Dean Winchester: Driver picks the music. Shotgun shuts his cakehole.
Sam Winchester: Why'd you let me fall asleep?
Dean Winchester: Because I am an awesome brother. What did you dream about?
Sam Winchester: Lollipops and candycanes.
Dean Winchester: Come on man. I know Sam, ok? Better than anyone. He's got more of a conscience than I do. I mean the guy feels guilty searching the internet for porn.
Dean Winchester: We know a little about a lot of things; just enough to make us dangerous.
Sam Winchester: Dean, there's ten times as much lore about angels as there is about anything else we've ever hunted.
Dean Winchester: You know what, there's a ton of lore on unicorns too. In fact, I hear that they ride on silver moonbeams, and that they shoot rainbows out of their ass!
Sam Winchester: Wait, there's no such thing as unicorns?
Dean Winchester: Damn cops.
Sam Winchester: They were just doing their job.
Dean Winchester: No, they were doing our job, only they don't know it so they suck at it.
Sam Winchester: Bon Jovi?
Dean Winchester: Bon Jovi rocks... On occasion.
Dean Winchester: What's a P.A.?
Sam Winchester: I think it's kinda like a slave.
Dean: Well that means that every storefront in town has got a ghost satellite dish.
Sam; And this place is packed with people summoning spirits.
Dean: Most of these guys can't even call a taxi.
Sam: All it takes is one.
Dean: That's gonna be like looking for a needle in a stack of fake needles.
