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.

Amy: Hi. Howard told me you were working late, so I brought dinner.
Bernadette: Oh, thanks. You know, I just wanted to get some work done without people congratulating me about the baby every five minutes.
Amy: I spent my day alone in the lab waiting for a rat to die of anthrax.
Bernadette: Did you come here to bring me dinner or to gloat?

Penny: Are you still upset about people finding out you're pregnant?
Bernadette: I'm furious.
Penny: Sure, sure. Uh, did you ever figure out who told?
Bernadette: No. I confronted Barbara Chen, but she claimed she didn't know what I was talking about.
Penny: Hmm. Well, I guess it's just gonna remain a mystery, you know, like whatever happened in that seminar after they dimmed the lights. (laughs)
Bernadette: It had to be Barbara. I've been trying to figure out a way to get back at her. Do you think using her work computer to Google "how to be a prostitute" is over the line?

Bernadette: I'm worried about Howard. Ever since that guy from the Air Force showed up, he's been a nervous wreck.
Penny: We work at a giant pharmaceutical company. Get him some anti-anxiety meds.
Bernadette: He won't take any pills that aren't chewable and shaped like a Flintstone.

Bernadette: Did you tell anyone?
Penny: No, you told me not to.
Bernadette: I bet it was Barbara Chen in retrovirus. She might have heard me throwing up one morning. Every since she got the hearing aid, she thinks she's so great.

Amy: Why don't you want anyone to know?
Bernadette: 'Cause I'm up for a major immunotherapy study, and if they find out I'm pregnant they might give it to someone else.
Penny: Would they really do that?
Bernadette: I know they would. They did it to Barbara Chen last year when I told everyone she was pregnant.

Bernadette: Anybody have anything snarky to say about that? Didn't think so.

Bernadette: Not just Leonard and Penny's love, but the love we have for them, as well as each other.
Sheldon: Speaking of love, STDs among the elderly are skyrocketing.

Bernadette: Love is patient, but it's not gonna put up with all the side chatter, so let's knock it off!
Howard: At least she's yelling at someone else for a change.
Bernadette: Howard!

Penny: I didn't know you could drink while you were breastfeeding.
Bernadette: Yeah, they say the yeast in beer helps with milk production.
Amy: I'm pretty sure that's a myth. Let me check.
Bernadette: Ruin it for me, and I'll break this glass over your head.

Penny: You want food?
Bernadette: Yeah, breastfeeding burns, like, 5,000 calories a day. (To Amy) Do not touch that phone!

Leonard: Anyway, I figured I can hang out with my friends and have fun too.
Bernadette: Well if your idea of fun is riding in a minivan to Target for diapers, things are about to get nuts.

Bernadette: Smells ripe in here. You can kinda feel it in your eyes.

Bernadette: If you don't know how to make lasagna, Google does.

Bernadette: Stuart, don't you drink my milk!
