Howard: Guys, so what do you think?
Leonard: Well, I don't know, we're pretty happy here.
Penny: Yeah. Plus, if we moved, we'd probably just get a loft downtown.
Leonard: Really? I always figured we'd get a place with a yard.
Penny: Oh, sure, yeah, that makes sense, so you could shoot hoops and mow the lawn?

Leonard: If I take it off, Sheldon wins.
Penny: Sweetie, every night you don't kill him in his sleep, he wins.

Raj: (To Amy) If you were having Sheldon's baby, would you really want him in the room?
Penny: Yeah, if he's in the room when they're making the baby, I'll give you $10.

Sheldon: Woman, you are playing with forces beyond your ken.
Penny: Yeah, well your Ken can kiss my Barbie.

Amy: Hey. Wait a minute, what about us? I mean, we're married now. Maybe we want to buy the house next door.
Sheldon: Well, Amy, we can't move. I'd have to change all the tags in my underwear.
Amy: You can buy new ones.
Sheldon: New house, new underwear. What am I, in the Witness Protection Program?

Sheldon: You're awfully quiet.
Leonard: Sorry.
Sheldon: No, I like it.
Leonard: Got a lot on my mind.
Sheldon: Would you like to talk about it?
Leonard: Not really.
Sheldon: Grape Nuts for breakfast, quiet car ride, things are really breaking my way today.

Amy: You're really letting your father pick out a wife?
Raj: Why not? Arranged marriages have been working for thousands of years. Anu and I come from similar backgrounds, our families get along and we each filled out questionnaires, so we know we're not wasting our time with someone who's not compatible.
Penny: Oh, that sounds so dry and clinical.
Sheldon: You lucky duck.
