(Howard and Raj sing while playing the keyboards and guitar, respectively)
Howard: Wondering how it all began?
Raj: You'll need a good attention span-
Howard: For information and entertainment-
Raj: That's equally effective-
Both: It's Fun with Flags - Behind the Flags: A Retrospective. Flags!

Amy: Now, I'm sure many of you are wondering how Fun with Flags began.
Sheldon: So let's hear from some people who were there at the very start. Howard, flashback sounds.
Amy: Could have played that on my harp.
Sheldon: Just roll the clip.

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.

Sheldon: Buda and Pest united to form Budapest. And that's why Budapest is the "Budabest".

Penny: I can't believe I'm saying this, but can we watch the news or something?

Alfred Hofstadter: You're a patient young lady.
Sheldon: Hey, hey! She's mine! Take a cold shower, grandpa!

Raj: I haven't had much success meeting people online.
Bert: I didn't either, until I revamped my profile.
Sheldon: What'd you do, delete your photo?
Amy: Go.
Sheldon: Fine.
Amy: And don't you slam that door.
Sheldon: Aw, man.

Amy: I'm sorry, Bert, but aren't you worried she's only with you for your money?
Bert: She better be. On our first date, I bought her an 80-inch flat-screen.
Sheldon: Your first date? Did you even measure her walls?

Guy #2: Is she just with you because you're rich?
Leonard: She makes more money than I do!

Amy: Sheldon, I've made more than enough accommodations for you. We're both grown adults. We've been far more intimate than this. If you don't want to snuggle, fine. But we're not building a pillow wall.
Sheldon: Okay, well, I am sorry. I'm just worried that my sensitivity to temperature could make this a rough night. And no offense, but your bottom radiates enough heat, I'm surprised there aren't iguanas lying on it.

Raj: Hey, sorry if last night was awkward.
Bert: Actually, it got me thinking that I shouldn't flaunt my money to find love. I might break up with Rebecca.
Leonard: Wow, that's a big step.
Raj: I think it shows a lot of character.
Bert: I'm gonna hold out and see if I can find a hot young blonde who likes me for me.
Sheldon: (laughs) That's a good one. Okay, now, Leonard, you tell a joke.

Leonard: Wow! An appearance by George Lucas's ... dermatologist. Oh, I want that autograph.
Penny: Oh, yeah.

Penny: Do you think living with Amy has somehow stirred up Sheldon's sexual appetite?
Bernadette: (grimacing with disgust) Ugh. How can you think that? Why would you even put those words together?

Penny: So, did you tell him about Princeton yet?
Amy: No, I'm waiting till he's in a good mood.
Penny: Oh, sweetie, you might not live that long.

Amy: Well, clearly mental tasks are not enough. Maybe you need to challenge your motor skills.
Sheldon: For the last time, I am not having a tickle fight with you.
