Bernadette: Well, Sheldon, I'm pregnant.
Sheldon: Congratulations. How far along are you?
Bernadette: About three months.
Sheldon: Only three? Good gravy, how many babies are in there?

Howard: Okay, let's talk about something that won't infuriate my pregnant wife.
Raj: I read an interesting fact about elephants.
Howard: Try again.

Leonard: Oh, I've got something. I'm being interviewed on public radio this Friday.
Howard: Oh, cool. How come?
Leonard: Uh, the university is trying to get more funding for the physics department, so they want me to go out and talk it up.
Sheldon: Really? You? (Amy whispers to Sheldon) Well, they picked the right person for the job.
Leonard: Thank you.
Sheldon: (To Amy) I think he bought it.

Sheldon: Anyway, I'm proud of you. And I'm going to try to do a better job of sharing the spotlight because we're a team. You know? Much like the Dodgers. If they had superpowers, and fought crime. And Thor was in them.

Sheldon: You know, maybe, um, I should start right now, and go back to Pasadena and let you have this experience to yourself.
Amy: You just want to go back 'cause that's where everybody makes a fuss over you.
Sheldon: You know, your colleagues are right, you are brilliant.

Howard: Oh, let me see the ring.
Leonard: Ooh, nice.
Sheldon: Hey, her eyes are up there.

Raj: This is going to be the biggest smackdown since my Aunt Noopur showed up at the family reunion wearing the same sari as my cousin Sruti.

Amy: Dr. Nowitzki?
Ramona Nowitzki: Oh. Dr. Fowler. Um, hello.
Amy: Thank you. Thank you so much.

Leonard: Uh, Surprise!
Penny: Oh, crap. Is it our anniversary?
Leonard: No. Wait. No.

Penny: All right, so what are we celebrating?
Leonard: Well, you know, Bernadette and Howard are pregnant again, and Amy and Sheldon are getting married. I didn't want you to feel left out.
Penny: Left out? Well, Bernadette has to grow a baby inside of her, and Amy has to marry one. My life is great.

Leonard: So do you not want the cake?
Penny: Try and take it away, see what happens. (Penny starts eating as Leonard checks his phone).
Leonard: Oh, crap, it is our anniversary.
Penny: (Her mouth covered in chocolate cake) Happy anniversary!

Sheldon: Amy, there's something I need to say to you.
Amy: I'm listening.
Sheldon: I've been thinking about the Avengers.
Amy: I believe that. But I don't think that's something you needed to say to me.

Sheldon: I realized that Iron Man is great. And also, that Captain America is great. And sometimes, Iron Man is in a Captain America movie, and he's not mad it's not an Iron Man movie. You know, he can fly in, give the audience a thrill, and then fly away. And that should've been me tonight. I should've been the delightful cameo in your movie.
Amy: Thank you, Sheldon.
Sheldon: Instead, I was like the Hulk, and I-
Amy: Okay, please stop talking about the Avengers.

Penny: You know, whenever I find a top I like, I always go back and get a second one in a different color. Which I hope is not the case with your baby.

Bernadette: Do it! Have a baby, do it!
Howard: Come on, it'd be so cute, our kids playing together? What do you say, why don't you two hit the old mattress and whip up a family?
Penny: Okay, we're not gonna have a baby just to make you guys feel better.
Leonard: Yeah, if we're gonna have a baby it's gonna be when we are ready, or when I'm certain Penny is gonna leave me.
Penny: Exactly.
