Danny: You've done a terrific job with Inflaminex. We're always on the lookout for great salespeople. I think we could make you happy.
Penny: Uh, thanks, but I'm pretty happy.
Karen: I could be more happy.
Penny: Tell it to your shrink, Karen.

Danny: Zangen's a fine company. They got a couple of good drugs, but we control 60% of the market. Hell, commissions on just our fungal creams will put you in a new Mercedes.
Penny: Danny. Danny, look at me. Does this face sell fungal creams? No. This face is cholesterol drugs and above.
Danny: Playing hard to get, huh?
Penny: [laughs] No one's ever accused me of that before.

Bernadette: Danny, you rat bastard.
Danny: What? I'm just making your friend an offer.
Penny: Yeah, he's writing it on a napkin like in the movies.

Bernadette: Not only is she a helluva salesperson, she's the hardest worker I've ever seen.
Danny: I know, that's why I'm trying to steal her from you.
Bernadette: Well, then you're gonna have to do a lot better than this, because I promise you, I'm not gonna let her go without a fight.
Penny: You do not want that, she's a biter.

Amy: Hey, we just heard that you're the ones who convinced the Nobel Laureates to come.
Sheldon: Thank you.
Penny: You are welcome.
Leonard: You guys deserve this.
Penny: Yeah, now get out of here, go talk to some smart people.
Leonard: Wait a minute.
Penny: Yeah, sorry. Sometimes I forget you're smart because you're so sexy.
Leonard: I can see that.

Raj: You guys know that Hemingway had cats with six toes?
Penny: Six toes per foot or six toes total?

Leonard: Hey. I thought about what I want to do tonight, and I didn't take your feelings into consideration at all.
Penny: Great.
Leonard: I want to have sex.
Penny: Wow, sex with your wife. You're really swinging for the fences there, Hofstadter.

Leonard: So, I spent the whole day putting together this proposal, and tomorrow I'm gonna tell President Siebert that this is what I want to do.
Penny: Oh. Well, this looks great.
Leonard: You didn't even open it.
Penny: Well, no, it's got a nice, you know, science-y heft to it.

Penny: Sheldon, if this is what he wants, he should ask for it. I mean, what's the worst that happens? They say no.
Leonard: Well, I'm not gonna let them say no. If they don't want me to quit, this is what it's gonna take.
Penny: Wait, you're gonna quit?
Leonard: Yeah. It's like you said, I have to go after what I want, and if I can't get that at Caltech, there are plenty of other universities in the world.
Penny: W- In the world? I can't even get you to go to the beach, and now you want to move to the world?

Bernadette: I don't know. If someone's a cheater, they should be held accountable no matter how long ago it was.
Penny: Okay, now you just sound crazy.

Leonard: Well, if Sheldon and Amy don't want to expose Pemberton, that doesn't mean someone else can't do it for them. They'd never have to know.
Penny: Really? You'd do that?
Leonard: They deserve the Nobel. I'm not gonna let two frauds steal it from them. And if that means getting my hands dirty, so be it.
[Penny laughs]
Leonard: What's so funny?
Penny: Just realized I've never actually seen your hands dirty.

Leonard: Penny, can I have a moment alone with my?
Penny: Yep, bye.

Sheldon: All this change is just too much. The reporters, the attention at work, and now even Amy's changed. Whoa, whoa, whoa. Slow down.
Penny: I'm playing a drinking game. Every time you say the word "change," I take a slug.
Sheldon: Are you gonna be able to drive me home?
Penny: Mm. Not unless you change the subject. Huh. Now I said it. Meh.

Penny: You know, I've grown, too. I used to be the bartender back there.
Sheldon: That's true. And now there is a completely different woman who botched my drink order. How hard is 65% Coke, 35% Diet Coke?
Penny: Well, judging by the look on her face, it's at least one percent saliva.

Sheldon: Yes, Penny?
Penny: Oh. Do we have to go?
