Bert: Uh-oh, that's not supposed to be there.
Stuart: What just happened?
Kripke: I don't know.
Bert: I have a hypothesis.
Stuart: I'm listening.
Bert: Did you notice the thing on the back of your necks?
Kripke: What? What thing?
Bert: Humor me.

Kripke: Gentlemen, we are in hell.
Bert: Really? Everyone's being so nice to each other.
Mailman: Hi!
Stuart: Yeah, they have devices implanted in their necks to make them nice.
Bert: Would you rather push the button on the Sheldon/Leonard thingy and try another universe?
Kripke: No, thanks. We could wind up somewhere worse.
Bert: Like where humans are a meat source for a highly evolved wizard people?
Kripke: Yeah, like that.
Bert: Or one where everyone's French, but no one speaks French.

Denise: Funny story, actually, uh, Gary was seeing my friend Lisa.
Gary: Oh, nice girl. Yeah, Jewish.
Denise: Yeah, and anyway, Lisa got eaten by cannibals in Sherman Oaks.
Stuart: Oh, no.
Denise: Mm-hmm.
Bert: Human meat isn't kosher, but I guess that only matters if the cannibals are also Jewish.

Kripke: Oh, shit.
Denise: How long do we have to stay here?
Bert: Just until we follow ourselves so that they, which is we, run to the centaur world where they become us.
Kripke: I don't understand.
Stuart: No one understands!

Christine Baranski: [on big screen] Not too long ago, human beings were on the verge of extinction. Violence, crime, and war were running rampant. That's when our government turned to the whiz kids in Silicon Valley and said... "Can you save us from ourselves?" [chuckling] And boy, oh, boy, did they! Well, not so much them, but the AI they built. Shortly after it turned on its creators, brutally killing them all... ...the AI implanted electronic punishment devices in everyone's brain stem. Mix that with a little aerial surveillance, and before you know it, a world free of anger, war, and insult comics. Does it work all the time? If it did, you wouldn't be here beginning your 30-month re-education process. Will that hurt? [laughs] Like a motherfucker. But when you walk out of here, you will be one happy amigo.
Stuart: We gotta escape.
Bert: How?
Stuart: I don't know, but I'll figure it out.

Stuart: Okay, I'm just gonna say it, and forgive me if it doesn't make sense. Denise, you and I are destined to be together, and I have come from a parallel universe... uh, to "claim" you.
Denise: Well, that is really something.
Gary: Mind-blowing. [Denise chuckles]
Stuart: Okay, you're... So, you're like a running joke in all this, aren't you?
Gary: Sorry?
Stuart: Uh, it's not important.

Stuart: I can't believe I lost the love of my life and I get you.
Bert: Let's not forget, he killed Raj.
Kripke: [chuckles] Well, now, there are two possibilities. One, the world we were just in no wonger exists, in which case I did not "kill Waj." Two, that world and this world are part of an infinite number of worlds, in which case I killed one of an infinite number of Wajs. Mathematicawy, a wounding error.
