Raj: What's the worst that could come of this meeting?
Howard: I don't know. They take the invention away, and I get nothing?
Raj: Okay, that's not so bad. You know what happened to the scientists that worked on the Manhattan Project? The government forced them to move to the desert. They had to live in secret, and when Oppenheimer objected to what they made him do, they destroyed his reputation.
Howard: What's the point of that story?
Raj: I just read a book about Oppenheimer, seemed like a chance to show off.

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.

Raj: Can we take a moment to discuss that I just lied to the government for you?
Howard: Yeah, I would not have done that for you.

Sheldon: Do you think your father's doing unspeakable things to my mother?
Leonard: No.
Sheldon: Are you saying that because the things are unspeakable?
Penny: Your parents are old. Anything unspeakable was finished by 9:30.

Bernadette: Love is patient, but it's not gonna put up with all the side chatter, so let's knock it off!
Howard: At least she's yelling at someone else for a change.
Bernadette: Howard!
