Penny: Not really a great outfit for work. Unless something opens up in the Hookers & Whores department.

Leonard: I thought this was gonna be boring but it's actually kinda fun.
Penny: Don't tell Amy that; we'll be here every Sunday.

Penny: So, if you don't mind me asking, do you think you might start dating again?
Dr. Koothrappali: It's much too soon for that. Why, do you know someone?
Penny: No, but if things don't work out with me and Leonard, I'll call you. Wait, how much do you talk about Star Trek?

Penny: It's kinda boring. Although it did get exciting for a minute when Amy inhaled a wool ball.

Dan: Well one thing I've been meaning to tell you, is that the company's gonna stop paying for our coffee.
Bernadette: No problem. When does that start?
Dan: Five months ago.
Bernadette: What? Who's been paying for my coffee.
Dan: All of us.
Penny: Yep, it comes from the swear jar we put money in when you curse.

Sheldon: Why would you have surgery?
Leonard: Because I can't breathe. I snore. I get sinus infections.
Penny: Back off, he's all mine.

Amy: Don't be like that. You two need to talk this out.
Penny: Yeah, because you sound really funny.

Penny: What kind of teenager did you think I was?
Bernadette: Slutty.
Amy: Easy.
Penny: The word is 'popular'.

Amy: You went to seven proms?
Penny: Yeah. Let's see, four "under the seas", two "enchanted evenings", and one night to remember - that I can not remember for the life of me.

Sheldon: There are post-prom mating rituals?
Penny: Not always. Unless your date drives a van with an air mattress, then always.

Bernadette: So what are you working on these days?
Amy: I'm studying one-celled organisms to try and find the neurochemicals that lead to the feeling of shame.
Bernadette: What would a one-celled organism have to feel ashamed about?
Penny: Same as all of us. Getting out of a car without underwear.

Penny: You know, maybe if fashion magazines had female scientists in them, I would have become a theoretical physicist. Stop smirking at each other!

Penny: Hang on. You guys are going to work in a mine?
Sheldon: Why not?
Penny: You had a panic attack when we went through the car wash!

Leonard: Hear me out. I know things got a little weird last night.
Penny: Well, leaving an envelope of cash on my night-stand after sex would count as weird.

Leonard: She made him a chore chart.
Penny: I see it!
