Sheldon: Wait, oh, and I just I want to let you know right now that we are not getting married in a church.
Mary Cooper: That's all right, Sheldon. Anywhere Jesus is is a church.
Sheldon: Well, he won't be at our wedding.
Mary Cooper: He's in my heart, so if I'm there, he'll be there.
Sheldon: Okay, well, then, he's your plus-one. You don't get to bring anyone else.

Mary Cooper: Lord, thank You. Even though You can do anything, that was mighty impressive.

Mary Cooper: I am so happy for you two, but I'm not surprised. I've been praying for this.
Sheldon: Well, God had nothing to do with it. It happened because I was kissing another woman, and it made me realize I wanted to be with Amy.
Mary Cooper: More than one woman was interested in you? I might have prayed a little too hard.

Sheldon: I've thought about it, and I really want to spend the rest of my life with Amy. Do I have your blessing?
Stephen Hawking: Well, Sheldon, I think you should make her finger like Saturn and put a ring on it.

Raj: It's for Sheldon and Amy.
Stuart: No way! They're engaged?
Raj: Yeah.
Stuart: Well, that's exciting news. Who would've thought Sheldon and Amy would be the next two to tie the knot?
Raj: Tell me about it. I'm the one who caught the bouquet at Leonard and Penny's wedding.

Stuart: Uh you know, they might like this. Superman and Wonder Woman, it's kind of romantic.
Raj: Hmm. You know what? Why am I buying them a gift? They have love. Screw them and their happiness. What do you have for someone who's bitter and alone?
Stuart: Literally everything.

Dr. Harris: Actually, I do have a question for Dr. Cooper. When Amy first told you about her approach to synaptic tracing, did you think it was gonna revolutionize the field?
Sheldon: Really? That's your question? What are you, Entertainment Tonight?

Sheldon: Those people were in the presence of a world-class mind, and all they wanted to talk about was their own nonsense.
Stephen Hawking: Can you see the irony in that statement? How about now? How about now? I'll wait.

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.

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.

Sheldon: Stephen Hawking is a genius. If he said 'no,' I wasn't going to waste time on her father.

Sheldon: Hello?
Leonard: Oh, hey, where you been? We've been calling you for hours.
Sheldon: Oh, I'm sorry, my phone was on "airplane" mode.
Leonard: Why?
Sheldon: Because I was on an airplane. (makes confused gesture to Amy)

Sheldon: You know what? Let me give you a better question. Here, um, "Dr. Cooper, "I heard you were working on a top-secret project "for the U.S. military. Why don't you tell us about that?" See, that's a great question.
Dr. Harris: Okay, what was that like?
Sheldon: Oh, I can't tell you that, it's top-secret.

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.

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!
