Dean: Okay, a wall. Sounds good.
Tessa: But it's not permanent.
Death: She's right. Nothing lasts forever. Well, I do.

Dean: What's the bet?
Death: Don't roll your eyes, Dean. It's impolite. Now when you fetch my ring, put it on.
Dean: What?
Death: I want you to be me for one day.
Dean: Are you serious?
Death: No, I'm being incredibly sarcastic.

Tessa: Wow. They'll just let any slack-jawed haircut be Death these days.
Dean: Well, you're all charm today, aren't you?

Balthazar: Well, here's one for the list of dumbest things ever. Summon the angel who wants to kill you.
Sam: Desperate times. I need your help, Balthazar.
Balthazar: Interesting. Since last time we met, you wanted to, what was it? Oh yes, yes. "Fry my wings, extra crispy."
Sam: Well, that was a misunderstanding.
Balthazar: Some misunderstanding.

Tessa: Just so you know, when people die, they might have questions for you. Well, not you, but Death.
Dean: You mean, like "How did Betty White outlast me"?

Heart Attack Victim: Why?
Dean: You think maybe it was the extra cheese?
Heart Attack Victim: Yeah. It was good, though.
Dean: That a local place?
Tessa: Dean...
Dean: Right. Umm, time to go, man. Sorry.
Heart Attack Victim: Wait. Will you tell me what it all... means?
Dean: Everything is dust in the wind.
Heart Attack Victim: That's it? A Kansas song?
Tessa: Sorry. He's new.

Tessa: Dean, you have to take her.
Dean: Says who?
Tessa: Death.
Dean: I'm Death.
Tessa: You know what I mean.
Dean: Well who tells him?
Tessa: I don't know. It just is. It's destiny.
Dean: Give me a break. I spent my whole life fighting that crap. There's no such thing as destiny. Just like there was no Apocalypse. Just a bunch of stuck up mooks who didn't want us human slaves asking questions.

Bobby Singer: I may have been born at night, boy, but I wasn't born last night.

Bobby Singer: Ain't nobody killing me in my house but me.

Dean: Well what's with you and cheap food?
Death: I could ask you the same thing.

Death: This is hard for you, Dean. You throw away your life because you've come to assume that it'll bounce right back into your lap. The human soul is not a rubber ball. It's vulnerable, impermanent, but stronger than you know... and more valuable than you can imagine.

The episode takes its title from a very old story. A servant sent to the Baghdad market, is jostled by a passerby and turns to see that it is Death. Death gestures threateningly and the terrified servant races back to his master and there borrows a horse. He flees to the town of Samarra, certain Death will not find him. The master visits the market and finds Death, asking why he threatened the servant. Death replies that there was no threat, but merely surprise: he was startled to see the servant in Baghdad because he had an appointment with him that evening in Samarra...

Bobby Singer: Don't say "Here's Johnny."

In the 1980 movie The Shining, Jack Nicholson's character Jack Torrance breaks down a door with an axe, while mimicking the opening to The Tonight Show Starring Johnny Carson, where Ed McMahon would typically say the same thing.
