Howard: All right, got his enemies list. Ooh, he updated the interface. You can search by first name, last name or length of grudge.
Raj: Is Tam on it?
Howard: Let's see. Yep. Right here. Tam Nguyen.
Leonard: Oh, great. What did he do?
Howard: Hold on. I have to agree to the terms of service. No, I'm not a robot. Okay.
"Which of these are plants?" And we're in.

Sheldon: How did you get down here?
Penny: The elevator. It's really fast.
Sheldon: I-I need to be alone right now. Don't try to follow me.
Penny: All right. You need a ride?
Sheldon: That'd be great. Thank you.

Raj: Wait, wait, so you don't know what their fight was about?
Georgie: I wish I could help you, boys. But, you know, Sheldon used to keep an enemies list when he was a kid.
Leonard: Oh, he still does.
Georgie: Really? I figured that went the same way as his bathroom schedule.
Howard: If you mean digitized, annotated and put online, it did.
Georgie: Maybe that'll tell you something. Hey, while you're looking at it, if I'm still on there for peeing in his shampoo bottle - Eh, you know what, just leave it.

Ms. Davis: Thank you both for coming. President Siebert asked that I be a part of this conversation to help us calmly discuss what went wrong and how we can better move forward. We are not here to point fingers, so, Dr. Cooper, please stop that.

Leonard: Next question. Uh, "how close are you with your family?"
Penny: Pretty close.
Leonard: I'm gonna say not too close, but I'm hoping to get farther.

Sheldon: It's so funny, we did all these experiments on them and they didn't even notice.
Amy: I know, I was worried it would be obvious, but it wasn't.

Dr. Koothrappali: Hello?
Raj: Hey, Dad.
Dr. Koothrappali: Rajesh. What a nice surprise, calling me on my birthday.
Raj: Yes. That's why I'm calling. And-and what better gift to give you than the gift of marrying an Indian woman, just like you've always wanted.
Dr. Koothrappali: My goodness, Rajesh, this is exciting news. Who is she?
Raj: You tell me.
Dr. Koothrappali: What?
Raj: I want you to arrange a marriage for me. I'm just so tired of being single, and I'm finally just I'm-I'm ready to settle down.
Dr. Koothrappali: I can't just call up some girl's dad and make her marry you. It's-it's not 2015 anymore.

Raj: I never thought I would see Sheldon enjoying himself around babies so much.
Amy: Yeah, how about that?
Raj: So he just happened to stumble upon a book about experimenting with them the same day we were hanging out with Howard's kids?
Amy: Yep, don't overthink it.

Amy: Okay, imagine you're looking in a mirror. The image you see looks just like you. That's called symmetrical.
Sheldon: Now imagine you have a billion mirrors, and each of them reflects one thing about you correctly and a billion things about you incorrectly. And imagine the set of incorrect things are floating in an abstract n-dimensional hyperspace. Now imagine there was never a mirror to begin with.

Leonard: I'm glad you guys made up.
Sheldon: Well, I realized my life turned out great, and it's silly to hold a grudge.
Tam: And I had no idea we were fighting, so it was easy.

Amy: I should've seen this coming.
Raj: Oh, stop. You're allowed to get a haircut.
Amy: I know. But I should've done it gradually. You know, like maybe 300 tiny haircuts over a ten-year period.

Leonard: Sheldon, that was really rude.
Sheldon: I'm sorry. Amy is the one constant I can count on, and now she's changing.
Leonard: It's just a haircut and some clothes.
Sheldon: No, it's the last straw! I can't take any more! [elevator bell dings]
Penny: Can you believe it? They finally fixed the elevator.

Amy: You're really letting your father pick out a wife?
Raj: Why not? Arranged marriages have been working for thousands of years. Anu and I come from similar backgrounds, our families get along and we each filled out questionnaires, so we know we're not wasting our time with someone who's not compatible.
Penny: Oh, that sounds so dry and clinical.
Sheldon: You lucky duck.

Howard: Enjoying your book?
Bernadette: So much.
Howard: Why do you keep poking at it?
Bernadette: Fine, I'm shopping on my phone.
Howard: You're the one who said you wanted to read more.
Bernadette: Yes, I also tell people I only feed the kids organic. It's just stuff you say.

Amy: You're up early.
Sheldon: Huh? Yes. I wanted to get a jump on planning a day of fun for you.
Amy: Oh, that's sweet. What are we doing?
Sheldon: Oh, no. Just you. I have other plans. Now, would you prefer to see The Grinch in 2-D or 3-D?
Amy: I don't want to see it at all.
Sheldon: Well, let's go 2-D. No sense in spending extra money.
