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

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

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.

Mrs. Fowler: I'm surprised Amy didn't pick us up.
Penny: Oh, well, you know, she's pretty busy the day before her wedding.
Mrs. Fowler: Too busy for her mother? She used to be such a devoted daughter. Now she's just waiting for me to die so she can get my china.

Mary: Thank you again for picking us up.
Raj: (chuckles) My pleasure, Mrs. Cooper.
Mary: You know, our driver to the airport was also a Indian fella.
Missy: Mom!
Mary: Oh, so now it's racist to notice when somebody's Indian.
Raj: I don't think it's racist. I noticed you were both white.
Mary: See?

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."

Mary: You'll have to excuse her. She's just pregnant and hormonal.
Raj: Oh, yeah, congratulations on baby number two.
Missy: Yeah. Whoopie.

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.

Mary: Her husband would be here, but he stayed home to watch their older son, so e-everything's fine!
Missy: Stop it. We're separated.
Raj: You don't say?

Penny: All right, Saturday is the big day. A lot of people thought this would never come. I may have been one of those people.
Amy: I may have been one of those people.
Sheldon: Wait, wait, are we talking about the wedding?
Amy: Yes.
Sheldon: Oh, yeah, I was definitely one of those people.

Penny: I'm gonna need everyone's help. Think of this as one of your comic book movies. There's a bunch of superheroes, each with a different task.
Raj: Oh, like the new Avengers.
Bernadette: Which one was that?
Howard: The one you slept through last weekend.
Bernadette: Oh, that was a good nap.

Amy: I think it's more like, uh, like Lord of the Rings, and you're the Fellowship. Uh, someone's got to go to Gondor, someone's got to go to Mordor, someone's got to hold off the demon of shadow and flame.
Leonard: You mean the Balrog?
Amy: I mean my mother.
Sheldon: That is a perfect metaphor, Amy.
Amy: Thank you.
Sheldon: Because it also involves a ring that binds me in servitude forever.
Amy: Aw, he said forever.

Jenna: You might not want to get too close. Pink eye.
Raj: Me, too! Bacterial?
Jenna: Yeah.
Raj: Same! (laughs) I-I know this is gonna sound crazy, but would you be interested in going to a wedding with me?

Sheldon: Why aren't you looking at the camera?
Amy: Oh, you know, I'm just working on my peripheral vision.
Sheldon: Well, that is nonsense. Your peripheral vision is fine. Are those women's magazines making you feel bad about yourself again?
Amy: Yup, that is what's happening.
Sheldon: I have told you before, those women are airbrushed to make it look like they have good vision.

Penny: Hey! I got all the beads to the other side.
Howard: It's not a puzzle, Penny.
Amy: Do you really want to be touching that? Do you know how many sick kids? You know, never mind. Knock yourself out.
