Howard: You still feel good about leaving them with Stuart and Denise for a couple days?
Bernadette: I guess. I just hope we don't miss Michael's first words.
Howard: Or Stuart's last words.

Leonard: Excuse me, but if I recall, you're the one who went out drinking with Sheldon, then came home and attacked me.
Penny: Attacked you? I said, "Do you wanna?"
Leonard: Yeah. I was helpless.
Penny: Uh-huh.
Leonard: So do you wanna?
Penny: Well, I can't get more pregnant.
Leonard: Mm-hmm. We'll see about that.

Sheldon: All right, bagels down. Before we head to the airport, I'd like to go over a few things.
[others groan]
Sheldon: From the moment we step off the plane, each and every one of you is an ambassador for Amy and myself.
Howard: [to Bernadette] I told you these tickets weren't free.

Howard: Somebody just peed in the big girl potty.
Bernadette: Oh, I'm so proud! It was her, right?
Howard: Yes.

Sheldon: Yes. And a reminder, Penny, there's free alcohol in business class, don't abuse it.
Penny: Relax. I'm not gonna drink.
Bernadette: Why? You pregnant?
Penny: Wha-? [laughs] No. No, I just, you know, I don't like to drink when I fly.
Bernadette: Please. I've seen you drink in the shower.
Howard: You guys have showered together?
Bernadette: Sometimes you're just ech.

Sheldon: Yes, Penny?
Penny: Oh. Do we have to go?

Leonard: [answering the phone] Hello. Hey. It's Howard. Oh, us, too.
Penny: Wait, what?
Leonard: They're gonna stay. The kids are fine. Bernie's parents took over. Really? Oh, poor little guy.
Penny: Is Michael okay?
Leonard: Yeah, it's Stuart. Bernie's dad gave him a hug, cracked a rib.

Sheldon: "Your majesties, members of the Nobel Academy. When I was a young boy growing up in East Texas I always knew I'd wind up on this stage, and everybody who said I wouldn't looks pretty darn foolish right now. I'm talking about you, high school science teacher Mr. Hubert Givens."
Amy: Sheldon, Sheldon. Why are you talking so fast?
Sheldon: I'm trying to get my speech down to 90 minutes.
Amy: Nobody's gonna be able to understand a word you're saying.
Sheldon: Welcome to my life.

Leonard: How long is it gonna take you to get ready?
Penny: Oh, I just need, like, five or ten minutes.
Leonard: Really?
Penny: No. What is wrong with you?!

Sheldon: Carbon. Hydrogen. Carbon. Carbon. And last but not least, carbon.
Leonard: This might be the glue talking, but that was a very pleasurable 139 and a half hours.
Sheldon: Agreed.

Leonard: Are you kidding me? You just found out that a woman who has loved and cared for you for 12 years is pregnant, and all you can say is you're relieved that she's not gonna get you sick?
Sheldon: There's no need for a recap. I was there.

Amy: Thank you, your majesties. Thank you to the Nobel Committee. We are deeply honored. I would just like to take this moment to say to all the young girls out there who dream about science as a profession: go for it. It is the greatest job in the world. And if anybody tells you you can't, don't listen. And now, speaking of not listening, my husband, Dr. Sheldon Cooper.

Sheldon: All right, well, we should head out now if we're gonna get to the airport six hours before boarding.

Raj: And please, if you have any problems, any questions, call me immediately, okay?She's my baby.
Bert: It shouldn't come up, but just in case: where could I buy a dog that looks exactly like her? Kidding. If she dies, I'll just tell you.

Sheldon: Uh-oh. That's the fourth time she's been to the bathroom in the last two hours.
Amy: So?
Sheldon: Her breakfast was binding. I made sure of that.
Amy: So?
Sheldon: So she clearly has some sort of stomach distress. If it's viral, we're all susceptible.
Amy: She's probably just airsick.
Sheldon: Yeah, but what if she's not? What if we get what she has? What if we infect the King of Sweden? That's how wars start. [Penny leaves the bathroom and instantly heads back] All right, that's it, this is Outbreak and she's the monkey.
Amy: [faintly] Wait. Stop. Be reasonable.
