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: 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: 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.

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

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.

Missy: Hey, Shelly.
Sheldon: I'm so glad you made it, Missy. This is my fiancée, Amy. Amy, this is my sister. If I ever need a kidney, this is where you get it.

Leonard: Everyone's waiting. What are you guys doing?
Amy: Super asymmetry.
Leonard: Super asymmetry? Is that a thing?
Sheldon: We're inventing it right now.
Leonard: Don't you think this can wait until - Hold on. This is interesting.

Amy: Why do you keep tying and untying that bow tie?
Sheldon: I can't seem to get it even.
Amy: Well, I don't think it's supposed to be even. Sometimes a little asymmetry looks good. In the Renaissance, they called it "sprezzatura."
Sheldon: The Renaissance? Amy, you know I'm more of an Enlightenment person. At some point, we have to decide how we want to raise the children.

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

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.

Mark Hamill: Thank you so much for finding this guy. Oh, my goodness. Hey, Bark.
How are you, buddy?
Howard: Y-Your dog's name is Bark?
Mark Hamill: Yeah.
Howard: Bark Hamill?
Mark Hamill: Yeah. Well, I let the fans name him online. I got lucky, though. He was almost Honey Baked Hamill.

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.

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.

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.

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.
