Priya: Nice of you to come for Howard.
Penny: Well, he's my friend. It's what you do. (Laughs)
Priya: I'm sorry, did I miss something?
Penny: It's just so weird. Howard Wolowitz is my friend. You know, once he tried to stick his tongue down my throat and I broke his nose.
Priya: That's a little easier to believe than he's your friend.
Penny: Yeah, tell me about it.

Penny: You want to talk about crazy mothers, Leonard's mom wouldn't give him any sort of approval growing up.
Priya: Oh, the poor thing.
Penny: It makes him desperate to please women. That's why the foreplay goes on and on.
Priya: It does, doesn't it?
Penny: It's like he's trying to win a prize. A word of advice, don't doze off. You will never hear the end of it.

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: You can't put a saddle on Leonard Hofstadter. Oh, my, is it getting hot in here? Ay, papi.
Leonard: Ay papi? What is that?
Penny: An acting choice.
Leonard: Oh. So you chose that when you become turned on, you turn into Speedy Gonzalez?
Penny: Choo got a problem with that, papi?

Sheldon: Oh, come on. It's just a simple favor. Now, when's the last time I asked you to do something for me?
Penny: Yesterday. You made me look in your ear to see if there was a ladybug in it.
Sheldon: When is the last time I asked you to do something that wasn't a medical emergency?
Penny: Yesterday. You made me look in your ear to see if there was a ladybug in it.

Penny: You know, Amy, sometimes when you're in a relationship with someone you really care about, the sucky part is, it leaves you open to getting hurt.
Amy: Do you ever worry about Leonard doing that to you?
Penny: That's hilarious. No.

Penny: All right, then we're gonna have to go with an oldie but goodie, making a scene.
Amy: I don't think I'd be good at that.
Penny: That's why you're lucky to have me. Back in Omaha, there are two different restaurants I'm not allowed into. Both Chili's.

Penny: Sheldon, she wanted to show you off to her family, and you stood her up, okay? Look at this adorable, smushy face. Smush, smush, smush, smush.
Amy: You're hurting me.
Penny: No, Sheldon hurt you.
Amy: Before; now it's you.
Penny: Oh.

Penny: And that's how a girl makes a scene. I'm sorry, sweetie. You're right. You deserve your weekend. Come on, Amy, let's go.
Amy: What about the Science Center?
Penny: I'll let you hold my hair while I throw up.

Penny: Well, that, that's good. I'm glad you came to that. But before you do, let me just ask you a big picture question.
Bernadette: What?
Penny: Are you a hundred percent positive you love and want to marry Howard Wolowitz?
Bernadette: I do, with all my heart.
Penny: Got it. Just had to check.

Leonard: Well, what are you going to do, Sheldon, give up?
Sheldon: Yes. That's what a rational person does when his entire life's work is invalidated by a post-pubescent Asian wunderkind. He ceases his fruitless efforts, he donates his body to scientific research, and he waits to die.
Penny: You know, I'm confused again. Is he waiting, or do we get to shoot him between the eyes?

Penny: Is everything okay?
Bernadette: Look, I'm gonna tell you something, but you can't freak out, because I'm already freaking out.
Penny: Oh, my God, what is it?
Bernadette: I'm pregnant again.
Penny: (excitedly) Wha-? ... (quietly) Interesting.

Penny: Okay, look, look, this is a good thing. Halley's gonna have a little brother or sister to play with.
Bernadette: I guess that would be pretty cute.
Penny: And, you, know, I was a surprise to my parents, and my dad said it was the best thing that ever happened to them.
Bernadette: Okay. Maybe this baby actually is a blessing.
Penny: Oh, my God, honey, of course it is.
Bernadette: (exhales) How am I pregnant again?
Penny: Yeah, what were you thinking?

Penny: Okay, where is this coming from?
Sheldon: It has been suggested to me that acting techniques could improve my lecturing, at which, if certain tweets and blogs are to be believed, I suck the big one.
Penny: Yeah, I saw those. They were funny. I printed a few out and put 'em on my fridge.
