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?

Howard: This isn't complicated. Do you love Amy?
Sheldon: Yes.
Raj: Do you like living with her?
Sheldon: Yes.
Leonard: Do you know what you need to do now?
Sheldon: Apparently, figure this out on my own 'cause you guys are no help at all.

Leonard: Just hiding some stuff in your closet, don't tell Penny.

Sheldon: Would you care for a brandy?
Amy: I don't think so.
Sheldon: Good choice. It's disgusting.

Issabella: You know, I have to say, based on the candy wrappers and the bags of junk food I see in this trash, I thought the person working here was ten years old.
Raj: Oh, please, show me a ten-year-old who knows to dip Tootsie Rolls in Nutella.

Amy: Well, Sheldon I see astrocytes. Our combined skin cells are now a primitive neural network.
Sheldon: I have such a profound sense of creation. I jus- It's like when I hatched Sea-Monkeys, except that this is from my DNA, so this is like Me-Monkeys.
Amy: These cells come from both of us.
Sheldon: Yeah, but Us-Monkeys doesn't pop. Oh, oh, oh, oh, wait! We-Monkeys. There you go.

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.

Issabella: Good night, Rajesh.
Raj: Okay, I'll leave. But just know, every time I come in here, I'll be thinking of you.

Sheldon: Hey, where are you going? Did you even look at my bottom?

Raj: We're in the telescope room! It'll be like dining under the stars. You see this, uh, double zero? When it says "01" that means it's twinkling. ... Sometimes it takes a while.

Raj: I tried to cook you a meal from your homeland.
Issabella: Oh, really? You made Cuban food?
Raj: That depends. Do they have Mexican food in Cuba?

Penny: Now, when he said "make a baby" is it possible he meant out of Legos?
Amy: No. He was explicit. Needlessly and freakishly explicit.

(Amy, Leonard and Penny reach the fourth floor and discover Sheldon has laid out rose petals leading to the door of Apartment 4B)
Amy: Aww, man!
Penny: Ooh! Sheldon gonna get some.
Leonard: Well, have fun with whatever nightmare's behind door number two.

Raj: So, um, what surprised you the most when you first came to America?
Issabella: Well, I suppose how much people care about Oprah's favorite things.
Raj: I thought that, too. But then I got my first waffle maker and never questioned her again.

Raj: Issabella! Issabella, wait, wait, let me explain.
Issabella: If you are embarrassed by what I do, why did you pursue me?
Raj: I'm sorry. Honestly, I didn't think your job would bother me, but I guess it did. And I hate myself for that. But there's a lot of things about me that would totally embarrass you.
Issabella: I doubt that.
Raj: Well, prepare to be mortified. I let my dog eat food out of my mouth, not because she likes it but because I do. Also, I know they're pretty, but I'm scared of butterflies.
