Raj: Sheldon, what did Amy have that attracted you?
Sheldon: Oh, so many things: her mind, her kindness, and especially her body.
Raj: Really!
Amy: Relax. We're the same blood type; he know he could harvest an organ.

[first lines]

Sheldon: All right, we're about to go live. Everyone on their A game. [claps] Good energy... [flatly, to camera]
Sheldon: Hello. I'm Dr, Sheldon Cooper.
Amy: And I'm Dr. Amy Farrah-Fowler.
Sheldon: And welcome to a special retrospective, where we will take a look back at the history of Fun with Flags on an episode we're calling Sheldon Cooper, Amy Farrah Fowler: Fun with Flags: Behind the Flags, a Retrospective.

Raj: I feel bad for Bert.
Sheldon: So he's using his money to attract a mate. Is that any different than me using my intelligence to attract Amy, or Leonard using his power of grovelling to get Penny?
Leonard: Totally different. Bert's money might run out, but I can beg until the end of time.
Penny: All that, *and* he's shorter than me.

[last lines]

Sheldon: Hello. I'm Dr, Sheldon Cooper.
Amy: And I'm Dr. Amy Farrah-Fowler.
Sheldon: Based on the glowing reception of our recent Behind the Flags Retrospective we thought you might like to see how it all came together
Amy: So welcome to tonight's episode: Sheldon Cooper, Amy Farrah Fowler: Fun with Flags: Behind the Behind the Flags, a Retrospective Retrospective.
Sheldon: Oh, we already have our first call!
Amy: Oh. Hello, you're on Fun with Flags.
Bert: The jet-ski worked. I got her back.

Bernadette: What if she likes these people more than us?
Howard: She already likes bubbles more than us.

Howard: How about after this we go to the exotic bird show?
Stuart: Not a good idea. My hair is prime nest building material.

Howard: What are you making?
Stuart: Chicken. Birds mess with my hair, I come back hard.

Sheldon: [after Bert introduces Rebecca] She's younger and far more attractive than he is. [to Leonard and Penny] They're copying you two.

Sheldon: Bert, Rebecca, I'd like to apologize for my insensitive comment earlier.
Rebecca: Don't worry about it. It's fine.
Sheldon: See, it was fine. I didn't need a time out.
Amy: It wasn't a time out. Let's get some food.
Sheldon: You made me sit on the stairs and think about what I did...
Amy: [Nudges Sheldon] I said get your food!

Howard What are you doing here?
Stuart: Can't a guy hang out at a college he doesn't go to and stare at a baby that isn't his?

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

Leonard: Don't you have a friend you can set him up with?
Penny: Hey, I already set up Howard and Bernadette. It's your turn to ruin some poor girl's life.

Rebecca: Where's your bathroom?
Leonard: Just down there. [Rebecca leaves]
Bert: She's so perfect, sometimes I think she isn't real. And then she goes to the bathroom, and I know she is.
Penny: Aww, that's so weird.

Raj: I'd love a personal trainer. I haven't seen my abs since they opened a Shake Shack on my drive home.
Rebecca: I can give you some free sessions.
Penny: Oh, is that offer for everybody?
Leonard: Nice try. I'm not going.
