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: 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.
