Raj: Is it even possible to get this done in two months?
Howard: Well, maybe. I don't know. We'll have to work twelve hours a day, seven days a week.
Leonard: Which means I won't be able to make Penny breakfast every day, and she'll realize my brioche French toast was the only thing keeping her in the marriage.
Howard: I love your French toast.
Leonard: Oh, thanks, man.

Leonard: What would you be if you were attached to another object by an inclined plane, wrapped helically around an axis?
Sheldon: Screwed?
Leonard: There you go.

Sheldon: This song is never going to stop. Have you ever dealt with something so relentlessly irritating?
Leonard: That's a trick question, right?

Leonard: My point is, while you're spending all this time on your own, building computers or practicing your cello, what you're really doing is becoming interesting. When people finally do notice you, they're gonna find someone a lot cooler than they thought. And for those of you that were popular in high school, it's over, sorry. Thank you. Congratulations.

Bernadette: I had a plan. I kept leaving Dove bar wrappers around to explain any weight gain.
Amy: Where did you get empty Dove bar wrappers?
Bernadette: From all the Dove bars I ate! I'm pregnant! Try to keep up!

Bernadette: Do you know what? It's just a research project. The most important job in the world is gonna be raising this child. It's all I need to give my life meaning.
Penny: Oh, that's so beautiful.
Bernadette: You believe me? Oh, good. Eleven more chumps like you, I'll have the jury eating out of my hand.

Sheldon: I don't understand why I can't talk at this meeting.
Leonard: 'Cause when you talk, it enrages people.
