Dean: And I'm still me, okay? So, so, you might see things different now. Call it a runner's high or some crap. But that doesn't mean that something's going on with me, okay?
Sam: Yeah, okay.
Dean: No, don't say "yeah, okay," like "yeah, okay."
Sam: Yeah, okay.

Dean: It's kind of like Bewitched, you know. Don's Darren, doesn't even know it. Lots of laughs until you cheat on your wife.
Sam: Witch reference? Really?
Dean: Dude. Nicole Kidman was in the remake. Redhead. Hello.

Jenny Klein: There were tiny beating hearts in my cupcakes. There were hearts in my cupcakes. Hearts in my cupcakes. That's never happened before, hearts in my cupcakes!
Dean: Shall I slug her?
Sam: Give it a second.

Dean: Now she's just getting nasty. Killing the girlfriend is one thing, but his commemorative bust? That's got to hurt.

Dean: Okay, uh, obviously you two are capable of wiping each other out. Right? But you haven't, huh? Which means that you two... you still value whatever it is you got. And--and you want to keep that dance going. Maybe it's punishment, maybe it's sick, messed-up, erotic, kinky, clamps-and-feathers kind of love...
Sam: Okay, okay, that's--that's going way too deep there, cowboy.

Dean: Sam, I am so very, very, very, very, very, very tired.
Sam: Dean, like it or not, the stuff you don't talk about doesn't just go away. It build up. Like whatever's eating at you right now...
Dean: There's always something eating at me. That's who I am. Something happens, I feel responsible. All right, uh, the Lindbergh Baby--that's on me. Unemployment--my bad.

The amount and type of living and dead plant life changes around the bus bench between the side shot when Dean walks toward it, and the next shot when he's standing behind it. In the first shot there is far more plant life under and around the bench, and some of it is alive. In the second shot, there are only two plants and they're dead.
