Sheldon: All right, I suppose I'll go put on my bus pants.
Leonard: What the hell are bus pants?
Sheldon: They are pants one wears over one's regular pants when one sits on bus seats that other people have previously sat on. But perhaps from your lofty heights atop the corporate ladder, you've lost touch with the struggles of the common man.

Howard: Ma, Ma, calm down. Listen to me. I know it says click with the mouse, but on a laptop, the trackpad is the mouse. Now, put your finger on it. Doesn't matter which finger. Good choice. Now move it down to your e-mail icon. Yeah, the little envelope. What do you mean, what does it look like? It looks like an envelope! Fine, you don't like the computer, don't use it! Sure, we can exchange it for a salad spinner. Goodbye!

Sheldon: You know, Leonard, that's actually a valid idea. Very good.
Leonard: Can you say that and not make it sound like I'm a cat who learned how to use the toilet?
Sheldon: No. The two achievements are equally surprising and equally admirable. Though if pressed, I'd have to give a slight edge to the cat.

Sheldon: I'll save you the pain and nervousness of waiting for the answer. I agree to be part of your project. Congratulations.
Leonard: Oh, yay for me.

Raj: You know, if I made more money, I could take time off from work and give pretty girls submarine rides.
Howard: What's that? Some weird sex thing?
Raj: No. You take pretty girls underwater in your private submarine, and you show them fish. Why does everything have to be dirty with you?

Leonard: I checked the App Store. No one is doing handwriting recognition differential equation solving.
Sheldon: Oh, dear Lord, shush.
Leonard: What?
Sheldon: You have so few good ideas, Leonard. And you're just going to spill the beans in front of an outsider?
Penny: Who, me?
Howard: Sheldon, I don't think Penny cares about handwriting recognition-based differential...
Sheldon: (singing over them) The stars at night are big and bright, deep in the heart of Texas.

Leonard: She's not going to steal our idea.
Penny: What idea?
Leonard: We're gonna write an application...
Sheldon: [sings] The prairie sky is wide and high, deep in the heart...
Penny: Okay, stop, stop!
Sheldon: [meekly] ...of Texas.

Sheldon: All right. All right, I'm not going to argue with you. Sheldon Cooper is nothing if not a team player. Dr. Hofstadter, you have the conn.
Leonard: Thank you. I thought we might start by talking about the user interface.
Sheldon: Oh, dear Lord, we're doomed.

Leonard: We're not wasting time with names right now.
Sheldon: I see. Is that decision open for discussion?
Leonard: No.
Sheldon: Is the decision to not discuss it open for discussion?
Leonard: No.

Sheldon: I call for a vote of no confidence and an immediate change in leadership.
Leonard: Oh, Sheldon, stop it.
Sheldon: When in the course of human events, it becomes necessary to dissolve the bonds that tie three competent scientists together...

Leonard: That's enough, Sheldon.
Sheldon: All right, let's get right to the vote. Show of hands all those opposed to Leonard and his reign of tyranny.
Leonard: Okay, that's it. You're fired.
Sheldon: Really? Why?
Leonard: Because you're impossible to work with.
Sheldon: I see. And is that open for discussion?

Leonard: What are you doing?
Sheldon: Oh. Good morning, shoemaker. I think you'll be pleased with what the elves were up to last night.
Leonard: But I fired you.
Sheldon: Oh, I know. I'm now an independent contractor.
Leonard: No, you are now nothing. You have no connection to this project whatsoever.
Sheldon: But I made it better.
Leonard: I don't want it better. I want it my way.
Sheldon: Well, that speaks volumes, doesn't it?

Sheldon: Good morning, friend Howard, friend Raj. I see you gentlemen are enjoying beverages. Perhaps they would taste better out of these.
Raj: "World's Greatest Astrophysicist"?
Sheldon: Don't thank me. You earned it.
Howard: "Howard Wolowitz". Why not "World's Greatest Engineer"?
Sheldon: I'm sorry. I typed that into the label maker, but I just couldn't press enter.

Sheldon: Now, down to business. What would it take for you to abandon Leonard and join me in a rival company? Unless, of course, the mugs are sufficient, in which case, welcome aboard.
Howard: We're not quitting on Leonard.
Sheldon: I understand. And your loyalty is admirable. But what if I were to up the ante?
Raj: What are you talking about?
Sheldon: Monogrammed key chains with a built-in laser pointer. No? How about can cosies emblazoned with our university mascot? Go Beavers!
I'll be back.

Howard: Okay, let's try this one. Spherical Hankel function.
Leonard: Hold on. That's it!
Howard: Eureka!
Raj: Hey, we agreed when it was Eureka time, we were all gonna say it together.
Howard: Fine. Let's say it together.
Raj: No. The moment has passed.
