Leonard: Tonight he wants to look at ladders at Home Depot.
Raj: Oh, why does he need a ladder?
Leonard: He doesn't; he just likes looking at them. Bring a book.

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.

Leonard: Wait, isn't she the grad student that used to follow him around?
Howard: Oh, yeah. Back before he hit puberty and grew man parts.

Leonard: He just made her laugh, something's wrong.
Raj: Do you see the way she's looking at him?
Howard: Yeah. Like Bernadette used to look at me.
Raj: I keep telling you, close the bathroom door.
Leonard: Ah, did you see that? She just touched his hand and he didn't swat it away. What is happening?
Howard: Okay, the simplest explanation is usually the right one.
Raj: Which is?
Howard: That ain't Sheldon.

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: Well, what do you want us to do?
Amy: I don't know. Might be the New Jersey talking, but this Nowitzki broad needs to disappear.

Howard: It's unbelievable. Sheldon has lunch with another woman and somehow my wife yells at me.
Leonard: Penny laid into me, too. Apparently, I'm overly fixated on premium Swiss chocolate bars.

Raj: Can you even eat those things?
Leonard: If I take a Lactaid a half-hour before and some Pepto right after.
Raj: Sounds like a lot of work.
Leonard: Eh, I'm worth it.

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: Dr. Nowitzki. Good to see you.
Ramona Nowitzki: Good to see you, too.
Raj: May I join you?
Ramona Nowitzki: No.
Raj: Good to see you.

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.

Ramona Nowitzki: I was proud of him. A lot of people don't put their face in the water on the first day.
Sheldon: Well, I was hiding from a bee, but it still counts.

Ramona Nowitzki: Are these all from Peter Higgs?
Sheldon: Hmm? Oh, no, no, no. They're from many famous people. See? Oh, like this one. This is from Patrick Stewart. It says if I come to his house again, I get to meet his dogs.

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

Ramona Nowitzki: Hey, did you eat yet?
Sheldon: Uh, breakfast yes, lunch no. I did have a cough drop, but that really rides the line between sucking and eating.
