Sheldon: All right, we're going to be designing an experiment to look for the annihilation spectrum resulting from dark matter collisions in space.
Raj: Ooh, dark matter. We better bring a flashlight, ha, ha.
Sheldon stares at Raj.
Raj: I was making a joke.
Sheldon: I'm the boss. I make the jokes.
Raj: Sorry, go ahead and make your joke.
Sheldon: This is not the time for joking.

Sheldon: This movie baffles me every time we watch it.
Leonard: What do you mean?
Sheldon: Well, the instructions are very clear. Don't feed the gremlins after midnight. Don't get the gremlins wet. How hard is that?

Leonard: So, what's going on with Raj?
Howard: Well, the good news is, he has no problem with my mother's tur-brka-fil.
Penny: Hard to believe, but go on.
Howard: The bad news is, he says he's getting deported.
Leonard: What do you mean, he's getting deported?
Sheldon: I believe it means that the U.S. Government is going to expel him from the country. He could then either return to his native India, emigrate to another country that's willing to accept him, or wander the high seas as a stateless pirate. Personally, I'd choose pirate.

Howard: Penny, would you mind stepping outside so we can speak to him?
Penny: Ugh, fine. But the man really needs to work on his girl issues.
Sheldon: Another reason to consider a life of piracy. Even today, I understand that's an all-male profession.

Sheldon: And you've continued to take the university's money under false pretenses? Highly unethical for an astrophysicist. Although practically mandatory for a pirate.

Sheldon: Hi, Leonard. Hello, Raj.
Raj: Hello Sheldon.
Sheldon: Forgive me .As you know, I'm not adept at reading facial cues, but I'm going to take a stab here, you're either sad or nauseated.
Raj: I'm sad.
Sheldon: I was going to say sad. I don't know why I hedged.

Sheldon: I'm sorry.
Raj: Me, too. I'm just, I'm a little on edge.
Sheldon: Understandable. Your entire life seems to be crumbling around you, and your future appears bleak at best.
Raj: Thank you.
Sheldon: And you're wrong about Hinduism and cows.

Howard: Hey, Raj, guess what. Professor Laughlin is looking for someone to join the stellar evolution research team.
Raj: You-you're kidding. That's fantastic!
Howard: Come on, what are you waiting for? Call him and set up an interview.
Raj: I'm on it.
Sheldon: That's happy, right?
Leonard: Yeah.
Sheldon: Nailed it.

Sheldon: Anyway, I was thinking about exploring the string theory implications of gamma rays from dark matter annihilations, and it occurred to me that I could benefit-
Leonard: Excuse me, Sheldon, how many reels before the subordinate male protagonist gets to his point?
Sheldon: I'm sorry. If you didn't cheer at my entrance, it's too late to buy into the premise. Anyway, I got some extra money from the head of the department, and Raj can come work for me.

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.

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.

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.

Penny: What's this cartoon called again?
Leonard: Oshikuru: Demon Samurai.
Sheldon: And it's not a cartoon, it's anime.

Penny: I give up. He's impossible.
Sheldon: I can't be impossible; I exist. I think what you meant to say is, 'I give up; he's improbable'.

Leonard: Okay, I know what you're doing.
Sheldon: Really?
Leonard: Yes, you're using chocolates as positive reinforcement for what you consider correct behavior.
Sheldon: Very good. Chocolate?
Leonard: No, I don't want any chocolate! Sheldon, you can't train my girlfriend like a lab rat.
Sheldon: Actually, it turns out I can.
