Bernadette: That's whose handwriting that is.
Raj: I've noticed she's been over here a lot lately.
Howard: You know how you noticed that? Because you're over here a lot lately.

Leonard: You can't pick her up. It'll make me look like a bad son.
Sheldon: I imagine that's one of the things we'll talk about on the ride. That and Amy's recent reluctance to use turn signals.
Amy: We were in a parking garage.

Amy: I'm sure she's not mad at you.
Sheldon: Well, then why would she rather spend the day with Leonard?
Amy: Because he's her son?
Sheldon: Amy, I just feel like we're going in circles.

Sheldon: Oh, maybe I should pick her up.
Amy: You don't drive.
Sheldon: That's what makes you and me a great team. Go get your keys.

Beverly Hofstadter: Really? A photon entanglement team.
Leonard: Yeah, I'm actually the colead.
Penny: Yeah, if you like photons and how they get entangled, he's your co-guy.

Raj: Well, we got into this because we both wanted to get married, and honestly, we've been dragging our feet, and I think this is the push that we need.
Bernadette: Wait, so you're gonna ask her to marry you?
Raj: Why not? We like each other, plus, we both want to start a family. Hey, I can work from anywhere, I'm an astronomer. They have stars in London, and I'm not just talking about Dame Judi Dench.
Howard: No one thought you were.
Bernadette: I thought he was.

Penny: Come on, she gave birth to you.
Leonard: Fine, I'll pick her up.
Penny: Good, I'll go with you.
Sheldon: I call back seat.
Amy: Oh, I don't want to be the only one who doesn't go. I'll just sit here afraid that you're all talking about me.
Penny: We're not gonna talk about you.
Amy: Well, that's my other fear.

Stuart: Ready?
Denise: You sure I didn't need to see Paddington 1?
Stuart: He's a bear, he talks, no one knows why. You're all caught up.

Howard: Doesn't she have her own place? Why don't you guys hang out there?
Stuart: Oh, she has a roommate, and he's kind of creepy. A-And that's coming from me.

Howard: So she's coming over again, huh?
Stuart: Yeah, we're gonna do a movie night.
Howard: It's my house. Don't you think you should ask me?
Stuart: You're right, I'm sorry. Howard, would you like to come to movie night?

Beverly Hofstadter: Have you calmed down?
Leonard: No, I'm not calm. You really hurt me.
Beverly Hofstadter: That wasn't my intention.
Leonard: It doesn't matter what you intended. What matters is the way you made me feel. Actually, the way y-you've always made me feel.
Beverly Hofstadter: I see, so you're here to tell me all the ways that I failed you as a mother.
Leonard: Yeah. And get comfortable, 'cause i-it's a long list. [exhales]
Beverly Hofstadter: Is it happening soon?
Leonard: You know what? It doesn't matter. Doesn't matter, you're never gonna change. If I want you to accept me for me, then I guess I'm gonna have to accept you for you. So I forgive you.
Beverly Hofstadter: I didn't ask you to forgive me.
Leonard: Too bad. I forgive you anyway. And I forgive myself for taking so long to do it. Oh, my God, that feels so good.
Beverly Hofstadter: I must admit, it it does feel good.
Leonard: What does?
Beverly Hofstadter: You forgiving me. It means a lot. Thank you.

Denise: Hey, guys.
Raj: Hey.
Howard: Hey.
Denise: I'm sorry, I didn't know you had company.
Raj: It's all right, neither did they.

Leonard: I can't believe this.
Beverly Hofstadter: What? You seem angry.
Leonard: Of course I'm angry!
Beverly Hofstadter: Well, so would you say that you're somewhat angry, very angry or extremely angry? Never mind. I can see it in your face, dear.

Sheldon: I'm looking over my text correspondence with Beverly and I don't see anything that would have given her offense. Nothing's ambiguous, I spell everything out. Including "laugh out loud" and "what's the fracas?"

Bernadette: She has slept over every night this week.
Raj: Uh, no, no, she wasn't here Wednesday night.
Howard: Yes, she was. You didn't notice because you were in the hot tub in the backyard eating Oreos.
Raj: That reminds me. [gets up, goes to the shopping list and writes:] Oreos.
