Sheldon: That may be true, but Dr. Nowitzki's just a friend. In fact, I wouldn't have even noticed she's a woman if she hadn't worn that bathing suit that highlighted her bosom.

Penny: All right, then we agree. He's not making any moves, it's this Dr. Ramona chick.
Bernadette: Nowitzki. I Googled her, she's pretty cute.
Penny: Really? All I got from Leonard was the Toblerone bar had nuts.

Penny: Okay, let's try this. Think of yourself as one of those limited edition toys people like to collect.
Sheldon: I already do.

Penny: All right, this is making me crazy. Somebody's got to go over there.
Leonard: You got feet and legs, you do it.

Ramona Nowitzki: No, my work doesn't leave me a lot of time for relationships.
Raj: I think you made that very clear.

Penny: Will you go with me?
Bernadette: To do what? Shake a can of nickels at them?

Leonard: You actually got in a pool?
Sheldon: I was scared, but I told myself it's just a big bathtub. Then I got scared again 'cause there are all these strangers in my bathtub.

Sheldon: She's always been a huge fan of my work, and now she's doing research at Caltech.
Amy: Huge fan, you say?
Sheldon: Yes. I think you'd like her. She's extremely intelligent, just like you. Unlike you, she's tall, blonde and used to be an Olympic swimmer.

Amy: It's so strange. Earlier today, I ended a sentence with a preposition, and you weren't there to correct my grammar.

Sheldon: Hey, I hate to break up the party, but Amy says I'm tired and have to go to bed.

Sheldon: Gentlemen, you may remember Dr. Nowitzki. She's back at Caltech for her postdoc.
Leonard: Hello.
Ramona Nowitzki: Hello.
Raj: Hi. Oh, let me bring a chair for you.
Sheldon: Oh, thanks. Dr. Nowitzki's going to tell me about the work she did at CERN. And she brought me this duty-free Toblerone.
Leonard: Oh. I love those.
Sheldon: (To Ramona) Let's sit somewhere else.

Raj: Actually, I was going to suggest me.
Howard: Great. Anybody's better than, (glancing at Stuart) mmm.
Stuart: Excuse me. They took out my spleen and gallbladder, not my feelings.

Howard: Should we do something about Nowitzki?
Leonard: Like what?
Raj: Well, she's single, so if somebody else asks her out and she says yes, then we know she's not into Sheldon.
Stuart: I'll do it.
Leonard: No offense, Stuart, but the woman's a doctor.
Stuart: So? Doctors like me. Whenever I see mine he calls in a bunch of other doctors to have a look.
Howard: She's not that kind of doctor.
Stuart: Oh. Well, her loss. I've been called a genuine medical oddity.

Raj: She's clearly having a working lunch and preferred to eat alone.
Ramona Nowitzki: Dr. Cooper, over here.
Raj: I could have made her very happy.
Leonard: You kept walking. I think you did.

Howard: How's Sheldon doing with Amy gone?
Leonard: Well, the last three nights I've had to take him to get a haircut, to the train store, and to a Walgreens in Arcadia where they still have the "good ibuprofen." Now, ask me how I'm doing with Amy gone.
Raj: How are you doing with-
Leonard: Shut up.
