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.

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.

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: 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.

Penny: Do you think living with Amy has somehow stirred up Sheldon's sexual appetite?
Bernadette: (grimacing with disgust) Ugh. How can you think that? Why would you even put those words together?

Howard: If you'd like, we can help you out.
Leonard: Oh, that would be great.
Howard: I mean, not me, I've got a wife and child, but this one posts video of himself flossing on Instagram.
Raj: It was a tutorial. And yes, I'm happy to keep Sheldon company.

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: What is Leonard doing calling you at this hour?
Amy: It's not important.
Sheldon: I must tell you, that seems a little inappropriate. Don't you agree?
Ramona Nowitzki: I do.
Sheldon: See? We both think so.

Sheldon: Because there's only one of me, I'm more valuable.
Penny: Right.
Sheldon: Although, Amy's already taken me out of my package and played with me.

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

Sheldon: *knock knock knock* Amy. *knock knock knock* Amy. *knock knock knock* Amy.
[Amy opens the door. Sheldon is on one knee, holding out an engagement ring]
Sheldon: Will you marry me?

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.

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.

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.
