Dean, Melanie and others in “Unfinished Business”

Dean

Yeah. See, there's, uh, fake whoo-whoo crap, and there's real whoo-whoo crap.

Well, yeah, but... ghosts?

Dean

Oh, trust me. There's a lot weirder out there than that.

So "The X-files" is real, or you just stopped talking like an FBI agent.

Sam

Well, um... we're not FBI agents.

I need a drink.

Dean

I support that.
