Amy: Here they go fighting again. You'd never hear her talk that way to sauvignon blanc.

Penny: Well, a relationship is more complicated than a french fry.
Sheldon: Not according to the work of Berscheid, Snyder & Omoto.
Penny: Oh, what did those rascals do now?

Bernadette: You're embarrassing me.
Amy: Oh, don't be embarrassed. I'll show you the divot in my spine.
Bernadette: What?
Amy: No, it's okay. I was born with it. If you put a double A battery in there, it makes my leg kick.

Penny: You know, maybe if fashion magazines had female scientists in them, I would have become a theoretical physicist. Stop smirking at each other!

Bernadette: Fine, what is it?
Howard: It's to help re-open the Comic Book Store.
Bernadette: Nope.

Amy: I didn't kill anything. You did, talking about your stupid TV show.
Sheldon: Excuse me. Starting to watch a television show that might run for years isn't a decision to take lightly. I'm wrestling with a big commitment issue here.
Amy: Really? That's the commitment issue you're wrestling with?

Sheldon: Can't talk. Spit ball. Probably gonna die.

Raj: I love how they put a waterfall at centerfield. It really ties the whole stadium together.
Penny: Look at you talking sports.

Raj: Well, I would never leave you off my list. And not just because without you we're playing fast and loose with the word "list".

Penny: I don't know what Emily's so upset about anyway. Even if I had slept with him, so what? Everyone has a past.
Amy: Ahem.
Penny: Almost everyone has a past.

Penny: If I do well in sales, I could end up making a lot more money than you.
Leonard: Not a problem. I grew up with a mother who emasculated my father financially and in every other aspect of his life, so really it's what I think love looks like.

Dr. Lorvis: I was hoping to impress her by tracking her down on the Internet and then showing up announced at her door.
Sheldon: Making the extra effort. Good for you.

Dr. Lorvis: I met her at my office. She winked at me. And I came hoping to initiate a romantic relationship.
Leonard: I'm pretty sure she didn't wink at you.
Dr. Lorvis: Oh, she did. Seductively, like this. And then she touched my arm for two Mississippis.

Bernadette: Please don't go. Up until my vicious attack, you were the one in the wrong.

Howard: How'd you get that?
Dr. Lorvis: Easy. Gene Rodenberry needed a vasectomy.
Sheldon: You've snipped Gene Rodenberry's vas deferens?
Dr. Lorvis: Yes.
Howard: Wow, you really went where no man has gone before.
