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.

Leonard: Aren't you going with Sheldon?
Amy: No, I have no interest in model trains, stores that sell them, nor their heartbreaking clientele.

Amy: Should I go? I have been told sometimes I overstay my welcome.
Leonard: What? Who told you that?
Amy: Well, most recently my gynaecologist.

Bernadette: That's pretty big talk for a man with a closet full of magic tricks at his mother's house.

Amy: I need someone to accompany me to the wedding of Dr. Moranelli and Dr. Gustafson this Friday. They're kind of the Brad and Angelina of the primatology department.
Leonard: Wouldn't you rather bring Sheldon?
Amy: I would, but the last wedding we went to was a disaster. He behaved like a child the entire time.
Sheldon: Not my fault. You said there'd be other scientists there my age.

Penny: You're a brain scientist. Can you explain to me why a brilliant man likes playing with toy trains?
Amy: Not without cutting his head open, no.

Leonard: Who wants the last dumpling?
Penny: Ooh, me.
Sheldon: Penny, a moment. We just had Thai food. In that culture, the last morsel is called the krengjai piece, and it is reserved for the most important and valued member of the group.
Penny: Thank you all for this high honor.

Howard: All right, honey, if were gonna make the movie, we should go. (Raj stands up) This may be hard for you to hear, but when I say honey, I mean my fiance. (Raj whispers to Howard) Yeah, well, now it means her.
Bernadette: It's okay if he wants to come.
Howard: Fine. But next time, we get a sitter.

Sheldon: Wait. Uh, which is closer to the new train store in Monrovia, the movie theater or the Cheesecake Factory?
Howard: Neither of them are close.
Sheldon: Oh, well, then I guess it doesn't matter which one of you drives me.

Howard: First of all, they're not tricks, they're illusions. And, secondly, when we get married, they're all going up in the attic so you can have that closet for clothes.
Bernadette: Why would I keep clothes at your mother's house?
Howard: Well, don't think of it that way. Once we move in, it'll be our house.
Bernadette: Is she moving out?
Howard: Why would she move out? It's her house.

Bernadette: Hang on. You seriously think I'm going to live with your mother?
Sheldon: Howard, I think I can help here. Yes, Bernadette, that's exactly what he thinks.
Howard: Why not? It's a great house, plenty of room, and if we have kids, Mom's there to help. You know, when she tells the Three Little Pigs story, she actually has hair on her chinny-chin-chin.
Bernadette: I'm not gonna live with your mother. Not now, not ever.
Howard: Wow, someone obviously has some mommy issues.

Bernadette: Raj, take me home.
Howard: Don't listen to her. Go to the movie theater.
Bernadette: Take me home now.
Howard: Movie theater.
Raj: Mmmmmm.
Sheldon: Okay, everybody calm down. There is a simple solution here. Raj, take me to the train store, and then I don't care what you people do.

Amy: How was your shower?
Leonard: It was good, good. Just out of curiosity, what time do you usually go to bed?
Amy: Oh, I'm up all night. I'm like a possum.

Amy: Boy, you were not liked in high school, were you?
Leonard: Not really. Is that my yearbook?
Amy: Mm-hmm. Dear Leonard, you're really good at science. Maybe one day you'll come up with a cure for being a dork.
Leonard: Well, it wasn't spray-painting a lightning bolt on my briefcase, I can tell you that.

Sheldon: Well, you can add Jerry's Junction to the list of train stores Sheldon Cooper will never set foot in again.
Leonard: Rough night, Casey Jones?
Sheldon: You don't know the half of it. It was billed as a lively give-and-take on the merits of model train sizes. But it was actually a set-up to intimidate weak-minded spineless rubes into buying H-O starter sets.
Leonard: What's in the bag?
Sheldon: I don't want to talk about it. But it's not a spine,I'll tell you that.
