Penny: You're okay with an experiment where you have to answer awkward questions about your innermost feelings?
Sheldon: Yes.
Penny: Please can I do it with him, please.

Penny: We're putting the play on for one night in this little 99-seat theater. Can you come? Oh great! Do you know 98 other people that might want to come?

Amy: I'm dating Sheldon Cooper
Penny: Yes. On purpose.
Amy: He's handsome, he's lanky, he's brilliant, and his skin has that pale, waxy quality.
Penny: Well, sickly is the new sexy.

Bernadette: Stuart took that rejection like a pro.
Penny: Well, he knew he was on the breast cam.
Amy: I don't have much practice turning men down. It wasn't so much fun.
Bernadette: Oh, you get used to it. Some guys you have to turn down over and over.
Penny: And sometimes we marry them anyway.

Penny: That top has paid off in free drinks 10 times what I originally paid for it.
Sheldon: Yes, Penny has a lot of money tied up in promiscuity futures.

Penny: Sorry, Stallion. Your weird friend Giraffe is here.

Penny: Since when do we offer one day rush?
Leonard: Amazon offers one day rush.
Penny: Yeah, but they don't have to glue the books together!

Penny: Honey, you don't have to thank me every time we have sex, sweetie.

Penny: Amy, little vixen. Just working it under all those layers of wool and polyester.

Penny: So, I guess the only thing that actually stays the same is that things are always changing.
Sheldon: Interesting. So you're saying the inevitability of change might be a universal constant.
Penny: Well, there's a little more to it than that, but, yeah, sure.

Penny: What up moonpie!

Penny: What are you saying? That I'm using my body to get dinner? That I'm some sort of Chinese food prostitute?

Raj: Oh, the movie's not as bad as you thought?
Penny: No, it is. But I decided instead of complaining about it, I'm going to go in every day and give it my all.
Amy: Good for you.
Penny: Thanks. There's no reason why I shouldn't be the best bi-sexual, go-go dancer, slowly transforming into a killer gorilla, anyone's ever seen.

Sheldon: I've never played Dungeons and Dragons with girls.
Penny: It's okay, honey, no one has.

Penny: And remember, he's more afraid of you than you are of him.
Sheldon: That doesn't help.
Penny: No, I was talking to the bird.
