Amy: And I think you're forgetting that there are written documents of meat between bread being eaten in China during the Tang dynasty.
Bernadette: (to Howard) You know what, I'll go with you. And then maybe we just go home.

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!

Stuart: Oh, so she's good enough for Howard but not for me?
Howard: Yeah.
Bernadette: Yeah. Go have weird relationships with your own mother and cousin. This is his turf.

Leonard: You don't go into science for the money.
Bernadette: Speak for yourself. Last month my company both invented and cured restless eye syndrome. Ka-ching, ya blinky chumps!

Amy: Sheldon, I have an advanced degree in the study of the human brain, so if my fiancé is a raving lunatic, it's kind of a ding on my reputation.
Sheldon: If leaders just stepped aside every time they didn't have the consent of the governed, what would we have?
Amy: Democracy.
Sheldon: Not on my watch.

Amy: Sheldon, it's the American way, the peaceful transfer of power.
Sheldon: I don't know.
Leonard: Think about Ant-Man.
Sheldon: I'm always thinking about Ant-Man.
Leonard: Michael Douglas had the suit and then he passed it on to Paul Rudd.
Sheldon: Maybe you're right.
Amy: Really? The Ant-Man thing? That's what won you over?
Sheldon: Yes. He got the details right. That's how you use a superhero.

Sheldon: Instead of being in charge, I can be the vocal opposition, criticizing and badgering the president at every turn.
Amy: I think you'll be really good at that.
Sheldon: Me, too.
Leonard: I think I made a huge mistake.
Penny: Me, too.
