Mark Hamill: We're here to celebrate the marriage of Sheldon Lee Cooper and Amy Farrah Fowler. I had more prepared, but I'm just gonna skip to the rings and vows, since I've been answering your questions for 45 minutes.
Stuart: Yeah, he answered 'em.

Sheldon: Amy, you said something about my bow tie that I can't stop thinking about.
Amy: Don't you mean (in a Southern accent): "Y'all said something 'bout my bow tie"? Go on, say it. Say it.

Stuart: Hey, dude.
Denise: Dude?
Stuart: Yeah, you know, just want you to know that I don't think of you as a woman.
Denise: Oh, perfect. I don't think of you as a man.

Amy: Sheldon, when I was a little girl, I used to dream about my wedding. But, eventually, I stopped, because I thought that day would never come. And then I met you. From the first moment in that coffee shop, I knew that there was something special between us, even though I did work on a study that disproved love at first sight.
Sheldon: I loved that study the moment I read it. Ironic, huh?
Amy: Clearly, it was wrong. Because I felt something that day, and those feelings have only gotten stronger with time. I can't imagine loving you more than I do right now.
But I felt that way yesterday and the day before yesterday and the day before that.
Sheldon: Is that growth linear or accelerating?
Amy: Accelerating.
Sheldon: Oh, maybe we could graph it out.
Leonard: Save something for the honeymoon.
Sheldon: Smart.
Amy: Sheldon, I don't know what the future holds, but I know that I've never been happier than I am in this moment marrying you.

Mark Hamill: Well, that was unexpectedly beautiful. (sniffles) I might need a minute.

Barry Kripke: At wast, my wove has come awong, my wonewy days are over, and wife is wike a song, oh, yeah.

Penny: What are you lunatics doing?!
Amy: Sheldon had a breakthrough.
Sheldon: Actually, Amy and I had a breakthrough.
Penny: Oh, science? Shocking!
Leonard: You don't understand. This could be really big.
Sheldon: No, Penny's right. We have our whole lives to do science together.
Amy: Let's get married.
Penny: All right. It's go time! I am pumped!

Amy: So, you're Sheldon's big brother.
Georgie: Uh, yeah. He got the brains. I got the bod. (chuckles) And the face and the hair.

Sheldon: Are you having an allergic reaction to my boutonniere?
Leonard: No. I'm just so happy for you. And for me. After today, you are officially - and, more important, legally - Amy's problem.
Sheldon: Don't be silly, Leonard. I will always be your problem.

Amy: It's so nice to meet you.
Missy: ­Aw.
Amy: I've always wanted a sister.
Sheldon: Really? Why?
Missy: I love you, too, Sheldon.
Leonard: Really? Why?

Penny: Uh, Mr. Fowler, are you okay back there? Do you need more air?
Mrs. Fowler: He's fine.

Howard: Welcome, Bert. Don't you look nice.
Bert: Yeah. Like a geode, I clean up good.
Howard: Don't you crack a geode open?
Bert: It's not a perfect metaphor.

*Howard answers his front door*
Mark Hamill: Hi.
Howard: I'm gonna need a minute. [closes the door] That's Mark Hamill!

Raj: W-What is he doing here?
Howard: I found his dog and guilted him into officiating the wedding. Don't tell Sheldon. It's a surprise.
Raj: Wait, I-I thought Wil was officiating the wedding.
Howard: Yeah, so did he.
Raj: How did he take the news?
Howard: I'll let you know.

Amy: That was Wil Wheaton. He's really excited about tomorrow.
Sheldon: As am I. If you'd have told me as a child that an actor from Star Trek would be officiating my wedding, I would've said, "Ooh, William Shatner?" And if you'd have said, "No, Wil Wheaton," I'd have said, "Well, did you even try William Shatner?" And if you'd have said, "Yes, but he costs too much money," I'd have said, "Ah, well, Wil Wheaton's good, too."
