Trivia: The Supernatural episode that they are filming in the alternate universe is titled "Echo."
Kevin Parks: Gets us right up to where they... just before they hit the window.
Robert Singer: You know, the part where they hit the window was the good part.
Kevin Parks: Well, we can clean up, reset the window, takes about 95 minutes, basically, so we'd have to blow off the scene where they sit on the Impala and talk about their feelings.
Robert Singer: Ha, right! You answer the hate mail.
Dean: Oh, crap. I'm a painted whore.
Dean: They put freakin' makeup on us. Those bastards.
Sam: For whatever reason, our life is a TV show.
Sam: I don't know.
Dean: No, seriously, why? Why would anybody want to watch our lives?
Sam: Well, I mean, according to the interview, not very many people do.
Sam: I'm just saying, we landed in some dimension where you're... Jensen Ackles and I'm something called a Jared Padalecki.
Dean: So, what now, you're Polish?
Dean: Dear Castiel, who art maybe running his ass away from Heaven, we pray that you have your ears on. Breaker... breaker.
Dean: Misha? Jensen? What's up with the names around here?
Misha: You guys! You really punked me! I'm totally going to tweet this one. "Hola, Misha-migos. J-Squared got me good. Really starting to feel like one of the guys."
Sam: (seeing his counterpart's tanning bed) What am I, Dracula?
Dean: George Hamilton Dracula.
Clif: We're not doing anything illegal, are we?
Sam: Would it make you feel better if we said no?
Misha: (seeing Sam's package) Priority. What's in it?
Sam: I bought part of a dead person.
Misha: Oh, cool.
Sam: (reading the episode script) Who wrote this? No one says "penultimate."
Dean: Gun. Mouth. Now.
Dean: Maybe we can't get out of, you know, Earth Number Two right now. But the least we can get do is get the hell out of the Canadian part of it. I hear one more conversation about hockey, I'm going to puke.
Sera: I'm trying to understand, Bob.
Robert Singer: Well, uh, Sera, we don't really understand it ourselves. But it appears that Jared and Jensen were seen beating an extra to death.
Jim Michaels: This is Jim here, Sera, and it wasn't all the way to death. Only partway, so that's a plus.
Kevin Parks: He could definitely still run.
Sam: So the character in the show, Bobby Singer...
Dean: What kind of a douche-bag names a character after himself?
Sam: Oh, that's not right.
Robert Singer: Guys, you can't come to work on poppers, and smuggle kidneys in from Mexico. And make up your own lines as you go. You cannot make up your own lines!
Dean: You heard my brother. That's right, I said brother. 'Cause you know what, Bob? We're not actors. We're hunters. We're the Winchesters. Always have been and always will be. And where we're from, people don't know who we are. But you know what? We matter to that world. In fact, we even saved the son of a bitch once or twice. And yeah, okay, here, maybe there's some fans who give a crap about this nonsense...
Robert Singer: I wouldn't call it nonsense.
Dean: But... Bob Singer--if that even is your name--tell me this. What's it all mean?
Robert Singer: Okay, this is good. I can work with this. I mean, we've all had our psychotic breaks, right? I can work with this.
Virgil: How do you do it? Live in this bloody shallow desert. Nothing greater than yourselves? Nothing but dirt when you die. No power, no magic.
Misha: I'm not following you at all.
Virgil: There's no magic in the universe.
Misha: I'm sorry! Please...
Virgil: Nothing but a bag of strings and pulleys.
Virgil: You should thank me for what I'm about to do.
Eric Kripke: Bob, dude, what the hell, right?
Robert Singer: Eric, thanks for coming.
Eric Kripke: Of course.
Robert Singer: I know you're busy. It means a lot that we can still, you know, call on you.
Eric Kripke: I know. Misha, right?
Robert Singer: Oh, I know, I know. it's just awful.
Eric Kripke: Totally. Totally awful, yeah. Hey, it got us the front page of Variety, though, did you see that?
Robert Singer: Front page. Really?
Eric Kripke: Yeah.
Robert Singer: But tragic.
Eric Kripke: Yeah, tragic, that's what I was going to say.

Exactly one minute after the show's Misha sent the tweet: "Hola, Misha-migos. J-Squared got me good. Really starting to feel like one of the guys," the real Misha sent the tweet to his followers.

Balthazar: You've seen The Godfather, right?

The movie spawned two sequels, in 1974 and 1990, and appears on numerous "Best Movie" lists.
Dean: Like... Bizarro-Earth?
Referencing DC Comics and Bizarro, an imperfect white-stone-faced duplicate of Superman who thinks the opposite of normal humans. Good is evil, happy is sad, and so on. Bizarro eventually creates or comes from a cube-shaped Bizarro-Earth populated with Bizarro clones, who manage to function despite their civilization functions the opposite of Earth society.
Dean: And... there's no place like home.
Referencing the popular 1939 movie, The Wizard of Oz. In the movie, Judy Garland, who plays Dorothy, is famous for repeatedly delivering the line "There's no place like home." The line is also the theme of the movie, that the best place to be at the end of the day is at home.
Dean: No hell below us, above us only sky?
Referencing the lyrics of the 1971 song Imagine, released by John Lennon on his Imagine album. The song speaks of all mankind coming together.
Homeless Man: Raphael, like the Ninja Turtle.
Referencing the 1984 American comic books created by Kevin Eastman and Peter Laird, which were spun off into three different television incarnations starting in 1987. They have also featured in movies and action figures. The Teenage Mutant Ninja Turtles are four turtles mutated into giant human-ninja turtle warriors: Leonardo, Donatello, Raphael, and Michaelangelo. Dean made a similar allusion when he heard the angel's name for the first time, in "Free to Be You and Me".
