Amy: It's just so much easier to give him what he wants.
Leonard: Oh, true, but think of how much you've accomplished. Who got him to stop Purelling his pocket change?
Amy: Me.
Leonard: And who got him to put things other than gloves in the glove compartment?
Amy: Me. It was mittens.
Leonard: Mm. And who got him to try a turkey dog?
Amy: That was actually Koothrappali, but I did let him spit it out in my hand.

Amy: What would a theoretical physicist understand about an experiment anyway? I mean, you wouldn't know a confounding variable if two of them hit you in the face at the same time! And you don't even get that joke, 'cause you don't even work with confounding variables!

Amy: Sheldon, maybe living together is a bad idea.
Sheldon: But what kind of scientists would we be, drawing a conclusion after only 12 hours of data?
Amy: The kind who almost put a pillow over your face last night.

Amy: Sheldon, will you please just pick a side?
Sheldon: Fine. Okay, now, on this side, I am closer to the exit in case of emergency.
Amy: Great. That's your side.
Sheldon: No, but I'm also closer to the entrance in case of attack.
Amy: Okay, I'll take that side.
Sheldon: Ah, then again, what are the odds of someone attacking me?
Amy: Rising rapidly.

Amy: Well, if you're nervous about the sleeping arrangements, maybe we should talk about it.
Sheldon: Okay. Talk.
Amy: Well, I imagine one of your concerns might be coital expectations.
Sheldon: Wow, no foreplay or anything, just right to it.
Amy: Look, I know this experiment is a big step outside of your comfort zone. So why don't we take being physical off the table and maybe later on, once we're more settled in, we can revisit it.
Sheldon: You're really okay with that?
Amy: I've never lived with someone, either. This is a lot for me, too.

Bert: And when Amy started using a solution of chromic acid and white vinegar to clean all her lab equipment, all of a sudden, everybody was doing it.
Penny: You trend setter!
Amy: Just the right idea at the right time.

Penny: Oh, I'll go. I like a party.
Amy: Well, to be honest, it's not like a "party" party. It's more like a gathering where scientists of different disciplines get together to share their work and keep current on what's going on in other fields. I don't know why I called it a party, sorry.

Bernadette: I've worked so hard to get where I am, and I don't want to get sent back to square one because I'm pregnant.
Amy: I understand how you feel.
Bernadette: Thank you.
Amy: I wish there were some way I could make it better.
Bernadette: Well, you brought me French fries. That's a start.
Amy: Uh, actually, I got you apple slices 'cause you're pregnant.

Amy: I am really regretting that I got you a Happy Meal.

Penny: Oh God, I feel so bad, I just lied to her.
Amy: Oh, but you did it so well. That's amazing! It's like watching a sculptor, but your clay was lies.

Bernadette: I don't believe this.
Amy: What's wrong?
Bernadette: This guy from the office just congratulated me on being pregnant.
Amy: You did already know, right?

Amy: Sheldon, they haven't done anything wrong. I think it's nice they're hitting it off.
Sheldon: Well, that's still no reason to rush into anything. Look at us. We took things remarkably slow. You and I, we didn't even hold hands for two years.
Amy: It was a lot hotter than it sounds.

Amy: I gave you one job! Keep an eye on him. How hard is that?

Amy: I've been smacking that ketchup bottle for a long time. All she has to do is tip it over and point it at her fries.

Amy: It's so strange. Earlier today, I ended a sentence with a preposition, and you weren't there to correct my grammar.
