Sam: What kind of something?
Dean: (Castiel) said that he couldn't talk about it over the phone.
Dean: Because he's a weird guy, okay? He's a weird, dorky, little guy.
Castiel: Thank you for coming.
Sam: Spears and Aguilera?
Castiel: I've noticed your aliases are usually the names of popular musicians.
Metatron: Just a second. (Gadreel comes in a second later)
Gadreel: I gave you a second.
Metatron: You are such an... angel sometimes.
Meta: And still--still, they're choosing him over me. I mean, sure, he's cute. And Castiel has this... simple charm. he's like a mentally deficient puppy. But I'm lovable. And funny. I made God laugh--twice!
Hannah: Sir, this morning Josiah wasn't at roll call.
Sam: Uh, roll call? You hold, uh, roll call?
Castiel: They like to hear me say their names.
Dean: I know a couple of women like that.
Metatron: So, wait. You're turning me down because of... bowling?
Tyrus: And I like being an independent operator. And I hear you're losing. And I hate your face.
Tessa: So, you're here. Why? You just love musical theater?
Dean: Only if it's Fiddler.
Castiel: It's Enochian. I believe it's some sort of riddle. "Why is six afraid of seven?" Now, I assume it's because seven is a prime number, and prime numbers can be intimidating.
Metatron: Castiel, bet you're not happy to see me.
Dean: Is anyone ever?
Metatron: Dean, always with the B-grade '80s-action-movie wit.
Music: Cheek to Cheek (Frank Sinatra)

Tolkein (and three movies based on it) concerning the adventures of a group comprised of humans, elves, and hobbits to destroy an evil ring. To destroy the ring, it must be cast into Mount Doom.
