Okay? FUCK. YOU!
It's okay, man. I'm gonna chill, hermano. I'm gonna chill... The thing is... alright, the thing is: I killed you once already... and it's not like I am fucking crazy. It's okay... It's like water under the bridge.

Did I ever tell you the definition... of insanity?
