Penny: I'll see if it's available.
Amy: You know, if that study's real, Leonard might come back smarter than you.
Sheldon: Are you trying to manipulate me?
Amy: Yes.
Sheldon: Well done, it worked, we're going.
Amy: Yay!

Bernadette: He's just trying to be supportive.
Howard: Just supportive. Not over-the-top in any way?
Bernadette: No.
Raj: Hello. (Raj walks in with a gigantic teddy bear)
Bernadette: You saw him carrying that?
Howard: Astronauts saw him carrying that.

Raj: Of course. I'll give you guys some space. Let me just get this out of your way. (Raj fumbles around trying to move the gigantic teddy bear. He knocks over various objects in Howard & Bernadette's living room)
Howard: You need some help?
Raj: No, I got it.
Bernadette: Raj, Raj, wait.
Raj: Please, Bernadette. Let me leave with my dignity. (Raj falls over the teddy bear as he tries to move it out the door)

Howard: Hey, where you been?
Bernadette: Uh, Raj took me to the baby doctor and then we swung by the grocery store.
Howard: Did you get graham crackers? I mean, are - uh, is the baby okay?

Howard: I didn't know you needed help running errands today.
Bernadette: I didn't, but Raj volunteered.
Howard: Really?
Bernadette: Yeah, ever since you told him I was pregnant, he's really been making a fuss over me.
Howard: Oh. Well, I guess that's kind of sweet.
Raj: Bernie, I just forwarded you a list of the top five lactation consultants in Los Angeles. I know my favourite, but I'd love to hear what you think.
Howard: And it just got weird.

Penny: Sheldon, what did you do?
Sheldon: Well, I'm not proud of it, but I jaywalked.
Leonard: Oh, no, it's like a horror movie. We're trapped in a cabin with a maniac!

Bernadette: (Hearing their baby's heartbeat) Wait, that's it.
Raj: Wow.
Bernadette: Isn't that the best?
Raj: You guys made a person.
Howard: We did.
Raj: And I like to think I helped.
Howard: You didn't.

Sheldon: It's nice to get back to nature. Why don't I do this more often? What a beautiful forest. Hello, little butterfly. What's your na -- Oh!
Leonard: What'cha doing?
Sheldon: I was enjoying some virtual reality, until you ruined it with your actual face.

Leonard: Why are you pretending to be outdoors? You hate it.
Sheldon: Oh, Amy showed me a compelling study that demonstrated the cognitive benefit of spending time in the wilderness.
Leonard: Buddy, I am ready to drive you into the wilderness any time you want and leave you there.

Sheldon: Well, make your jokes, but some of the participants who spent four days in the woods away from all technology reported a fifty percent gain in reasoning skills upon their return.
Penny: Okay, if that's true, why aren't there more genius squirrels?
Sheldon: (Hands Penny the virtual reality headset) You may need this more than I do.

Bernadette: Come on, Raj, give me a bag.
Raj: No, no, you're pregnant. The only thing you carry is our hope for a better tomorrow.

Penny: Hey. Amy's downstairs.
Leonard: Okay, one sec.
Penny: Uh, what, what you got goin' on here?
Leonard: I bought a baseball cap.
Penny: I can see that. What team did you get?
Leonard: Uh, Hufflepuff, from Harry Potter.
Penny: Well, we'll be in the woods.

Howard: What the hell are you watching?
Bernadette: Raj found all these childbirth videos online. This one is of a woman giving birth in a river.
Howard: Okay, that is the least Jewish thing I've ever seen in my life.

Sheldon: Well, cell service is down to one bar, so if anyone needs medical attention or to tell a stranger their political views are stupid, now's the time.
Amy: Have you ever been off the grid before?
Sheldon: Once. The battery ran out on my phone. I had to wait for my iPad to turn on.
Leonard: I was afraid he was gonna eat me.

Penny: Hey, let's light a fire.
Amy: Ooh, that sounds cozy.
Leonard: I don't think I've lit a real fire before.
Sheldon: Ah, it's basic thermodynamics. I'm sure we can figure that out.
Leonard: I could stack the logs conically to facilitate airflow.
Sheldon: That would maximize oxygen for optimal combustion.
Leonard: Right. So all we need is to...
Penny: Got it.
Leonard: A scientist made that.
