Sheldon: We're engaged.
Raj: Oh, my God, that's amazing! Wait, uh, tell me everything.
Sheldon: Well, Dr. Nowitzki was kissing me-
Amy: Okay, you can stop leading with that part of the story.

Bernadette: This wasn't supposed to happen. We were careful.
Penny: Yeah, I didn't even think you could get pregnant while you were breastfeeding.
Bernadette: Well, guess what? You can!

Howard: Look at Nowitzki over there.
Leonard: I can't believe she tried to steal Sheldon from Amy.
Raj: You know what? I'm gonna go there and tell her that they're engaged now and that her little plan didn't work.
Howard: Because you're sticking up for Sheldon, or because you're still mad she rejected you?
Raj: Too far away, can't hear you.

Raj: Hey, Stuart.
Stuart: Oh, hey, Raj. What can I help you with?
Raj: I need to buy an engagement gift.
Stuart: Oh, well, you came to the wrong place.

Bernadette: But then we realized that it's a gift, in the sense that we didn't ask for it, and we may not have chosen it-
Howard: And we already have one.

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.

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.

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.

Amy: But you did ask my father?
Sheldon: I did. He said yes. Although, not in a robot voice, so it wasn't nearly as cool.

Amy: This is my fiance, Dr. Sheldon Cooper. That's the first time I've said that and it kind of gave me the goose bumps.

Dr. Harris: Amy, I recently read your paper on lesions in the olfactory receptors in the brain. It was inspired.
Amy: Oh, well, I guess it didn't stink. But if it did, that rat wouldn't have known it.

Amy: You know what, Sheldon? You're not always the smartest person in every room. You may not even be the smartest person in this room.
Sheldon: Oh, I am sorry. What, is Neil deGrasse Tyson hiding behind the couch? 'Cause if he is, he's not that smart, it's pretty dusty back there.

Bernadette: Obviously, it was a surprise. There was some crying and some yelling.
Howard: Some suggestion of make-up sex that did not go over well, even though it's not like we can get more pregnant.

Raj: It's just it's hard talking to my other friends about this, but I knew you would understand.
Stuart: Why is that?
Raj: Because you and I are both alone, which is actually kind of comforting, because at least we can be alone together.
Stuart: Mm. This is, this is awkward. I, um, I was actually gonna close up a little early tonight 'cause I have a date.
Raj: Really?
Stuart: Yeah.
Raj: (clears throat) Forgive me if I'm having trouble being happy for you.
Stuart: Don't be silly, I'm loving your pain.

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.
