Sheldon Cooper: I'm trying this new technique where I imagine how I would feel in someone else's position.
Amy Farrah Fowler: Y-You mean empathy?
Sheldon Cooper: Oh, I thought I came up with it.
Amy Farrah Fowler: Well, regardless, I-I appreciate the effort.
Sheldon Cooper: Thank you. It's really hard.
Sheldon Cooper: I also have a pretty cute picture to share.
Howard Wolowitz: What is that?
Sheldon Cooper: An equation. Isn't it perfect? Sometimes I just stare at it, and I think "I can't believe that came out of me."
Sheldon Cooper: That is a list of all the different types of natural disasters.
Penny Hofstadter: “Fire-quake”?
Sheldon Cooper: I made that one up. Which I shouldn't have, because now I'm scared of it.
Leonard Hofstadter: Amy and I were talking about old science fair projects, and how fun it would be to recreate them.
Amy Farrah Fowler: We're making hot ice.
Leonard Hofstadter: Mm-hmm. It's pretty cool.
Amy Farrah Fowler: Nice one. (Amy and Leonard high five)
Amy Farrah Fowler: I need to tell you something about Howard, but you can't tell him that I told you.
Rajesh Koothrappali: Nope. Don't want to hear it. Do not like to engage in gossip.
Amy Farrah Fowler: Okay. I respect your integrity.
Rajesh Koothrappali: Is it about his special underwear? Because I already know. And that's all I'll say. Fine, it has a charcoal filter in it.
Leonard Hofstadter: I'm starting a book.
Sheldon Cooper: That would be big news from Penny, but you've read a book before.
Penny Hofstadter: He means he's writing a book.
Leonard Hofstadter: I do. It's something I've been thinking about for a long time.
Penny Hofstadter: Yeah. It's about a brilliant physicist who solves crimes using science.
Sheldon Cooper: Oh, Leonard...
Leonard Hofstadter: It's not about you!
Sheldon Cooper: He probably has to say that for legal reasons.
Leonard Hofstadter: Isn't Halley's birthday the same as Amy's?
Howard Wolowitz: Yeah, but we're not doing anything big 'cause she's one, Bernadette's on bed rest, and I'm lazy.
Sheldon Cooper: You know, we did get dressed up and come all the way to City Hall.
Amy Farrah Fowler: What are you thinking?
Sheldon Cooper: I have always wanted a permit to dispose of hazardous waste.
Amy Farrah Fowler: Let's do it.
Sheldon Cooper: Amy, I never thought I'd want to marry anyone. So the fact that I found you is astonishing. It's-it's like finding dark matter, except they're looking for dark matter. I wasn't even looking for you. S-So you're even better than dark matter. Plus, plus, you interact with light, so I can see you. And, also, you don't account for the missing mass in the universe. But when you make a discovery like this, you don't just take it down to City Hall... you tell the whole world. And so I'll say it in Latin or Klingon or-or smoke signals, if-if that's not cultural appropriation.
Amy Farrah Fowler: It is.
Sheldon Cooper: Okay, so not smoke signals. But I want to do this right.
