Sheldon: I brought Amy here to show her some of the work I'm doing.
Amy: It's very impressive, for theoretical work.
Sheldon: Do I detect a hint of condescension?
Amy: I'm sorry, was I being too subtle? I meant compared to the real-world applications of neurobiology, theoretical physics is - what's the word I'm looking for? Hmm, cute.
Sheldon: Are you suggesting the work of a neurobiologist like Babinski could ever rise to the significance of a physicist like Clerk Maxwell or Dirac?
Amy: I'm stating it outright. Babinski eats Dirac for breakfast and defecates Clerk Maxwell.

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

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.

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

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.

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.

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.

Sheldon: If we did continue living together, would it be here?
Amy: I don't know. It could be.
Sheldon: Of course there's there's always your apartment.
Amy: Sure, sure, we could live in my apartment.
Sheldon: I hate your apartment.
Amy: Sorry, you brought it up?

Amy: So, enough about us, how are things going with you?
Bernadette: Great, the doctor said the baby's head is facing down now.
Amy: Good, you know, in case the exit isn't clearly marked.

Theodore: Excuse me. It's none of my business, but it sounds like a lot of this anger is coming from love.
Leonard: Yeah, thanks, but nobody asked you.
Theodore: Well, I'm just gonna keep on talking. Seems like, with Sheldon moving out, you're in a new phase of your lives and it's easier to fight than to face the feelings that you have for one another.
Amy: I think he might be right. Also, who is that?

Amy: (hiding behind the door in her Harry Potter costume) Hello Is this about the baby?
Raj: No. People just keep kicking me out everywhere I go.
Amy: Good. Then you're used to this. (closes the door on Raj)

Leonard: How did you get him in the car?
Amy: I rented one of those carts, pushed him toward the open door and just let inertia take care of the rest.

Penny: So tell me, how did Sheldon look with an earring?
Amy: Like the pirate who helps the other pirates connect to the Internet.

Amy: Penny, is it weird that we're having girls' night here, but you don't live here anymore, so it's basically my girls' night?
Penny: I hadn't really thought about it.
Amy: But now you're thinking about it and it bothers you? I get that.
