Penny: I just got a part on a TV show.
Amy: Congratulations!
Leonard: That's great. Guys ...
The guys: Yeah ...
Amy: What's the show?
Penny: NC - I I? or, you know, NC - S T D. I don't know. It's the one with all the letters.

Leonard: We cover ourselves in body paint and then we get on this big canvas and do our thing.
Penny: Woah, that's kind of a big step for a guy who only recently agreed to take his socks off.

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?

Leonard: She's only been here a day and a half, and I'm seriously considering alcoholism as a new career path.
Penny: Hey, I talked to her for five minutes yesterday, and I've been half bombed ever since.

Raj: Ooo.
Penny: What's the matter, Lassie? Did Timmy fall down the well?

Sheldon: Here's an interesting fact about alcohol: Man is not the only species that ferments fruit in order to become intoxicated. Can you guess what the other is? Hint: sometimes they pack the alcohol in their trunks.
Penny: Monkeys.
Sheldon: When does a monkey have a trunk?
Penny: When a suitcase just won't do.

Penny: Don't you dare knock!

Leonard: Wow, Penny, you're on fire!
Penny: Yeah, so is Sheldon!

Leonard: Don't you think if a woman was living with me I'd be the first one to know about it?
Penny: Oh, sweetie, you'd be the last one to know about it.

Leonard: Before you say anything, have you heard of Schrodinger's cat?
Penny: Actually, I've heard far too much about Schrodinger's cat.
Leonard: Good.
*Leonard and Penny kiss*
Penny: All right, the cat's alive. Let's go to dinner.

Leonard: They're gonna get beaten up at that club.
Penny: They're gonna get beaten up at Walgreens.

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.

Penny: Holy crap on a cracker!

Penny: And what kind of doctor removes shoes from asses?

Penny: (To Howard and Raj) So either one of you weirdos wanna buy my underwear? Only 1400 bucks.
