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.

Sheldon: I believe I'm hearing some negativity on the factory floor.
Penny: So?
Sheldon: Penny, the labor force is a living organism that must be carefully nurtured. Any counterproductive grumbling must be skilfully headed off by management. Observe. Hey! Less talk, more work!
Penny: Nicely done.
Sheldon: Thank you. You hear any union talk, you let me know.

Leonard: Sheldon, we still have 380 of these things to make.
Sheldon: I have complete faith that you will make them. Good night.
Penny: Leonard?
Leonard: Yeah, no. But, Sheldon, without your insight and leadership this entire enterprise will surely fail.
Sheldon: You're right, of course.

Penny: Here, this will help.
Sheldon: Very well, but if this leads to opiates or hallucinogenics, you're going to have to answer to my mother.

Sheldon: Of course, but before we set up a marketing and distribution infrastructure, we should finish optimizing the manufacturing process. To start with, she has a terrible problem with moisture-induced glitter clump.
Penny: Yeah, it's a bitch.
Howard: Uh, I've seen this before.
Leonard: Where?
Howard: It's a common stripper problem. They dance, they sweat, they clump.

Leonard: Are you thinking about adding a desiccant like calcium sulphate?
Howard: Actually, I'm thinking about this one stripper named Vega. But sure, calcium sulphate could work.
Sheldon: Let's think out of the box for a moment. How about a molecular sieve?
Leonard: Oh!
Penny: I've got a spaghetti strainer in the kitchen.
Sheldon: Wow.

Sheldon: All right, ten dollars a day times five days a week, times 52 weeks a year is two thousand six hundred dollars.
Penny: That's all?
Sheldon: Before taxes.
Penny: Well, I don't have to pay taxes on this stuff.
Sheldon: I believe the Internal Revenue Service would strongly disagree.

Penny: Sheldon, don't you get it? If this takes off, I won't have to be a waitress anymore.
Sheldon: But then who will bring me my cheeseburger on Tuesday nights?
Penny: Another waitress.
Sheldon: What's her name?
Penny: I don't know.
Sheldon: And you're going to let her handle my food?
Penny: Nancy. Her name is Nancy.
Sheldon: I think you're just making that up.
Penny: Sheldon, I'm sorry about your hamburger, okay? I just don't want to be a waitress for the rest of my life.
Sheldon: Cheeseburger. I get a cheeseburger.
Penny: Fine, cheeseburger.
Sheldon: Maybe I'd be better off with Nancy.

Sheldon: Bailment describes a relationship in common law where a physical possession of personal property, or chattels, is transferred from one person, the bailor, to another person, the bailee.
Penny: Yeah, yeah, yeah, yeah. Look, look, look. I started a business.
Sheldon: Obviously, not a cleaning business.

Sheldon: Just to be clear here, you're asking for my assistance.
Penny: Yes.
Sheldon: And you understand that will involve me telling you what to do?
Penny: I understand.
Sheldon: And you're not allowed to be sarcastic or snide to me while I'm doing so.
Penny: Okay.
Sheldon: Good. Let's begin with the premise that everything you've done up to this point is wrong.
Penny: Oh, imagine that.
Sheldon: Sarcasm. Good-bye.
Penny: No, sorry. Wait, please come back.

Howard: Too bad. You know the rules of Secret Agent Laser Obstacle Chess. Leonard died again, Sheldon. You're up.
Sheldon: Despite my deep love of chess, lasers and aerosol disinfectant, I must forfeit.
Leonard: Why?
Sheldon: Because it's almost eleven o'clock.
Leonard: So?
Sheldon: So ... Penny has a don't knock on my door before eleven o'clock or I punch you in the throat rule.

Sheldon: Yeah, provided he has already read Infinite Crisis and 52, and is familiar with the re-establishment of the DC multiverse.
Penny: What's a multi-verse?
Sheldon: Get her out of here.

Sheldon: Your robot is inferior and it will be defeated by ours because ours exceeds yours in both design and execution. Also, I'm given to understand that your mother is overweight.


Raj: Oh, snap.


Sheldon: Now of course if that is a result of a glandular condition and not sloth and gluttony, I withdraw that comment.


Raj: What difference does it make, fat is fat.


Sheldon: There are boundaries!

Sheldon: Did you remember to ask for the chicken with broccoli to be diced, not shredded?
Penny: Yes.
Sheldon: Even though the menu description specifies shredded?
Penny: Yes.
Sheldon: Brown rice, not white?
Penny: Yes.
Sheldon: You stop at the Korean grocery and get the good hot mustard?
Penny: Yes.
Sheldon: Did you pick up the low sodium soy sauce from the market?
Penny: Yes.
Sheldon: Good. See how it's done, Leonard?

Leslie: Hey, are you enjoying that prototyper I got you?
Howard: Oh, it's great. Everybody in the Engineering Department is eating their hearts out.
Leslie: Isn't it nice when your good fortune makes others miserable?
Howard: You know, most people don't get that.
