Penny: Hey! Shouldn't you be out with your gang spray painting equations on the sides of buildings?

Wil Wheaton: Hello, caller, you are on with Penny and Wil from Serial Ape-ist 2.
Woman on phone: I don't have a question. I just want to say I'm a big fan of the movie. I've seen it, like, ten times.
Penny: Okay, well, I'll apologize for the first time, but the other nine are on you.

Amy: So, Penny, how's married life?
Penny: Oh, it's good. I just wish Leonard would work up the courage to tell Sheldon he's moving in here.
Bernadette: You guys still aren't living together?
Penny: We are. I mean, he sleeps here. But it's only a matter of time before Sheldon has a bad dream and tries to climb into bed with the Leonard-shaped pile of pillows.

Leonard: I don't understand why we're leaving so early for the movie.
Penny: Oh, I forgot to tell you, we're gonna meet up with Bernadette to spy on Amy and her date.
Leonard: What? I don't want to do that.
Penny: What, and you think I want to see a documentary about aluminum can recycling?
Leonard: This is the movie Big Soda doesn't want you to see.
Penny: No, it's the movie your wife doesn't want you to see.

Penny: Here, have some pizza, sweetie.
Leonard: You know I'm lactose intolerant.
Penny: I know; I just need you to stop talking.

Penny: What's thoughtful is everything you do. Here, look at this. This is the plane ticket you bought me when I was too poor to go home for the holidays. And the rose you left on my windshield just because. Here's the thank you letter you wrote me after the first time I slept with you. All eleven pages of it.
Leonard: I can't believe you saved all this stuff.
Penny: Of course I did, it's you.
Leonard: Come here. ... Is that a pregnancy test?
Penny: Oh yeah, just the first one. I didn't save them all.

Penny: (Reading tweet) "Listening to Dr. Cooper has made me wanna start cutting myself again."

Leonard: Can I sleep on your couch tonight?
Penny: Well, you can try. But the neighbors across the hall are being very noisy.
Leonard: Oh, you heard that, huh?
Penny: Yeah, apparently the one fella changed the thermostat, and then the other fella went bat-crap crazy.

Penny: Ok, who wants syrup & who wants powdered sugar?
Sheldon: I want oatmeal.
Penny: Well, I want a boyfriend whose roommate isn't a big pain in the ass.
Sheldon: I'm sure that will happen soon enough.

Penny: You can't tell her what she can or can not do.
Sheldon: Last week you told Leonard he couldn't wear his wookie jacket out in public.
Penny: That's different. I'm not going to the mall with somebody dressed like a dumb space bear.

Penny: I'm serious. Who wants to do all that stuff? Have insurance, pay mortgages, leave one of those little notes when you hit a parked car.
Amy: I told you it was Penny.
Penny: Oh come on. It wasn't me. Anybody could have knocked your mirror off. Or whatever happened.

Stuart: How's it going?
Raj: Good. Sheldon's out of town so we can do whatever we want. We even ordered from the Thai place he doesn't like.
Stuart: How is it?
Penny: Disgusting. Do not tell him.

Wil Wheaton: Well, I've certainly taken some jobs I've been embarrassed by.
Penny: I wouldn't exactly call Star Trek embarrassing.
Wil Wheaton: I wasn't.
Penny: Me either.

Bernadette: You're not working. How'd you like a job in home healthcare?
Penny: Not a chance.
Bernadette: Please, I'm desperate.
Penny: No.
Bernadette: I'll pay anything you want.
Penny: Okay then, yeah.

Penny: So, whichever rep has the best sales for the quarter gets a trip for two to Hawaii.
Amy: That would be so romantic for you and Leonard.
Penny: Yeah, clearly you haven't seen him on the beach walking around with his metal detector.
