Amy: I'm tracking a subject's brain activity in real time as we introduce olfactory stimuli.
Colin: I'm smelling baby powder.
Amy: That's just my husband.

Amy: Dr. Park, may I help you?
Dr. Park: Actually, yes, do you have any better notes on this project? I'm having a hard time reading your handwriting.
Amy: Oh, uh, allow me to rephrase that. What the hell are you doing in my lab?

Amy: Oh. You got an e-mail from someone named Tam.
Sheldon: Tam? What does he want?
Amy: Uh, looks like he's coming to give his son a tour of Caltech. He's hoping you guys can meet up.
Sheldon: (scoffs) He would like that, wouldn't he?
Amy: Well, that is the gist of the e-mail.

Sheldon: Anyway, Tam stayed with her in Texas, and I had to move out here all by myself.
Amy: That must've been scary.
Sheldon: It was. I was lonely, and I thought I'd never make a friend again. And for a long time, I didn't.
Amy: But then you did. And great friends. If you think about it, if Tam had moved out here with you, who knows what your life would've been like.

Amy: Just tell me what happened.
Sheldon: Leonard talked to Tam behind my back and took his side. And after what he did to me. Can you believe it?
Amy: No. I'm-I'm shocked and outraged. Now, tell me why I'm shocked and outraged.

Amy: I tried to ask him about it, and he invoked section three, article five of the marriage contract: beeswax, none of your.

Amy: Hey, whatcha doing?
Sheldon: Improving our wedding photos.
Amy: Oh, that's nice. Wait, I'm still in them, right?

Amy: Who's Tam?
Sheldon: He was my best friend in the whole world growing up.
Amy: Really? Why have I never heard you mention him before?
Sheldon: Oh, of course I have. I'm sure I've mentioned him, like, five times this week.
Amy: I don't think you have.
Sheldon: Tam! Tam! Tam! Tam! Tam! There, it's only Thursday.
Amy: I didn't just drink the crazy milk, I bought the crazy cow.

Amy: What the hell, Penny?!
Penny: I'm gonna need more than that.
Amy: You're not having kids? How could you do this to me?
Penny: How is it any of your business?
Amy: Because your kids were supposed to be friends with my kids. Who's gonna be friends with them now?
Penny: They will find other friends.
Amy: Oh, sure, 'cause Sheldon's DNA plus my DNA equals a kid who knows how to make friends. Grow up!

Penny: Listen, when you have kids, I'm still gonna be there. I'm gonna be their fun Aunt Penny who gives them candy, and teaches them swear words and tells them stories about what a weirdo their mother is.
Amy: I guess I could live with that. What is gonna be hard is letting go of the dream of us breastfeeding each other's babies.
Penny: And it's gonna be hard to forget you said that.

Penny: This is between me and Leonard.
Amy: Screw Leonard! We were supposed to get pregnant together. We were gonna be barf buddies. We were supposed to massage each other's perineums with vitamin E.
Penny: I'm about to be your barf buddy right now.

Sheldon: But I think, by the end of the honeymoon, we really started to feel like a married couple.
Amy: But the good kind, like on TV, not like my parents.

Amy: Oh, and look at this. A locket. And that stone in front, I bet it's quartz.
Sheldon: This must be it. This must be the actual gift. Open it up. What's inside?
Amy: Nothing. It's empty.
Sheldon: Of course. Our life together is just starting, and they want us to fill it with our memories.
Amy: This might be the best wedding gift ever.
Sheldon: (gasps) They also left us a pair of sunglasses because our future's so bright!
Amy: They thought of everything!

Sheldon: We just need to think like them. (inhales, exhales) Okay. What gift can I get us to express how grateful we are to have us in their lives?
Amy: Way to make it simple.

Amy: Sheldon, look, I asked the barista if anyone left anything for us, and she said to look in this lost and found box.
Sheldon: But why would it be in the lost and found box?
Amy: Because we were lost, and then we found each other.
Sheldon: It makes perfect sense.
