Penny: There's this doctor who refuses to see any sales reps. I've been trying to get in for months.
Leonard: Well, did you try wearing the shirt I said was inappropriate for work?
Penny: Well, the doctor's a woman, but yes, because you never know.

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.

Sheldon: Perhaps I should explain. While working with Koothrappali, we discovered an asteroid, and I named it after you.
Amy: Oh, Sheldon, thank you. That's so romantic. But what about Rajesh? He was okay with you choosing the name?
Sheldon: Well, it took a little negotiating, but I wore him down. Uh, we get the asteroid, and if you and I have children, they all have to be named Rajesh.
Amy: All of them?
Sheldon: Even the girls.
Amy: Okay, I think I know what to say now.

Leonard: You know what'd be nice? Name it after your girlfriends. Show them how much you care.
Raj: That is a great idea.
Sheldon: It's perfect. It appears romantic, but it's really just a rock in space that gets me out of Valentine's Day forever.
Raj: So, uh, what were you thinking? Combine their names?
Sheldon: I like it. Yeah, we'll take the "Am" from Amy and, uh, the "Y" from Emily.
Raj: That's just Amy.
Sheldon: Exactly. See how well we work together?

Howard: You know, once we get the house back to ourselves, we can be romantic in any room we want.
Bernadette: Great. I can finally show you where the laundry room is.
