Bernadette: Hey, you know who went out on a date the other night? Stuart.
Penny: Oh, good for him.
Bernadette: I thought so, too.
Penny: So is she, like, homeless, or framing him for a crime?

Leonard: This is cool. When was the last time you and I built something together?
Howard: Scientifically? A little over a year ago. LEGOs? Last week in my room.
Leonard: If there was a Nobel Prize for Millennium Falcons that fall apart when you pick them up, we'd be set.

Amy: Sheldon, why don't you get a new computer? You know that one's out-of-date.
Sheldon: Oh, but I like this computer.
Amy: The video is failing, and the sound is cutting out.
Sheldon: I'm sorry, I didn't get that.
Amy: The video is failing, and the sound is cutting out.
Sheldon: I'm sorry, one more time. The sound is cutting out. (Amy holds up a sign) I can't read that. The video is failing.
Amy: Get a new computer.
Sheldon: What?
Amy: Get a new computer.
Sheldon: What? (Answering phone) Hello?
Amy: Get a new computer!

Penny: Well, so how does it work?
Stuart: Ah, well, it shows me all the single women in a five-mile radius who are using the app. If I like the way they look, I hit thumbs up. If I don't, thumbs down.
Bernadette: Oh, what would make you give a girl a thumbs down?
Stuart: First time it happens I will let you know.

Leonard: Oh, hey. I just heard back from the liquid helium guy.
Sheldon: What'd he say?
Leonard: He's got what we need and can meet us tonight.
Sheldon: Oh, really? You know I don't like buying things at night.
January 7, 2009. I went to the Ralph's at 11:30pm to pick up Cracklin' Oat Bran for the morning, and what did I see?
Leonard: The man restocking the cereal shelves.
Sheldon: That's right. And what did he do?
Leonard: He handed you the box directly and called you Stretch.
Sheldon: (shudders) It's like it was yesterday.

Raj: Dude, if we do this, we're gonna need a cool band name.
Howard: You know, I've actually had one I've been sitting on for years.
Raj: Really?
Howard: It was for this power trio I tried to put together in junior high, but I was short two friends.
Raj: What is it?
Howard: Footprints on the Moon.
Raj: I just got chills.
Howard: So did I.
Stuart: Me, too. But I might have Lyme Disease.

Leonard: They've been out there a while.
Amy: I hope everything's okay.
Sheldon: I wonder what they're talking about.
Penny: (eavesdropping at the door) If you guys would shut up, I could tell you.

Raj: Hello?
Claire: Hey, Raj. It's Claire. How are you?
Raj: Hi. I'm good. Really good.
Well, I don't know why I said "really good." I'm just regular good. I really just wanted to sound confident. And that "really" was a real "really", not a fake "really" like the first "really."
Claire: Really?
Raj: I don't know. I lost track and I missed my exit.

Raj: You can't let this stop you. Almost any scientific advancement can be used for destructive purposes.
Amy: It's true. Even Einstein's theory of relativity was later applied to the development of nuclear weapons.
Penny: E equals MC squared. Yeah. E is for energy, M for mass, and C for the speed of light.
Amy: How do you know that?
Penny: Oh, Leonard mumbles it when he wants sex to last longer.

Bernadette: And how many guys have you gone out with?
Stuart: Please be less than two.
Amy: Three.
Stuart: Damn it.

Elon Musk: You think you might ever get back out to space?
Howard: Is that a job offer? 'Cause I really want to go to Mars. Assuming I can bring my wife. She hardly takes up any room. She's basically a carry-on.
Elon Musk: Well, we're not quite there yet, but we're always looking for engineers.
So let me give you my e-mail. We can stay in touch.

Zack: So what's your invention?
Howard: Well, we're using quantum vortices to replace gyroscopes in guidance systems.
Leonard: What's neat is that they can maintain angular momentum indefinitely.
Zack: Angular momentum. I was wondering about that.

Sheldon: Penny, you spent some time in front of the camera. Any words of advice?
Penny: Yes. Don't take your shirt off just because the director said so.
Sheldon: This is a documentary about Mr. Spock. I'm sure if there's nudity, it will be tasteful.

Sheldon: Your name is Bernatrix. You are a warrior queen. You're strong, beautiful and tall.
Bernadette: Oh. I like the idea of being tall.
Sheldon: I think you're gonna like a lot of things I have in store. For example, in this world, only the men get pregnant, so your husband is home trying not to pee when he laughs.
Bernadette: This is getting fun. What's next?
Sheldon: You're parched and weary from battle. You stand in front of a tavern that serves the coldest, most delicious ale in all the realm.
Bernadette: Oh, I haven't had a drink in months.
Sheldon: What do you do?
Bernadette: I storm in, slam my sword down, and say, barkeep, bring me the strongest ale you have and serve it in the skull of a goblin.
Sheldon: He wants to see I.D.

Penny: Thank you so much for helping us, Stuart.
Stuart: Oh, I was just glad to be invited. To be honest, I don't always feel like I'm part of the group.
Penny: Okay, sweetie, we're on the clock here. Can you hate yourself and frost at the same time?
