Raj: Well, then why don't we just go to the Galleria and walk around?
Sheldon: I don't need anything at the Galleria. Do you need anything at the Galleria?
Raj: No. We would just walk around and see what's what.
Sheldon: That's a semantically null sentence.

Raj: Please, Sheldon, I'm a young, virile visitor from a foreign land and I need to strut my stuff.
Sheldon: Let me offer you a compromise. Sometimes when I feel stifled and want a change of scenery, I use my imagination.
Raj: Oh, boy.
Sheldon: One of my favorite places to visit is the two-dimensional world described in Edwin Abbott's mathematical fantasy, Flatland.
Raj: I don't want to go to Flatland.
Sheldon: You're only saying that because you haven't been there. I am now a hexagon in two-dimensional space and can only perceive the edges of other objects.
Raj: Oy.
Sheldon: Is that you, Raj? I don't recognize your edge.

Leonard: I hope you're hungry, Bernadette. We're going to a terrific restaurant.
Bernadette: Oh, yeah, I'm starved. When you spend all day in a bio-lab, watching flesh-eating bacteria skeletonize small rodents it really works up an appetite.

Raj: Sheldon, I'm begging you. I want to go to this mixer, and I don't want to go alone.
Sheldon: Well, you're in luck. There's a mixer here in Flatland. Oh, look, there's a sexually attractive line segment, you should chat her up.
Raj: What?
Sheldon: Tell her you're a circle. Flatland gals are all hot for circles.

Raj: Dude, there's so many cool things we could be doing tonight. Look. At the Glendale Galleria, "Put on your best zoot suit, it's a salute to Swing music in the center court near Macy's. 5pm to 9pm", huh, huh? A salute to zoot. Sounds like a hoot.
Sheldon: I'm sorry, Raj, I have no desire to salute any article of clothing tonight. Much less one that's linked to race riots in the 1940s.
Raj: Race riots?
Sheldon: The zoot suit riots.
Raj: Oh. I always thought that was some sort of after-Christmas sale.

Raj: What about me?
Sheldon: Well, I understand there are several types of artificial women. Maybe you should look into that.

Raj: Namaste, white people. Good news! I rented us the four-hour edition of Watchmen.
Leonard: Got it.
Howard: Seen it.
Sheldon: Detailed analysis posted online.

Howard: Listen, before we leave, I should warn you, I'm a passionate man and I tend towards public displays of affection.
Leonard: What are you trying to tell me, Howard?
Howard: There might be some making out in the car or the restaurant, and I don't want Bernadette to feel uncomfortable, so it would help if you and Penny made out, too.
Leonard: Don't worry. We're planning to have sex right on the salad bar.

Leonard: Look at us. Getting ready for a double date with actual women who publicly acknowledge they're our girlfriends.
Howard: Yes, actual women are the best.
Sheldon: I don't understand. What other kind of women are there?
Leonard: Howard, artificial women are your department. You want to take this?
Howard: No, it would just freak him out.

Raj: No, no, no, no! That rate is much too low for what we'd expect from this collision. Do you understand that we're talking about dark matter colliding in outer space?
Sheldon: Of course I understand. And who are you to tell me about outer space?
Raj: I'm the astrophysicist. Astro means space.
Sheldon: Astro means star.
Raj: Okay, well, let me just tell you, if we were having this argument in my native language, I'd be kicking your butt.
Sheldon: English is your native language.

Raj: My god, you think that every thought that comes out of your head is pure gold. Well, let me tell you something. Some of those thoughts are pure caca.
Sheldon: Caca?
Raj: It means doo-doo.

Sheldon: Wait, you have to drive me home.
Raj: How did you get here?
Sheldon: I walked.
Raj: So walk home.
Sheldon: I can't. There's a big dog outside.

Raj: I've reconsidered your offer to let me work with you.
Sheldon: For me.
Raj: Yes, for you. I do, however, have a few conditions. First, at all times, I am to be treated as a colleague and an equal. Second, my contributions shall be noted in all published material. And third, you are never allowed to lecture me on Hinduism or my Indian culture.
Sheldon: I'm impressed, Raj. Those are very cogent and reasonable conditions.
Raj: Thank you.
Sheldon: I reject them all.
Raj: Then you leave me no choice. I accept the job.

Sheldon: I'm sorry, I believe you've misunderstood. I'm not giving you the job. I'm simply affording you the opportunity to apply for it. Have a seat, we'll get started with the interview.
Raj: Wha... you're kidding!
Sheldon: Please.
Raj: All right.
Sheldon: So, that's what you wear to an interview?
Raj: Come on, dude, we've been friends for years.
Sheldon: Oh, pulling strings, are we?
Raj: Sheldon, for God's sakes, don't make me beg.
Sheldon: Bazinga! You've fallen victim to another one of my classic practical jokes. I'm your boss now. You may want to laugh at that.

Howard: Okay, I guess I can hang for a little while. So what are we watching? Sex and the City. Yikes.
Penny: Hey, I happen to love this movie.
Howard: Fine, let's watch it. Maybe all our periods will synchronize.
