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.

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.
