Leonard: Okay. Now, what I'm hearing is that you feel that I sometimes take too long to express myself, and you wish I'd be more succinct.
Penny: You're only hearing that because I cannot roll my eyes any louder.

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

Penny: I mean, who even reads Scientific American?
Leonard: It's kind of a big deal.
Penny: If it's such a big deal, how come the biggest celebrity they could get for the cover is a molecule?

Howard: I'm not signing a prenup.
Penny: All right, Howard Wolowitz, listen up! You sign anything she puts in front of you, because you are the luckiest man alive. If you let her go, there is no way you can find anyone else. Speaking on behalf of all women, it is not going to happen, we had a meeting.

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.

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.

Raj: Come on, a medium-sized asteroid is still an interesting discovery.
Sheldon: I suppose it could end up on a collision course with Earth and destroy life as we know it.
Raj: You dream different than me.
