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.

Raj: Oh man, first monster I see I'm gonna sneak up behind him, whip out my wand and shoot my magic all over his ass!
Stuart: Do you hear yourself when you say these things?

Raj: Amy, good luck getting these guys excited about a dinner with a theme. I gave up when no one cared about my Tom Hanks-Giving.

Penny: What do you mean new roommate? What happened to Leonard?
Sheldon: The same thing that happened to Homo Erectus. He was replaced by a superior species.
Raj: I'm the new homo in town.

Sheldon: I'm not saying that all senior citizens that can't master technology should be publicly flogged. But, if we made an example of one or two it might give the others incentive to try harder.

Raj: Last night I had a dream we got so rich from the app, you and I bought matching side by side mansions, but there was a secret tunnel connecting your front yard to my back yard. What do you think that means?
