Sam Winchester: Looks like this guy had a history with dogs.
Dean Winchester: Meaning?
Sam Winchester: Five years ago, he was arrested for running a dog-fighting operation.
Dean Winchester: Classy. All right. So, what? He causes so much misery that some rottweiller goes 'Cujo' on him from the grave? Wait a sec. Do... dogs even have ghost?
Sam Winchester: First I've heard of it.
Dean Winchester: That sounds weird. 'Ghost Dog'?
Sam Winchester: No weirder than 'Ghost Car,' you know?
Dean Winchester: You know that does sound right, vengeance on the guy that Michael Vick'd you.
Dean Winchester: [Giving himself a pep talk while waiting for a waitress with whom he's arranged a rendezvous] It's been awhile. Control yourself. It's nothing but a ground ball. You just gotta... put your mitt down. You are Dean Winchester. This is what you do.
