Leonard: As Sheldon's best man, I need to inform you that this is not a bachelor party.
Sheldon: And tell them why.
Leonard: Because you're a tiresome scold.
Sheldon: No. It's because a bachelor party is typically a hedonistic blowout where no pleasures of the flesh are denied. I'm not interested in that.
Leonard: How is that not exactly what I said?

Sheldon: Okay, listen. Dr. Wolcott is a brilliant topologist. We need to set some ground rules so that you don't embarrass me. [To Howard] No magic. [To Leonard] No whining. [To Raj] You, just no.
Raj: Hey!
Leonard: Uh, how come he gets to whine?

Doctor Wolcott: Well, um, I don't normally allow strangers into my house.
Raj: But when you do, you-you let them out, right?

Sheldon: So, Dr. Wolcott, in your letter, you said you had a new mathematical approach that would help me conceptualize the dimensions in string theory?
Doctor Wolcott: Uh, yes, yes, yes, yes. But before we get started, I am going to need to collect everybody's phone. Yeah.
Sheldon: Oh.
Leonard: Why?
Doctor Wolcott: Because they're little listening devices, aren't they? Yes, for people to spy on you and steal your work.
Howard: Yeah, what happened to the good old days where if someone wanted to steal your work, they had to hire a prostitute to seduce you?
Doctor Wolcott: Who told you about that?
Howard: Just making a joke.
Doctor Wolcott: Yeah, it's not funny when it happens.

Amy: What? This is my bachelorette party, tea and quilts?
Penny: Well, you said you didn't want anything crazy.
Amy: Yes, but I said it like, "I don't want anything crazy." Which clearly means I wanted something crazy. I mean, is this how boring you think I am?
Bernadette: Penny, she asked you a question.

Bernadette: Hey, we can make bad decisions.
Penny: Yeah. She had two kids back-to-back and I thought you'd like this, so we're off to a good start.

Sheldon: Dr. Wolcott, your work on time is revolutionary.
Doctor Wolcott: I would say thank you, but, in my theory of time, you've already called my work revolutionary, I've already thanked you, and I hate repeating myself, so let's move on.

Leonard: Wait a minute, are-are you saying that time has multiple dimensions, the same as space?
Doctor Wolcott: No. No, I'm not saying it, the math is saying it. Though it is the math that I invented, so, yes, I guess I am saying it.

Leonard: I could spend months up here just going through his math.
Raj: I think Sheldon might.
Howard: Great. Who's gonna tell Amy we lost her fiancee to a madman in the mountains? [Howard and Raj look at Leonard]
Leonard: Hey, I drove.

Sheldon: So, how would this work in the context of a singularity?
Doctor Wolcott: Yes, that's-that's a tricky bit to explain. I assume you're familiar with non-abelian group theory.
Sheldon: Oh, and how. You never forget your first group theory.

Doctor Wolcott: It's a perfect marriage. We focus on our work and send each other cards every year on our birthdays. Hey, wait, what-what month is it?
Leonard: Uh, April.
Doctor Wolcott: Most years. The point is we give each other space. I give her Europe, she gives me South America. That's where she thinks I'm living.

Sheldon: Thank you for bringing me up here. But I think I'm ready to go home now.
Raj: Really? You don't want to stay for dinner and talk more science?
Sheldon: No. No, we better go. I miss Amy. And my phone. [gunshot in distance] Also, I'm from Texas, and I can taste the difference between rabbit and squirrel.

Doctor Wolcott: Dinner! Guys? I can't believe they left without saying good-bye. Wait a minute, what if they stole my work? Wait a minute! What if they were never here at all? Wait a minute! What if they haven't gotten here yet but they're on their way?! I better tidy up.

Leonard: When I said you should make a playlist for the road trip, I meant music.
Sheldon: This is better than music, this is a lecture on nonlinear time.
Raj: Sounds like it's just on regular time.
Sheldon: Yes, but I put it on shuffle.

Raj: If Bruce Banner's driving a rental car and turns into the Hulk, do you think he's covered, or does he need to add the Hulk as an additional driver?
Howard: You really need a girlfriend.
