Howard: Should we do something about Nowitzki?
Leonard: Like what?
Raj: Well, she's single, so if somebody else asks her out and she says yes, then we know she's not into Sheldon.
Stuart: I'll do it.
Leonard: No offense, Stuart, but the woman's a doctor.
Stuart: So? Doctors like me. Whenever I see mine he calls in a bunch of other doctors to have a look.
Howard: She's not that kind of doctor.
Stuart: Oh. Well, her loss. I've been called a genuine medical oddity.

Stuart: Is it weird if we just stand here and watch her all day?
Howard: Probably.
Stuart: We should go.
Howard: Yeah.
Stuart: Or we could take her to the aquarium.
Howard: I'll get her, you grab her bag.
Stuart: Hang on, Halley, we're busting you out of there!

Howard: What are you doing here?
Stuart: Can't a guy hang out at a college he doesn't go to and stare at a baby that isn't his?

Howard: Look, if you're not ready to go back to work, we'll figure something out.
Bernadette: No, I'll be fine.
Stuart: It might be good for her. Howard's mother was around him all the time, and he's a world-class mama's boy.
Howard: (scoffs) I mean, wh-why would you say that?
Stuart: Go ahead, have a tantrum; that'll prove me wrong.

Howard: What are you making?
Stuart: Chicken. Birds mess with my hair, I come back hard.

Bernadette: It's not just the sloth. Polar bears nurse their cubs for almost eight months. The orangutan mother builds her baby a new home every night. And what do I do? I choose my career over my child!
Stuart: (To Howard) Told you we should have gone to Legoland.

Howard: How about after this we go see the exotic bird show?
Stuart: Not a good idea. My hair is a coveted nesting material.

Bernadette: When I go back to work, we're gonna leave her with these people. We don't know anything about them.
Howard: They're highly-trained educators with background checks. They're even required to be current on all vaccinations.
Stuart: You leave her with me, and I'm not any of those things.

Howard: You okay?
Bernadette: Of course, why?
Howard: Well, I don't know, you seem a little upset.
Bernadette: No, I'm fine.
Howard: You sure?
Stuart: Why don't you think she's fine? She sounds fine, she looks fine. If I saw her on the street I'd say, "Damn, that girl's fine!"

Howard: Speaking of which, for day care, it'll be easy for me to drop her off, unless you want to do it.
Bernadette: Hmm, guess it should be me.
Stuart: I can't do it; they have a picture of me on file now.

Bernadette: Yeah, I mean, with you and my parents, she's gonna be fine.
Stuart: Ah, of course she is.
Bernadette: And that day care is great.
Stuart: It is. I went to check it out, and they are very cautious about letting strange men with no kids peek in the windows.

Stuart: Oh, thanks again for letting me use your laptop last night.
Bernadette: No problem.
Stuart: Was just doing my taxes.
Bernadette: Okay.
Stuart: Actually, if I could if I could just check one more-
Bernadette: Already cleared the browser history.
Stuart: You're a good woman.

Stuart: Uh, other than burp you or give you a bottle, I don't know what to do right now.

Stuart: (coming into the living room) Halley's fine.
Bernadette: You know she's at my parents' house, right?
Stuart: And she's having the time of her life.

Raj: No, you see, I'm doing this so I can stop being spoiled and, you know, grow as a person.
Stuart: Good for you. This sandwich has six dollars worth of ham in it.
