Bernadette: Oh, I don't know. I don't want to manipulate him with sex.
Penny: Oh, sweetie, that's what sex is for.

Penny: You know I'm a big believer in breaking bad news to a guy when you're in bed with him. That's how I told my high school boyfriend I slept with his brother. That's how I told his brother the same thing.

Howard: I'm not signing a prenup.
Penny: All right, Howard Wolowitz, listen up! You sign anything she puts in front of you, because you are the luckiest man alive. If you let her go, there is no way you can find anyone else. Speaking on behalf of all women, it is not going to happen, we had a meeting.

Leonard: Is that your laundry? You only have, like, six things in there.
Penny: Yeah, I didn't have any quarters, so I've been sneaking stuff into other people's loads all day.

Penny: I think about a lot of things. I think about us getting married, I think about us breaking up. Once in a while, I think about how I didn't leave a note on that Mercedes I dinged in the parking lot last month, but then I have a glass of wine and it passes.

Penny: Sheldon, that's not what girlfriends are for. Although you don't use them for what they're for, so what do I know?

Penny: Oh, good, your power's out, too.
Leonard: Why is that good?
Penny: Because last month, I sent the electric company a Starbucks gift card, an apology note, and a few snapshots of me in a bra.

Penny: Bug report: when a guy asks me to spend some time with him, maybe he plans something a little more interesting than hanging out at home and watching TV.
Leonard: Even Doctor Who?
Penny: Even Doctor Who.

Penny: You mean like a beta test?
Leonard: Well, technically, this would be an alpha test. A beta test requires people that weren't involved in the development of the appli-
Penny: Seriously, do I not get credit for knowing beta test?
Leonard: No, absolutely you should.

Penny: No, your Reebok has a gunshot wound and you have an ouchie on your pinky toe.

Penny: You mean, like a date?
Leonard: Not like a date, a date.

Leonard: So, do they have a name for a first date with someone you used to go out with?
Penny: Oh, that's a good question. How about awkward?
Leonard: Yeah, that sounds right.

Penny: Okay, uh, let's see. I'm from Nebraska, and ever since I was a little girl, I dreamed of moving to L.A. and becoming a movie star. Anyway, after four years of acting lessons and waiting tables, I've done a hemorrhoid commercial and a production of Anne Frank above a bowling alley. So, you know, dreams do come true.

Penny: So, are we celebrating anything special tonight?
Amy: Oh, yes. Our relationship agreement specifies that the second Thursday of every month, or the third Thursday in a month with five Thursdays, is date night.
Penny: That is so hot.

Penny: Did Sheldon change the Wi-Fi password again?
Leonard: Yeah, it's "Penny already eats our food she can pay for Wi-Fi". No spaces.
