Bernadette: I brought sparkling cider.
Sheldon: Oh, the bubbles tickle my nose. I'll just open this now so it can get nice and flat before we drink it.

Bernadette: So what do you want to do tonight?
Sheldon: Oh, I have quite the evening planned. Our foetus-friendly festival of fun begins with an in-depth look at the world of model trains, and then we'll kick things up a notch and explore all the different ways that you can make toast.
Bernadette: There's more than one?
Sheldon: You've heard of French toast?
Bernadette: (upbeat) Yeah.
Sheldon: Cinnamon toast?
Bernadette: (upbeat) Yeah.
Sheldon: Melba toast?
Bernadette: (upbeat) Yeah.
Sheldon: You get where I'm going here?
Bernadette: (downbeat) Yeah.

Penny: Hey, are you still hanging out with Bernadette tonight?
Sheldon: Yes. And we're going to prove that we don't need alcohol to enjoy ourselves.
Penny: Oh, good for you.
Sheldon: Or caffeine, tobacco, sushi, soft cheese, processed meats and jacuzzis, which can all be harmful to an unborn baby.
Penny: No honey baked ham in a hot tub, got it.
Sheldon: Oh, no bubble baths either. They can increase the risk of a urinary tract infection.
Leonard: Okay, have fun.
Sheldon: Oh, and no swordfish, king mackerel, shark or tilefish, which are all high in mercury.
Leonard: We're leaving now!
Sheldon: Oh, and no contact with guinea pigs or hamsters or their droppings, uh, no-no cat litter boxes, no paint fumes.
Penny: Okay, we're leaving, love you, bye.
Sheldon: Boy, do I love restrictions.

Howard: Hey. Where is everybody?
Amy: Oh, we're the first ones here.
Howard: Oh, cool.
Amy: Yeah, cool.
Howard: You know, I don't remember the last time it was just you and me hanging out.
Amy: Oh, I do. It was three years ago.
Howard: Oh, yeah, and we said we should do it more often. And, and, and, and here we are.

Leonard: Hey.
Howard: Oh, good.
Amy: Oh, thank God.
Penny: You guys been here long?
Howard: No, two minutes.
Amy: But yes.

Amy: So, Sheldon and Bernadette are hanging out.
Howard: I know. What are they gonna talk about?
Amy: I don't know. I really don't know.

Amy: Hey, Penny, isn't that your old boyfriend Zack?
Penny: Oh, yeah.
Amy: Are you gonna say hi to him?
Penny: Um, I don't know.
Raj: Hey, while you decide, who was better in bed, big hot Zack or wheezy little Leonard? Neener-neener.

Penny: Hey, you ready to go?
Leonard: Hang on.
Penny: What are you doing?
Leonard: Oh, I found a scratch-and-sniff book about wine tasting. It teaches the different flavor notes to look for.
Penny: You actually smell the wine?
Leonard: I mostly just smell my nasal spray.
Penny: Are your sinuses acting up?
Leonard: Since my preschool got a bunny.

Raj: Hey, Claire.
Claire: Hey, what's up?
Raj: Hi, yeah. Um, I was wondering, if you're free Saturday night, all my friends are going to a wine tasting.
Claire: Sure, I guess. If you don't think meeting your friends is too big a step.
Raj: Why would it be too big a step?
Claire: I don't know. I just don't want things to get weird.
Raj: Nothing to worry about. People meet people all the time, and it isn't weird. I met Bon Jovi once, which you'd think might be weird. Turns out, total sweetheart.
Claire: Okay, but you and I have been keeping things casual. Uh, will you introduce me as your friend or as your girlfriend? What if I like them and they don't like me? What if they like me and I don't like them?
Raj: Boy, it wasn't this hard with Bon Jovi. I said you rock, he said "Thanks, man," and that was that.

Raj: Hey, you think it'd be okay if I brought Claire to the wine tasting?
Leonard: Sure. I'd like to meet her.
Raj: Oh, thats great. I've been wanting her to meet you guys, too, so this seems like the perfect opportunity.
Sheldon: Oh, but I won't be there.
Raj: Funny how that worked out.

Sheldon: I am going to record this for posterity.
Leonard: All right, here goes nothing.
Sheldon: Here goes nothing? This is the initial test of our prototype. Can we give it a little more gravitas?
Leonard: Fine. Preliminary trial of the infinite persistence gyroscopic navigational system, phase one commencing.
Sheldon: Eh, maybe it's your voice. I'm gonna see if I can get James Earl Jones to do it in post.

Raj: They know that we're not exclusive, and we just don't ask too many questions.
Sheldon: You know, it's like how I play Warlords of Ka'a with you and Elder Sign with Frank and Alicia.
Leonard: Who's Frank and Alicia?
Sheldon: You, you and I spend a lot of time together. Can there be a little mystery between us?

Howard: Well, we're out. Bernie can't drink 'cause she's pregnant. And she's pregnant because we had sex. And we had sex because, well, (points to his body) come on.

Bernadette: It's okay, you should go.
Howard: You sure?
Bernadette: Of course.
Penny: Yeah, give her a break from, well, come on.
Sheldon: Well, Bernadette, looks like Saturday night, it's you and me.
Bernadette: Me? How? Why?

Leonard: The difference is she's bringing life into the world, and you suck it out.
