Bernadette: Bad news, Howie. I'm gonna be stuck at work for a while. Oh, that's terrible.
Hang in there. I'll be home as soon as I can. (sighs) He deserves better.

Bernadette: I had a plan. I kept leaving Dove bar wrappers around to explain any weight gain.
Amy: Where did you get empty Dove bar wrappers?
Bernadette: From all the Dove bars I ate! I'm pregnant! Try to keep up!

Stuart: Oh, so she's good enough for Howard but not for me?
Howard: Yeah.
Bernadette: Yeah. Go have weird relationships with your own mother and cousin. This is his turf.

Leonard: You don't go into science for the money.
Bernadette: Speak for yourself. Last month my company both invented and cured restless eye syndrome. Ka-ching, ya blinky chumps!

Penny: Where does Sheldon think you are?
Amy: Oh, Sheldon's kind of like a dog, he doesn't really think about me when I'm gone, but he's so happy when I show up.

Sheldon: All right, I've kept you in suspense long enough. "Dutch" is a bastardization of the word "Deutsch," meaning German.
Penny: What's German for "annoying"?
Sheldon: Nervig. Why do you ask?

Sheldon: This reminds me of a traditional Amish barn raising. With everyone pitching in.
Howard: How exactly are you pitching in?
Sheldon: I don't hear anyone else giving facts about traditional Amish barn raising.
Leonard: The rest of us are pitching in with hammers and nails.
Sheldon: Well, facts are my nails, and my voice is the hammer which pounds them through the wood of your skull.
Penny: Well, that is how it feels.
