Penny: Got it. Hey, who's the murderer?
Raj: Any question but that.
Penny: Sorry. Hey, who's not the murderer?

Penny: Hey, listen, what if we have a little mother-in-law, daughter-in-law dinner tonight?
Beverly: So just the two of us?
Penny: Or I invite a few girlfriends, 'cause hearing you say the two of us just sent a chill right down my spine.

Penny: There's not even a bathroom on set. I have to go to the gas station across the street. I mean, I was dressed like half an ape and still not close to the most disgusting person in there.

Penny: You know what, maybe I need a break from all of you. Come on, Sheldon.
Sheldon: Where are we going?
Penny: We're going to have Anything Can Happen Thursdays, you're going to tell me all about your science stuff and I'm going to complain about my movie, and we're going to support each other because that's what friends do.
Sheldon: Okay. Because if I had to pick now, I'd probably go with dark matter-
Penny: Shut. Up.

Howard: I'll take the apartment upstairs. I can finally get away from my mother, and we can spend some more time together, if you catch my drift.
Penny: The horror.

Penny: There, nice and comfy cosy. Zero, zero, zero.
Sheldon: There's one more zero. You forgot the time parameter.
Penny: Sit on the damn couch.

Leonard: Was Amy suspicious when they had to let your dress out?
Penny: No. She was so happy, she didn't even question it.
Leonard: Someone's gonna figure it out. Why don't we just tell people?
Penny: No, it's too early. I haven't even wrapped my head around it.
Leonard: I have. My head is wrapped.
Penny: Yeah, well if something else had been wrapped, we wouldn't be in this situation.

Penny: No, it's not that.
Bernadette: Then why?
Penny: Honestly, I don't know if I'm up to it. You know, the last project I managed was my high school yearbook.
Bernadette: And?
Penny: And that was the year we didn't have one. - And? And that was the year we didn't have one. Apparently, the printers won't make them without getting paid.
Bernadette: What happened to the money?
Penny: Uh, if I didn't know then, I'm not going to magically know now.

Penny: You guys should've seen Leonard when I first met him. There was no eye contact. He was either looking up at the ceiling, or down at his shoes.
Amy: I'm drunk.
Penny: You know, for the first couple of months, whenever I would take off my bra, he would giggle and say, oh boy, my breast friends.

Penny: Hi. We're just heading out for a drink.
Amy: Because I do that now.
Bernadette: Count your blessings you're not a Tanzanian chimp.
Priya: What?
Penny: Don't listen to her, she's had a lot of ice cream.

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.

Penny: There's got to be something fun we can do that the guys will hate.
Leonard: Hang on, why do we have to hate it?
Penny: Three words: Doctor Who convention.

Penny: Hey, what you doing?
Leonard: Oh. Sheldon gave me a brain teaser. It's kind of fun. It's about a group of people at dinner, and you have to figure out where they can sit without fighting.
Penny: Oh, yeah, is this the one where Mr. Green can't sit next to anyone eating meat, and Uncle Light Blue won't sit next to any of the darker colors?

Penny: (On the phone) Anyway, I'm really sorry I made fun of your stutter in high school.
Bernadette: You're doing great.
Penny: Uh-huh. Uh-huh. Oh, God, just finish the sentence. Okay, well, I'm sorry you feel that way. Bye. No one wants to hear my apologies.
Amy: I think your mistake is doing it over the phone. If they could look into your eyes, they'd melt.
Bernadette: Penny, it doesn't matter what you did in the past. You're a good person now.
Penny: That's easy for you to say. You weren't just called a b-b-b-b-bitch.
