Amy: From a neurobiological standpoint, Leonard, you may be alone because your psychological state is causing an actual pheromone-based stink of desperation.

Amy: I believe a misunderstanding may have occurred when I asked you to meet my mother.
Sheldon: No misunderstanding. I've learned what that request actually means, and I don't want to be joined to another object by an inclined plane wrapped helically around an axis.
Amy: In what way are you screwed?

Amy: I trust this clarification allows us to return to boy-slash-friend-slash-girl-slash-friend status.
Sheldon: Of course. Would you like to join me for Chinese food?
Amy: Sheldon, please, you're suffocating me.
Sheldon: My apologies. Good night, Amy.
Amy: Good night, Sheldon.

Sheldon: I have a confession. When I berated Leonard, it was a clever ruse to conceal the fact that I'm not working on anything.
Amy: Well, I think I speak for everyone when I say, "No!"

Penny: So what's all this?
Leonard: Well, Amy and I were talking about old science fair projects, and how fun it would be to recreate them.
Amy: We're making hot ice.
Leonard: It's pretty cool.
Amy: (chuckles) Nice one. (Amy and Leonard high five)

Leonard: I'm sorry, we don't have to do more experiments. Let's do something we can all enjoy.
Amy: Hey, uh, you want to watch that show you like where people want to buy a house and then they do?

Leonard: So, I think if we want to predict the height of the wave, we need to use elasticity theory and model the lattice as one continuous flexible piece.
Amy: This is fun.
Leonard: Mm-hmm.
Amy: Playing with Popsicle sticks, exploring ways to store kinetic energy. It's like preschool all over again.

Amy: I was gonna ask if being married felt any different.
Leonard: Oh, uh, not really. Sorry. That probably wasn't the answer you were looking for.
Amy: No, actually it is. I mean, Sheldon and I are in a really great place right now, and I just, I don't want anything to mess that up.
Leonard: Mm-hmm. You do remember you're here because he kicked you out of your apartment?
Amy: Yes. His work is important to him. It's one of the things I find the sexiest about him. Well, that and-
Leonard: Aah! [setting off the lattice]
Amy: - his butt.
Leonard: Ugh.

Leonard: Stop that!
Amy: Hey, your mad look and Sheldon's constipated look are the same.

Sheldon: How could Wil ask Howard to be on his show and not me?
Amy: Well, he is an astronaut. And he didn't start an online petition to get Wil fired.
Sheldon: But why wouldn't Howard tell me?
Amy: Well, because he probably worried that you'd be a big baby about it.
Sheldon: All those answers make a lot of sense. Thank you, Amy. That helps.

Sheldon: You’re good friends with Penny, right?
Amy: Best friends, besties, BFFs, peas in a pod, sisters who would share traveling pants. Go on.

Penny: Pretty cool, huh? Probably would cost, like, two hundred bucks in a store.
Amy: I do appreciate a bargain. This entire ensemble once belonged to my dead grandmother.
Penny: You're kidding.
Amy: Everything except bra and panties. And they're a leopard-spotted secret I share with Victoria.

Howard: Hey, I just wish I could be there when you present it.
Amy: That's okay. It's more important that you spend time with Michael.
Howard: Who's Michael?
Amy: Uh, your son?
Howard: No, it's not. My son doesn't have a name yet.
Amy: (long silence) Okay, well, then, Bernadette's son.

Amy: I mean, Leonard and Penny are right there.
Sheldon: But he told me he checked on our membership just last week, and we were still 400th in line.
Amy: I'm sure there's an innocent explanation that won't ruin my day at all.

(The girls enter Stuart's comic book store)
Bernadette: Why are they staring?
Amy: Who cares? Just soak it in. Hello, boys.
