Penny: Well, Amy, looks like the elevator might have been the high point of your day.

Penny: By tomorrow, I want everyone to have this committed to memory.
Karen: Do you have it committed to memory?
Penny: You want to have a contest, Karen? Winner gets a yogurt.

Bernadette: Mm, it's probably for the best. I need someone who's strong and confident to head up my sales team, so I'm giving it to Karen.
Penny: What Karen? Well, what's the job? Eating my yogurt and then lying about it?

Bernadette: So, I talked to your supervisor, and she said that she never stopped you from working on my team, because you never asked her.
Penny: Really? Oh, you know, you should know, she's been taking our new antidepressant, and lying is one of the main side effects.

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.

Leonard: I am so proud of you.
Penny: Well, I know how to do the dishes. Just, sometimes I'm tired.
Leonard: No, I-I mean, I'm proud of how well you're doing at work. Are you even using soap?
Penny: Do you want to do this?
Leonard: Yeah, I really do.

Amy: You guys will never believe what just happened.
Raj: Yeah, we heard. You did it.
Sheldon: We did do it.
Amy: And we didn't even know we did it!
Howard: Wait, what?
Sheldon: Two physicists in Chicago had to tell us.
Leonard: Wait, what?
Sheldon: Their experiment on kaon decay supported our predictions on the higher order corrections pertaining to super-asymmetry.
Penny: Wait, what?

Amy: A team of physicists confirmed super-asymmetry. Our paper was right. We did it.
Sheldon: We did it?
Amy: We did it.
Sheldon: We did it.
Both: We did it! We did it! We did it!
[in the hallway:]
Penny: Aw, remember when they only did it on her birthday?

Leonard: All right, look, um I'm sorry that we fought before. I know this is a really unusual situation, and if you don't want me to do it, I won't.
Penny: Really?
Leonard: Yeah. We're a team. We're in this together.
Penny: I'll be right back.
Leonard: What is that?
Penny: It's a sample cup.
Leonard: Really? 'Cause it looks like the top off the NyQuil bottle.
Penny: It's the closest thing I could find. It's a gesture. Shut up.

Leonard: Are you jealous?
Penny: I know, I know, I shouldn't be. He's super sweet. I should be happy for them.
Leonard: Oh, it's driving me crazy, too.
Penny: Really?
Leonard: Yes. I was trying to pretend like it wasn't so you wouldn't think I was petty.
Penny: Wha-- turns out we're both petty.
Leonard: I love you so much.
Penny: Aw.

Marissa: And Zack's always admired you because you're the smartest person he knows.
Penny: Okay, whoa, whoa. Whoa, whoa. You know, this has been such a nice evening. Let's all just stop before anyone says any more things.
Zack: Leonard, would you be the father of our baby?
Penny: Aw, you said a thing.

Marissa: And Zack's always talked about what a great guy Leonard is.
Leonard: I (chuckles) I really don't know what to say.
Penny: Really? You don't know what to say?

Penny: How was game night?
Leonard: Oh, off the charts. Literally. Sheldon rolled a number so high, it wasn't on any of these charts.
Penny: (laughs) That's funny. Wow. I should not have driven home.

Penny: Oh, hey, how did your interview go?
Amy: Okay, I guess.
Penny: You don't sound very happy.
Sheldon: Oh, why wouldn't she be happy? She's the neurobiologist who revolutionized physics.
Penny: Sorry.

Penny: All right, I take Bernadette.
Howard: Really? You're picking her over me?
Penny: Yeah, 'cause she's vicious and can hide behind a mushroom.
