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?
