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.

Leonard: Oh, don't slam the-
Sheldon: Don't slam the [gasps] That was exhilarating.

Sheldon: What would you like me to say?
Leonard: How about congratulating us?
Sheldon: Are congratulations even in order? I didn't think Penny wanted children.
Leonard: Well, she didn't, now she does. And just so you know, we weren't gonna tell anybody so we wouldn't upstage your big day.
Sheldon: Oh, please, you couldn't upstage us. We won a Nobel Prize. Any idiot can have a baby.
Howard: Hey. What's going on?
Sheldon: Case in point.

Raj: Just remember, you're in charge. Don't let her pull you.
Bert: That seems like an unnecessary thing to say.

Amy: Sheldon.
Sheldon: What? Did you finish? Great job.

Sheldon: Well done. You know, you're proving to be an invaluable part of my entourage.
Leonard: Cool.

Penny: Okay, that's it for the fish. We'll be back with the meatballs after a short word from our sponsor.

Sheldon: Thank you, Dr. Fowler. I have a very long and somewhat self-centered speech here. But I'd like to set it aside.
Penny: Yeah!
Howard: Way to go!
Sheldon: Because this honor doesn't just belong to me. I wouldn't be up here if it weren't for some very important people in my life. Beginning with my mother, father, meemaw, brother and sister. And my other family, who I'm so happy to have here with us. Is that Buffy the Vampire Slayer? I was under a misapprehension that my accomplishments were mine alone. Nothing could be further from the truth. I have been encouraged, sustained, inspired and tolerated not only by my wife, but by the greatest group of friends anyone ever had. I'd like to ask them to stand. Dr. Rajesh Koothrappali. Dr. Bernadette Rostenkowski-Wolowitz. Astronaut Howard Wolowitz. And my two dearest friends in the world, Penny Hofstadter and Dr. Leonard Hofstadter. I was there the moment Leonard and Penny met. He said to me that their babies would be smart and beautiful. And now that they're expecting, I have no doubt that that will be the case.
Penny: Thanks, Sheldon. I-I haven't told my parents yet, but thanks.
Sheldon: Oh. I'm sorry. Don't tell anyone that last thing. That's a secret.
Howard, Bernadette, Raj, Penny, Leonard, I apologize if I haven't been the friend you deserve. But I want you to know in my way, I love you all. And I love you. Thank you.

Howard: I was just looking at the map. Couldn't help thinking: we're here and they're there, and if anything happened, we'd have to go here to get all the way back there.
Bernadette: Why are you trying to freak me out?
Howard: This is our vacation. I thought we should do things together.

Leonard: You pick up your dresses?
Amy: Yep. The tailor had to take mine in and let Penny's out. Best day of my life.
Sheldon: What about the day you met me?
Amy: I stand by my statement.

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.

Amy: Do you want to go back to the apartment and see me try on my dress?
Sheldon: Shouldn't I see it for the first time at the Nobel ceremony?
Amy: It's not a wedding.
Sheldon: Okay. Well, give me a minute to think of another reason I don't want to see it.

Sheldon: Well, I hate to say it, but I think everyone is being incredibly selfish.
Amy: Well, you would be the authority on the subject.
Sheldon: What does that mean?
Amy: Sheldon, no one is happier than I am to win the Nobel. But it's not more important than our friends.
Sheldon: How can you call them friends when they're abandoning us?
Amy: They're abandoning us because you broke their hearts.
Sheldon: I didn't mean to.
Amy: I know! You never mean to. That's the only reason people tolerate you!
Sheldon: Does that include you?
Amy: Sometimes, yeah.

Sheldon: Leonard we need to do something about your wife.
Leonard: What's the matter?
Sheldon: She is clearly sick, and she's gonna take us all down with her.
Leonard: She's not sick, Sheldon.
Sheldon: She is, and I'm gonna catch it, and it's gonna ruin the greatest day of my life.
Leonard: I promise you're not going to get what she has.
Penny: What's going on?
Sheldon: [gasps] Unclean! Unclean!
Penny: What?
Leonard: He thinks you're sick.
Penny: Oh. Should we tell him?
Leonard: Well, if we don't, he might try and jump out of the plane.
Penny: Yeah. Doesn't answer my question.
