Howard: This paper is called "Examinations of a Super-Asymmetric Model of the Universe" by Dr. Vasily Gregora-poli-popivich.
Leonard: W-Wait, so Amy and Sheldon weren't the first to think of super-asymmetry?
Howard: No, doesn't look like it. This is from 1978.
Leonard: Okay, well, they might need to rename their theory "The Cooper-Fowler Gregora-poli-popivich Theory."
Howard: Kind of rolls right off your tongue, doesn't it?

Denise: I don't want to blame you, but if you'd moved in with me when I asked you to, we wouldn't be in this situation.
Stuart: You're right. It's my fault. When I had the chance, I was scared and now that I want to, you're stuck with Mitch.
Denise: So you do want to move in with me?
Stuart: More than Galactus wants to devour worlds.
Denise: Well, that's great 'cause I want to move in with you more than the Thing wants to clobber.
Stuart: More than Hulk wants to smash?
Denise: More than Batman wants to ignore the due process of law.
Stuart: We are so weird.

Penny: Listen, when you have kids, I'm still gonna be there. I'm gonna be their fun Aunt Penny who gives them candy, and teaches them swear words and tells them stories about what a weirdo their mother is.
Amy: I guess I could live with that. What is gonna be hard is letting go of the dream of us breastfeeding each other's babies.
Penny: And it's gonna be hard to forget you said that.

Raj: Okay, this citation is correct. How you doing?
Leonard: Pretty good. I'm just looking through "The Effect of High Energy Muons on Proton Pion Scattering at the National Accelerator-" (inhales) "-Laboratory."
Raj: Hey, should we take a break?
Leonard: No, this actually makes it more exciting. We have to get through all of this before I run out of this.
Raj: It's like the movie Speed, but instead of a bus, it's your lungs. And instead of Sandra Bullock, it has sadness.

Penny: All right, great, can we go?
Bernadette: In a minute. I want to show Howard I can play this game.
Penny: You know, you make a lot more money than he does. Can't you just rub his nose in that?
Bernadette: I can, but I want to rub his nose in this.

Penny: Hey, ready for lunch?
Bernadette: Hang on.
Penny: Really, video games? Is this some sort of Freaky Friday thing where you're actually Howard?
Bernadette: Please, if I were Howard, I'd be doing this. [looks down at her breasts] You know what? He's not wrong.

Bernadette: Hi, Stuart, just checking in. Seeing if everything's okay.
Stuart: Oh, yeah, we're having fun. Me, Halley and Denise played hide-and-seek all day.
Howard: Oh, that's nice.
Stuart: Yeah. I found Denise right away.
Bernadette: Where was Halley hiding?
Stuart: Uh, the important thing is she's not there now.

Howard: This one's how you move, this is how you shoot. "A" jumps, "B" puts you into build mode.
Raj: And depending on what you want to build, you can use LB, RB, LT, or RT.
Bernadette: Just put me in, I'll figure it out.
Howard: Oh, sounds like me on our honeymoon.
Raj: Okay, you're skydiving down. You're almost to the ground. Now, when you land, you're gonna want- (gunfire) Okay, you're dead.
Bernadette: Wait, that's it? That wasn't fun at all.
Howard: Oh, now it sounds like you on our honeymoon.

Amy: I guess we should go and let Howard get them ready for bed.
Sheldon: Yeah. Do you think he'd let us come back and do some more?
Amy: Maybe we could take them to the park.
Sheldon: Smart. There'll be more babies. It's a bigger sample size.

Bernadette: What you playing?
Howard: Fortnite. A bunch of people parachute onto an island and fight it out to be the last man standing.
Bernadette: Like Hunger Games?
Raj: More like Bachelor in Paradise, but not as cutthroat.

Anu: I guess if we're going forward with this wedding, we should talk about the next steps.
Raj: Oh, like themes and flowers?
Anu: Actually, finances and taxes.
Raj: Oh. We can't use that. That was the theme of my parents' divorce.

Bernadette: I dunno, I married for love and it turned out ... fine.
Penny: [silence] Oh, yeah, me, too.

Howard: Listen, I did something kind of stupid today.
Bernadette: Okay.
Howard: I went to The Cheesecake Factory to try to figure out who that waitress was.
Bernadette: Howie.
Howard: Don't worry, I didn't find out, because I realized I didn't even care. While I was there, I started asking myself, "Why does this mean anything to me?" And I guess the truth is it was all about my vanity. And why should I need to be validated by another woman liking me when the best woman in the world already loves me? And I just wanted you to know that. [chuckles]
Bernadette: The restaurant manager already called. You really creeped a lot of people out.
Howard: And I regret that. [chuckles] Because the only woman I want to creep out is the mother of my children.
Bernadette: Well, you're off to a good start.

Wil Wheaton: Hey, what are you guys doing here?
Amy: Oh, I, uh, think Sheldon might have left something.
Wil Wheaton: Oh, you mean, besides his lunch?

Amy: I mean, it's sweet that you want to help, but we don't want you compromising your integrity for us.
Sheldon: Wait, what- Really? I thought we were just worried about looking bad.
Amy: It could be both.
Sheldon: Okay. But I'm gonna go with my reason. Yours is too complicated.
