Leonard: If you like her so much you can have her, 'cause I-I'm done.
Sheldon: Oh, great. Catch the two of you later.
Amy: Sheldon, no.
Sheldon: Why?
Amy: Well, it's an emotionally complex issue. I don't have time to explain it right now.
Sheldon: Okay, but that excuse is running out of steam.

Leonard: I am so stupid. I-I actually thought my mom was genuinely proud of me. It turns out, she's just using me as research for her new book.
Sheldon: Oh, what a relief. I thought Beverly was mad at me. Thank you, Leonard. That is a weight off my shoulders.

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.

Beverly Hofstadter: Yeah, that's a fair point. I hadn't considered your influence. Perhaps tomorrow I could observe the two of you together?
Penny: Uh, "observe"? [laughs] What is going on?
Beverly Hofstadter: I'm just visiting with my son and doing research for my book on how various parenting strategies affected my children as adults.
Leonard: This has all been work to you? Hanging out with me and coming to my lab, I- I thought we were enjoying each other's company, but it was just research.
Beverly Hofstadter: I was enjoying it; you know I love research.

Leonard: It made me really happy. We haven't always had the easiest relationship. But, well, looking back, I guess you were just trying to push me to be the best version of myself.
Beverly Hofstadter: So you would say that my parenting strategies, although difficult at times, directly contributed to your current success?
Penny: Well, I may have had a little something to do with it. I mean, how often do you wear your superhero underwear now?
Leonard: Only Fridays and my birthday.
Penny: Yeah, that was all me. That was me.

Penny: Still, it made him so happy showing you around his lab yesterday.
Beverly Hofstadter: Interesting. Would you say that that made him, uh, much happier than usual, somewhat happier than usual or as happy as usual?
Penny: Hmm, multiple choice. Um, I'm-a go with D: "that's a weird question."

Penny: Beverly, I have to say, it's so nice seeing the two of you get along.
Beverly Hofstadter: Oh, I've always gotten along with Leonard. Of all of my children, he's the most docile.
Leonard: She wrote that in a birthday card once. I keep it in my nightstand.

Raj: I'm flying out tomorrow. I'm gonna surprise her with a ring.
Bernadette: You already have a ring?
Raj: Well, it's the same one as before.
Howard: I thought you gave it to her the first time you got engaged?
Raj: I did, but I took it back.
Howard: So, you're an Indian giver?
Bernadette: Howie.
Howard: What? If he's gonna move to England, I need to get all these out now.

Bernadette: So she's staying in London? What does that mean for your relationship?
Raj: It's great.
Howard: I can see why she would say that, but why do you?

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.

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.

Howard: It just feels like Denise is basically living with us. You know, maybe you can spend half the time at her place.
Stuart: Hey, when I moved in, you and Bernadette said it was okay if I brought girls over.
Howard: [laughs] Oh. We were making fun of you.

Leonard: And this is a high-pulse laser with a BBO crystal. It's pretty cool. It emits photons in discrete bursts.
Beverly Hofstadter: Huh. Very impressive.
Leonard: But?
Beverly Hofstadter: But what, dear?
Leonard: Oh, I don't know. It's just, usually there's a "but" followed by something that makes me feel bad.

Denise: All right, I got to head out to my drawing class.
Stuart: Fruit or naked dudes? Actually, it doesn't matter, I'm jealous of both.

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.
