Penny: No, it's not that.
Bernadette: Then why?
Penny: Honestly, I don't know if I'm up to it. You know, the last project I managed was my high school yearbook.
Bernadette: And?
Penny: And that was the year we didn't have one. - And? And that was the year we didn't have one. Apparently, the printers won't make them without getting paid.
Bernadette: What happened to the money?
Penny: Uh, if I didn't know then, I'm not going to magically know now.

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.

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.

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: 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.

[Halley crying]
Howard: I'll go talk to her.
Bernadette: I don't know why she's suddenly so afraid of everything.
Howard: Honey, remember, she's my child, too.

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.

Sheldon: It's happening! [phone chimes] Unknown caller. It's got to be them.
Amy: Okay, put it on speaker.
Sheldon: Hello?
Amy: Hi.
Barry Kripke: Hello. This is Sweden calling. Is this Dr. Cooper and Dr. Fowler?
Sheldon: Yes.
Amy: Yeah.
Barry Kripke: Congratulations. It is my pleasure to inform you that you've won the Nobel Prize in being suckers!

Bernadette: My dad and I watched you win back-to-back championships.
Kareem Abdul-Jabbar: And I watched you sniff Joe's hair when he wasn't looking.

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.

Penny: So neither of them showed up for work today?
Leonard: No, I tried calling and no one picked up.
Penny: Look, I'm sure they're fine. They were probably up all night coming up with a new theory.
Leonard: I also texted to see if he wanted to go to the new Fantastic Beasts movie and he didn't respond.
Penny: All right, well, they're already dead. There's nothing we can do.

Sheldon: I suppose you're wondering why I put you through all this.
Leonard: You mean the last two minutes or the last 20 years?

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.
