Raj: Sounds like someone's in there.
Bernadette: My God, what if Sheldon and Amy are getting robbed?
Howard: Or worse, what if they're back early?

Howard: You know, I'm really glad you decided to learn Mandarin.
Sheldon: Why?
Howard: Once you're fluent, you'll have a billion more people to annoy instead of me.

Bernadette: Maybe we should get one of those machines to help her up the stairs.
Howard: You mean a forklift?

Sheldon: Sheldon Cooper does not cry.
Howard: That's true, you'd rust.

Penny: You know, you compared us to the strangest couple we know, and we know Amy and Sheldon, Howard and Bernadette, Raj and his twitchy little dog.

Amy: How's this for a compromise? Make all the schedules you want, just don't tell me about them.
Sheldon: Excellent. I'll create an algorithm that'll generate a pseudo-random schedule.
Yeah, and do you know why it won't be a true random schedule?
Amy: Because the generation of true random numbers remains an unsolved problem in computer science.
Sheldon: Come with me.
Amy: Where are we going?
Sheldon: To the hotel room. And when we get there, I'm gonna need you to say that again, except naked.

Raj: Now it's happening to me. Ooh, I should probably make a list of all the scientific inaccuracies in Mamma Mia 2.
Penny: You're gonna go on live TV and admit you've seen that movie?
Raj: Hey, your husband's the one who took me.
Leonard: Meryl Streep and Cher? Yeah, I saw it.
