Dean: I mean, come on Sam. What are we doing?
Sam: Were hunting a ghost.
Dean: A ghost, exactly. Who does that?
Sam: Us.
Dean: Us, right. And that Sam is exactly why our lives suck. I mean come on, we hunt monsters. What the hell? Normal people, they see a monster and they run, not us. No, no, no we search out things that want to kill us, yeah, huh, or eat us. You know who does that? Crazy people. We are insane.
