Sheldon: So tell us in your own words about that magical moment when Fun with Flags was born.
Leonard: I honestly don't remember.
Sheldon: Sure you do. I was telling you both the story about how Haiti and Lichtenstein discovered they had the same flag. It was at the Summer Olympics of 1936, and two plucky nations-
Penny: Oh, wait. I remember.
Sheldon: Oh, and do you remember what you said?
Penny: Yes. "Please find someone who cares."
*cut back to Sheldon and Amy in the "studio"*
Sheldon: And that's exactly what I did. I found a lot of someones.
Amy: Almost 200. Many of them on purpose.

Amy: Sheldon, you're sick, go back to bed.
Sheldon: (stuffy) I am fine. Here, eat your toast. (sneezes on the toast) Sorry.
Amy: It's okay, now I don't need butter.

Amy: "Revised ground rule number two: There are definitely stupid questions. And those who ask them can be told so right to their stupid face."
Sheldon: I love that one.
Amy: Thanks, babe.

Sheldon: Can you stop breathing so loud? I can hear your nose whistling.
Amy: I can hear your face talking, so we're even.

Sheldon: What if she's correct? Doesn't that say something troubling about us?
Amy: I don't know. I just think you're the kind of person who likes a contingency plan.
Sheldon: That is true. Did you know I figured out in which order I would eat all my friends in the event of an apocalypse?
Amy: You need to stop hanging out with your brain so much. It's not a good influence.

Sheldon: Before we eat, I have a little "welcome to the building" gift for Raj.
Penny: Wait, is anything gonna jump out-
Amy: No. I already asked.

Amy: You ready to go?
Sheldon: All set.
Amy: What's that?
Sheldon: A housewarming gift for Raj.
Amy: Well, a bunch of fake snakes better not spring out of it, 'cause that was a lousy anniversary present.

Amy: There are a lot of memories wrapped up in that room. For me, too. The first time you told me you loved me was in that room.
Sheldon: Wrong. We were standing outside my room in the hallway.
Amy: And there is the love of which I speak.

Amy: Don't listen to them. What's weird is that Penny almost got a science fact right.

Sheldon: I know our apartment's small, but I think we can make room.
Amy: No, Sheldon. We are not getting a life-size Spider-Man statue.

Penny: It's not that I want to go, I just think it'll make Leonard happy. And if I have to watch him squeeze into an Ewok costume, so be it.
Amy: Look at you, going to Comic-Con, talking about Ewoks. I really have become the cool one around here.

Amy: Hey, Sheldon, I found a great restaurant for date night.
Sheldon: Kind of busy right now.
Amy: Oh, an Euler's Disk! Fun!
Howard: Yeah, we're seeing if Raj can hold his breath longer than it.
Amy: Oh. Immature.

Amy: Hey, there's another dance club nearby. I mean, I don't know how you feel about Latin music, but according to their "horas of operacion", they're open.
Penny: Maybe we should just call it a night.
Amy: You sure? They're open till dos.

Amy: Did you hear anything back from the Caltech preschool?
Bernadette: Not yet, but we're gonna apply to a bunch of others just to keep our options open.
Penny: Okay, stop that! No more preschool talk. Tonight is about having fun.
Amy: Nothing says fun like being scolded.

Sheldon: On the first day, I get to drive a steam engine. Oh, and the second day, a diesel engine. Oh, and if I volunteer to do track maintenance and paperwork, they'll let me stay as long as I want. So you might want to pack enough clothes for the rest of our lives.
Amy: Can I pee now?
