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

Mark Hamill: Do you (clears throat)- Do you-
Wil Wheaton: Hey, I'm just saying, I'm here if you need me to step in.
Mark Hamill: No, no, no. I got this.

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?

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.

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

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

Bernadette: What the hell is that?
Howard: Come on, you know this one. It's a dog. I found him in the backyard. And don't worry, I already called the owner.
Bernadette: Good, 'cause we don't need a dog. We already have two babies, you and Stuart.

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

Amy: Sheldon, you're awfully quiet. Are you okay?
Sheldon: Oh. Oh, I'm sorry. I was thinking about string theory. But catch me up.
Mrs. Fowler: What'd I miss? Are you seeing this, Larry? These are the people I'm gonna have to live with after you're dead.

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.

Sheldon: Leonard. That's Mark Ha-Ha-Ha. It's-it's Mark Hami-Ha-Ha-
Leonard: Yep. Thank Wolowitz. He set it up.

Sheldon: There's something I need to tell you. Wow, you look amazing! That's not what I need to tell you. But you do!
Amy: What's wrong?
Sheldon: Something incredible just happened. Remember when you were telling me about my bow tie and how a little asymmetry is good?
Amy: Yeah?
Sheldon: My equations have been trying to describe an imperfect world, and the only way to do that is to introduce imperfection into the underlying theory.
Amy: So, instead of super symmetry, it would be super asymmetry?
Sheldon: (gasps) Super asymmetry. That's it! Give me your lipstick.
Amy: What?
Sheldon: Just give it to me, you beautiful thing! We have work to do!

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.
