Amy: So, you guys lived with Sheldon for a long time-
Leonard: Long time.
Penny: So very long.
Leonard: By the way, congratulations again on your engagement.
Penny: Yeah, you got a good one.

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.

Bernadette: One of the great things about being pregnant is drinking cranberry juice out of a wineglass and watching people freak out.

Sheldon: I call this meeting of the Council of Sheldons to order. Let's take roll. Science Sheldon?
Science Sheldon: Present.
Sheldon: Texas Sheldon?
Texas Sheldon: Howdy.
Sheldon: Fanboy Sheldon?
Fanboy Sheldon: Greetings.
Sheldon: Germaphobe Sheldon?
Germaphobe Sheldon: Say it, don't spray it.
Humorous Sheldon: Where's Jock Sheldon?
Sheldon: Not the time, Humorous Sheldon!

Sheldon: Why can't there just be one week each month for famous people to die?
Amy: Well, they've already arranged to die in threes. What more do you want from them?
