Amy: So are you feeling okay? No wedding jitters?
Sheldon: No. There is nothing in the world that would stop me from marrying you tomorrow, even me from the future coming back to prevent the wedding and the subsequent birth of a child who will destroy humanity.
Amy: Because if you came from the future, that would mean you already went through with the wedding because you believe that time travel is on a closed loop.
Sheldon: I love you so damn much.

Stuart: Great. So, as two genderless blobs of human flesh, how would you like to go to Sheldon and Amy's wedding with me?
Denise: Oh, Stuart. Look, I appreciate that, but it just might be a little weird, considering you're my boss.
Howard: Guess who's gonna officiate Sheldon and Amy's wedding! Mark Hamill! Luke Skywalker is gonna be at the wedding!
Denise: You'll need to buy me a dress.

Amy: (to Georgie) I like your accent. Sheldon, did you used to sound like that? Can you still?
Sheldon: I can. I will not.

Mark Hamill: Welcome. We are gathered here today in the sight of family, friends and Almighty God.
Sheldon: That's too religious.
Mark Hamill: That lady over there made me say it.
Mary: He heard you, and he can't un-hear you.

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.

Mark Hamill: Anyway, thanks so much. I-I want to give you a reward for finding him.
Howard: (chuckles) Oh, no, I couldn't take your money. It's just an honor to meet you.
Mark Hamill: No. No, please. You don't know what this dog means to me, and I thought he was gone for good. Please? There must be something I can do for you. Anything.
Howard: Oh, you're gonna regret that.

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?

Raj: So, yeah, Mr. Mark? When you were on the, uh, Wookiee home planet, how did you even understand what they were saying?
Mark Hamill: I don't remember ever being on a Wookiee home planet.
Stuart: Uh, actually, Luke was on the Wookiee home planet, Kashyyyk, in the Holiday Special when he helped Chewie get home to his wife.
Mark Hamill: Chewie had a wife?
Stuart: Her name's Malla.
Denise: Wow, that's impressive.
Stuart: Yeah.

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."

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

Mrs. Fowler: This is taking too long. I bet that Sheldon stood my baby up.
Penny: Uh, excuse me. Where-where are you going?
Mrs. Fowler: This whole thing was a big mistake. I'm gonna find Amy and get her out of here.
Penny: ­Sit down!
Mrs. Fowler: Excuse me?
Penny: Sheldon loves Amy, and he would never hurt her on her wedding day or any other day, so park it!
*Mary stands up and starts clapping*
Penny: [to Mary] Oh, you sit down, too.
Mrs. Fowler: Are you gonna let her talk to me like that? Say something!
Mr. Fowler: Thank you.

Georgie: Hey, uh, I got a question. Why aren't there tires on any of those Star Wars vehicles?
Mark Hamill: (chuckles) I'm sure some of them had tires.
Stuart: Actually, they don't. I mean, the HAVw A5 turbo tank has metal gripping wheels, but I wouldn't call them tires.
Denise: You are so hot.

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.

Mary: Let me straighten your tie.
Sheldon: No, no, no, it's all right. It's supposed to be a little asymmetrical. Apparently, a small flaw somehow improves it.
Mary: I can see that. Sometimes it's the imperfect stuff that makes things perfect.
Sheldon: Excuse me. *Sheldon rushes out of the room*
Mary: Case in point.

Mary: Oh, Shelly. I wish your dad could see you now.
Sheldon: Me, too. I miss him.
Mary: He would be so proud of you. I know that I am.
Sheldon: Thank you. I mean, for everything. My whole life.
Mary: Oh. *Mary hugs Sheldon*
