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.

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

Penny: So, Sheldon, have you talked to Amy?
Sheldon: Yes, we Skyped this morning and I'm sure I'll check in with her before I go to sleep.
Ramona Nowitzki: Sheldon talks about her all the time. I can't wait to meet her.
Sheldon: That is true. She keeps asking how long Amy's going to be gone.

Penny: Not only did they eat together, Leonard said he made her laugh.
Bernadette: That's nothing, Howie said she touched his hand.
Penny: Did he Purell?
Bernadette: No.
Penny: I cannot believe Leonard mentioned the Toblerone but left that part out.

Amy: I gave you one job! Keep an eye on him. How hard is that?

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.

Sheldon: That was fun. It was like Mario Kart.

Leonard: Uh, so, Ramona, tell us about yourself. Do you, do you have a boyfriend?
Sheldon: Leonard, your wife is sitting right here. What are you doing?

Sheldon: And get this, I saw an articulating ladder with dual-leg leveling, which delivers stability and adaptability to uneven terrain.
Amy: Sounds like a big night.
Sheldon: Yeah. Raj made the funniest joke, he said, "Which is the best ladder to use to hang myself?"

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

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.

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.

Sheldon: I've learned some fun facts about New Jersey to help you make small talk. Would you like to know the state bird or the murder rate? They're both shocking.
Amy: Actually, I want to hear about you. How are things at home?
Sheldon: Well, I'm a lot less likely to see an Eastern Goldfinch or be murdered, I'll tell you that.

Sheldon: So, tell me about your scalar dark energy experiment.
Ramona Nowitzki: Not 'til you tell me about your latest paper on quantum loop theory.
Sheldon: Oh. You must be one of those dessert before dinner people.

Raj: We're being ridiculous. There's no way a woman that attractive is trying to seduce Sheldon Cooper.
Howard: You done trying to make yourself feel better?
Raj: No. I haven't played the race card yet.
