Did i ever tell you the definition of insanity?

Did I ever tell you what the definition of insanity is? Insanity is doing the exact same ... thing over and over again, expecting... ... to change. That is crazy; but the first time somebody told me that...I dunno, I thought they were ... 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 ... pricks, everywhere I looked, doing the exact same ... 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 ... problem in your head? Do you think I am ... you? Do you think I am lying? ... you! Okay? ... 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 ... crazy. It's okay... It's like water under the bridge . . . Did I ever tell you the definition... of insanity?
