Leonard: You know we could throw a dinner party too. Maybe even ask everyone to get dressed up.
Penny: Sure. Just when you say dressed up, you mean nice clothes, right? Not like capes and tights and crap
Leonard: Yes. Although...
Penny: No.

Leonard: How was Nebraska?
Penny: Oh, better than North Dakota! [silence] I guess that joke's only funny in Nebraska.
Sheldon: From the data at hand you really can't draw that conclusion. All you can say with absolute certainty is that that joke is not funny here.
Penny: Boy, it's good to be back.

Penny: Hey, Leonard, if you're not busy tomorrow, I have to do a little reception after work.
Leonard: Oh, I would, but we need to make a push on the air force project.
Penny: Oh, are you sure? We're celebrating our new A.D.D. drug, and it'll probably be over in, like, six minutes.

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: You are not a burden, and we want you to come back and stay with us.
Raj: But I also upset Sheldon, and he's not gonna want to come over if I'm there.
Penny: More reasons for you to stay.

Bernadette: You're still gonna go, right?
Amy: I don't know. Sheldon's so vulnerable right now.
Penny: Oh, come on. Look, if the roles were reversed, he'd be on the first train to New Jersey. Or the second train if there were teenagers on the first one.

Leonard: Look, just because we took our friend in does not mean that Penny and I are afraid to be alone.
Penny: Yeah, this is a special circumstance.
Beverly Hofstadter: Sheldon mentioned you tried to get your brother to live with you, as well.
Penny: Yeah, well, a circumstance can happen twice and still be special.

Raj: Wait a minute. Hey, let me see your phone.
Sheldon: Why?
Raj: Well, it's possible it was tracking everywhere you went.
Amy: Phones can do that?
Raj: Yeah, it depends on the privacy settings.
Penny: Oh, tha- that's so cool. How do you- how do you turn that thing off? (laughing nervously)
Leonard: Relax. I know when you "go for a run," you stop for a donut.
Penny: I don't even run there, I drive.

Leonard: We're helping Raj figure out his finances.
Penny: Well, he has a job. How bad can it be?
Sheldon: Well, his rent and car lease are exceedingly high. You couple that with his penchant for dining out and shopping-
Penny: Wait, wait. Not shopping for clothes, right? Because look. (points to Raj)

Penny: That must've been expensive.
Raj: Yeah, it was. But it's my father's money and I'm mad at him.
Leonard: What's going on with your dad?
Penny: And if you really want to hurt him, I look great in Chanel.

Sheldon: Amy, you should know I was never really interested in seeing other women. And to prove how serious I am about us, I'm willing to take our relationship to the next level.
-Cut to Sheldon and Amy's bathroom in Apartment 4B-
Sheldon: Amy Farrah Fowler, will you share this toothbrush holder with me?
Amy: I would love to.
Leonard: Did we really need to be here for this?
Penny: Call me crazy, but I found it moving.

Leonard: Don't you have any friends he can date?
Penny: Hey, I already set up Howard and Bernadette. It's your turn to ruin some poor girl's life.

Penny: Hey, you ready to go?
Leonard: Yeah, I guess.
Penny: What's the matter?
Leonard: Honestly? It's a little strange having dinner with your ex-boyfriend, and it's not like we have a lot to talk about.
Penny: What? He loves you, okay? And he's interested in your work. You could talk about the infinite perspective -- I swear I know it.

Leonard: Which is why I got you this Pink Power Ranger. Put it anywhere you like.
Penny: Okay, but you may feel some discomfort.

Penny: What do you think? Should we go to a hotel?
Leonard: And just leave him here alone?
Penny: Okay, I'll go to a hotel. Text me in the morning if you're still alive.
