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.

Sheldon: Greetings, gentlemen. How goes your little project?
Raj: You mean, Project Leonwoloppali?
Sheldon: Ah, a combination of all your names. Very clever. I assume Koothranardowitz was taken?

Penny: What you doing? Trying to contact your home planet?
Sheldon: I'm practicing my theremin.

Penny: Hey, you don't need Leonard and his app. You can make one with me.
Sheldon: With you?
Penny: Seriously, I have a great idea for one.
Sheldon: Is it better than your idea to move to Los Angeles and become a famous actress?
Penny: Okay, look. When you see someone wearing shoes you like, you just snap a picture of them, and the app goes on the Internet to find out where you can buy them.
Sheldon: That's your app idea?
Penny: Well, you don't like it?
Sheldon: I didn't say that. But no, I don't.

Sheldon: Oh, Penny, where do I begin? The simple-mindedness of your idea is exceeded only by its crass consumerism and banality.
Penny: And Leonard didn't want to work with you? Imagine that.

Penny: Sheldon, I'm gonna make some cocoa. Do you want some?
Sheldon: Do you make it with milk or water?
Penny: Milk.
Sheldon: Real cocoa?
Penny: That's what it says on the packet.
Sheldon: Do you have those little marshmallows?
Penny: No, sorry.
Sheldon: Well, I suppose it's appropriate.
Penny: What does that mean?
Sheldon: A disappointing drink for a disappointing day.

Raj: Hey, look at this. Twenty people from the university have already signed up for our private beta.
Leonard: I'm telling you, the Lenwoloppali Differential Equation Scanner meets a real need. We've got a hit.
Raj: What do you think we should sell it for?
Howard: Well, based on the fact that our potential market is about seventy or eighty guys, and you want a submarine, I'd say about a million dollars a pop.
Raj: Well, what if we put out a lite version for half a million? You know, get the word of mouth going.

Penny: Hi. I'm sorry to bother you guys, but you've got to come take your Sheldon back.
Leonard: What's he doing in your apartment?
Penny: Well, he was moping down in the lobby, so I invited him over and now I regret it.
Leonard: Why do you regret - Uh, never mind, stupid question.

Penny: Look, can't you just let him play with you until bedtime?
Leonard: We're not playing. This is real work.
Howard: We're going to be hundred-aires.

Penny: Okay, how about this? You know how you're always trying to learn about sarcasm?
Sheldon: No.
Penny: No?
Sheldon: I was being sarcastic.
Penny: Oh. Good for you.

Leonard: Okay, now that you're back on the team, let's get you caught up.
Sheldon: Before you begin, let me say again how deeply sorry I am for my earlier behavior, and how much I respect and admire your leadership.
Leonard: Thank you. So as you can see, not only can you store your favorite equations, but you can forward them to your friends or post them on Facebook right from the app.
Sheldon: Well, I must say, I am impressed.
Leonard: Thanks.
Sheldon: You all have clearly put in a lot of hard work.
Howard: We have.
Sheldon: As a result, you have taken the most important step on the road to success, learning what not to do. Now, let's start fresh. Howard, we're going to need some tea.

Penny: Okay, these are Uggs. These are Crocs. These are knockoff Manolo Blahniks.
Sheldon: Bored.
Penny: Look, you said it yourself, we have to create a database before you can write an alga-thingy.
Sheldon: Algorithm. You see, Penny, Alan Turing defined an algorithm...
Penny: Bored.

Raj: I think we should take a picture to capture this moment.
Leonard: Yeah! (Fart noise)
Raj: Was that the best 99 cents I ever spent, or what!
