Raj: What time do you and Bernadette head out?
Howard: As soon as I get home. We're hoping to make it before dark.
Raj: I've never been to Palm Springs.
Stuart: Oh, you should go. It's terrific. I really thrive anywhere the women and the temperature are over 90.

Raj: I don't know. If I want to watch old people sweat, I can just FaceTime my family in India.

Stuart: It's nice you and Bernadette are getting away.
Howard: Well, she wants us to spend more time together before the baby comes.
Stuart: So then what are you doing here buying comic books?
Howard: Well, he (Raj) wants us to spend more time together before the baby comes.

Sheldon: Well, as a male, I have an evolutionary drive to perpetuate my DNA. Restricting myself to a single partner is against my nature.
Amy: We sleep together once a year! You want other partners?
Sheldon: Don't blame me. Blame your pal, biology. He's the pervert pulling the strings here.

Amy: You wanna see other people? Go see other people.
Penny: I hope one of those people is a monkey, 'cause this is bananas.
Leonard: Hey, you can make jokes, but if this keeps up, he's gonna move back in here.

Penny: Okay, I'm confused. Which one is Mr. Robot?
Leonard: I'll give you a hint. We're watching Daredevil.

Sheldon: Will you two please inform Amy how much you enjoy adhering to a strict bathroom schedule?
Penny: Can't.
Leonard: Won't.
Penny: Didn't.
Leonard: Don't.

Amy: I told you, you can't regulate every aspect of our lives.
Sheldon: I can if you'd just roll over and accept your fate.
Amy: I'm sorry for bringing this over here.
Penny: Believe me, we know what you're going through.
Leonard: And I think the most helpful thing we can tell you is no backsies.

Sheldon: Well, if you are so protective of the scientific method, perhaps we should use the next five weeks to finish what we started.
Amy: Well, for science, maybe I will!
Sheldon: For science, maybe you should!
Amy: Fine!
Sheldon: Fine!
Amy: Good.
Sheldon: Great.
Amy: Do you want to go to our place and make out?
Sheldon: Does Stephen Hawking roll through the quad?

Amy: What would a theoretical physicist understand about an experiment anyway? I mean, you wouldn't know a confounding variable if two of them hit you in the face at the same time! And you don't even get that joke, 'cause you don't even work with confounding variables!

Sheldon: How dare you.
Amy: Oh, you heard me. Your experimental bona fides are laughable.
Sheldon: Whoa, whoa! Now you're making fun of my bona fides?
Amy: Can't make fun of something that's a null set.
Penny: I feel like I should say "damn!"
Leonard: Do it.
Penny: Damn!

Sheldon: So, how is everyone?
Amy: Miserable and exhausted.
Sheldon: Really? I slept great.
Amy: Well, I didn't, and it's your fault.
Sheldon: How? You had the whole floor to yourself.

Amy: Sheldon, maybe living together is a bad idea.
Sheldon: But what kind of scientists would we be, drawing a conclusion after only 12 hours of data?
Amy: The kind who almost put a pillow over your face last night.

Sheldon: Wow. I anticipated we'd have problems, but I never thought your scientific rigor would be one of them.
Amy: I'm sorry, are you questioning my integrity as a scientist?
Sheldon: If the lab room disposable shoe cover fits.
Penny: Was that a science diss?
Leonard: Yeah.
Penny: Was it a good one?
Leonard: Meh.

Penny: Wow! Where did you learn these moves?
Leonard: The world may have forgotten about Dance Dance Revolution, but not this smooth criminal.
