Anu: Should we go get changed?
Bernadette: Yeah. Hang on a second.
Anu: What?
Bernadette: Just-- I have two babies at home. What am I doing?
Anu: If you don't want to do this, then why'd you come?
Bernadette: To prove to Howard that he doesn't know me as well as he thinks he does.
Anu: Looks like he does.
Bernadette: Unless I do it and then he doesn't.
Anu: Why not just be honest?
Bernadette: You're right. I should be honest. You owe me $3,000 for those plane tickets to India!

Howard: I'm sorry I didn't take you to the airport. I just want you to know I'll never forgive myself for being so selfish. And I promise to keep you close for the rest of my life.
Bernadette: Oh, no, that thing's gonna end up in my bedroom.

Bernadette: Gosh, Amy. I'm sensing a little hostility. Is it maybe because like Sheldon's work, your sex life is also theoretical?

Bernadette: (Shouting from the bathroom) How many times do I have to tell you to replace the toilet paper when it's empty?
Howard: I'm in the middle of something.
Bernadette: So am I!

Marissa: It's a little weird for us, too. I mean, instead of our baby looking like Zack, it's gonna look like Leonard.
Zack: Or Penny if it's a girl.
Penny: No, no, it's not gonna look- Sure.

Marissa: And, well, we're really hoping for a son. So just, like, keep that in mind when you're in there.
Zack: Yeah, just think, "Little boys, little boys."
Penny: Still just totally not weird.

Raj: Uh, if you still want to go, you can go to India and help my dad eat all the nonrefundable sushi.
Howard: Indian sushi? I need a change of underwear just thinking about that.
