Sheldon: You don't see it, do you? We're losing her.
Leonard: Okay, I'm going to make this very simple for you. You are not in this relationship, I am. Ergo, you have no say in anything that happens between me and Stephanie.
Sheldon: I'm afraid I can't allow that. Pursuant to Starfleet General Order 104 Section A, you are deemed unfit and I hereby relieve you of your command.
Leonard: General Order 104, Section A does not apply in this situation.
Sheldon: Give me one good reason why not.
Leonard: Because this is not Star Trek.

Sheldon: She's sending virtual livestock to random men on the Internet. If I have any hope of keeping them together, I need data. Specifically, I need to know exactly what Leonard did that caused you to pop an emotional cap in his buttocks.
Penny: What?
Sheldon: Again, urban slang. In which, I believe I'm gaining remarkable fluency. So, what is the down and the low? And don't worry, this is all entirely confidential, so, you feel free to include any and all shortcomings in the bedroom.

Penny: Sheldon, what do you want?
Sheldon: I'm certain this will come as no surprise to you, but Leonard is failing in yet another relationship.
Penny: He's having problems with Stephanie?
Sheldon: She's sending virtual livestock to random men on the Internet.

Penny: Sheldon, would you like to come in?
Sheldon: I suppose I could spare a few minutes. (Looking at Penny's apartment) Were you robbed?
Penny: No.
Sheldon: How can you be sure?

Sheldon: More to the point, it's about finding a way to keep Leonard and Stephanie together.
Howard: Oh, I don't think you can.
Sheldon: Well, why not?
Howard: Look at Leonard's record. 27 days with Joyce Kim.
Raj: During which she defected to North Korea.
Howard: Two booty calls with Leslie Winkle.
Raj: For which she awarded him the nickname "speed of light Leonard."
Howard: And a three hour dinner with Penny.
Raj: Which would have been two and a half if they ordered the souffle when they sat down.
Howard: Based on the geometric progression, his relationship with Stephanie should have ended after 20 minutes.

Sheldon: This is Stephanie's Facebook page. Now, where it should say in a relationship, what does it say?
Leonard: Stephanie Barnett is single.
Sheldon: Yeah, furthermore, earlier this evening, she threw a digital sheep at some guy named Mike. Who's Mike? Why does he get a digital sheep and not you?

Sheldon: In fact, I was briefly able to see the inside of my sister's guinea pig, Snowball, before he caught fire. It led to an interesting expression in our house, not a snowball's chance in a CAT scanner.

Sheldon: Penny, hello.
Penny: Hey, Sheldon.
Sheldon: What is shaking?
Penny: I'm sorry?
Sheldon: It's colloquial, a conversation opener. So, do you find the weather satisfying? Are you currently sharing in the triumph of some local sports team?
Penny: What's wrong with you? You're freaking me out.
Sheldon: I'm striking up a casual conversation with you. S'up?
Penny: Please don't do that.
Sheldon: All right, But I'm given to understand that when you have something awkward to discuss with someone, it's more palatable to preface it with banal chit chat.
Penny: So, this wasn't the awkward part?
Sheldon: No.

Sheldon: Hi, Stephanie. I'm sorry I'm late, but your companion left the most indecipherable invitation.
Leonard: What invitation?
Sheldon: "We're going to the movies." What movie? What theater? What time? If you were trying to make it impossible to locate you, you couldn't have done a better job.
Leonard: Oh, clearly I could have.
Sheldon: It took me nearly 20 minutes to go through the browser history on your computer to see what movie times you looked up.

Leonard: Do you understand that this was supposed to be a date?
Sheldon: I do. Do you? Because frankly, you've been in a foul mood since I sat down.

Sheldon: Leonard fairly calls the question, who is in favor of abandoning our game and confronting Penny's steroid-infused ex-boyfriend in a suicidal mission to extract money from him?
Say hi to Kurt for us.
Leonard: Excuse me. When Frodo left the Shire to take the one ring to Mordor, didn't Samwise, Pippin and Merry go with him?
Sheldon: They did.
Leonard: Well?
Sheldon: They had a terrible time of it, Leonard.

Penny: Come on. What about the living organism of the workforce and the American spirit and Jiminy Crockett at the Alamo?
Leonard: Davy Crockett. Jiminy Crockett was a cricket.

Sheldon: Look at Planck's Constant. People say it's arbitrary. It could not be less arbitrary. If it varied even slightly, life as we know it would not exist. Bam! Now, let's reconsider the entire argument, but with entropy reversed and effect preceding cause, so you are thinking of a universe that's not expanding from the center. No, it is retreating from a, from a possibility space. Bam! This is a space where we are all essentially Alice through the Looking Glass, standing in front the Red Queen, and we're being offered a cracker to quench our thirst. Bam! Of course, in another universe, let's call it universe prime, there's another Sheldon. Let's call him Sheldon prime...
Penny: We should have let him go to bed.
Leonard: Bam.

Leonard: I can't believe we actually did it.
Howard: 1,000 friggin' Penny Blossoms.
Penny: I just want you guys to know I am really grateful for your help, and for every dollar I make, I'm going to give you 20 cents.
Howard: That's your entire profit margin.
Penny: Oh. Then never mind.

Sheldon: Okay, that, right there, that equivocation and self-doubt, that is not the American spirit. Did Davy Crockett quit at the Alamo? Did Jim Bowie?
Howard: They didn't quit. They were massacred by, like, a gazillion angry Mexicans.
