Sheldon: Indeed. Penny, a salon is a gathering where intellectuals entertained each other with sparkling conversations about the issues of the day.
Penny: Huh. So it's like The View.

Penny: Are you getting sick?
Sheldon: Of course not. I'm too busy to be sick.
Penny: Well, you're pretty delicate. Maybe you shouldn't be pushing yourself so hard.
Sheldon: I'm fine.
Penny: All right. We'll just pretend that you didn't catch a cold watching Frozen.
Sheldon: That didn't happen.
Penny: You also got a nosebleed watching Up.

Sheldon: The Hungarians are just using you for dragon fodder.
Penny: Really? Boy, you'd think you could trust a horde of Hungarian barbarians.

Penny: Yeah, and you certainly don't have to earn my love.
Leonard: Thank you.
Penny: Of course you already knew that when you bought me this princess-cut drill bit.

Bert: It makes sense you two are friends. I mean, hot girls always stick together.
Amy: And you thought this wasn't gonna be a great party.
Penny: You know, I had no idea Caltech is exactly like my high school.
Amy: Well, it's not exactly like it. We're all extremely smart.
Penny: Wow. You popular girls are mean.

Leonard: Hey.
Penny: Hi, how was the screening?
Leonard: Oh, Sheldon invoked Rosa Parks to make somebody who cut the line feel bad, but only the white people felt bad.
Penny: Ugh, I should've never bought him that colouring book that explains Black History Month.

Leonard: Well, I can't read your mind, Penny!
Penny: Really? Why not? You're so smart, and I'm so dumb.

Penny: Bernadette, for every episode of Doctor Who Leonard has made me sit through, I will play on your behalf and send that TARDIS back to Gallifrey, where I hate that I know it belongs.

Amy: I guess this is what we get for being with two testosterone-fueled alpha males. At some point, they're bound to lock horns.
Penny: I'm assuming these are some kind of horns they bought at Comic-Con?

Penny: Get away from me or I swear to God I will rip out what's left of your pubes!

Leonard: Don't make it sound childish. It's the scientific word for dust.
Penny: What was wrong with "dust"?

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.

Leonard: Penny's gonna call her dad and tell him it's not a good time for Randall to visit.
Penny: Hopefully, he won't be too upset.
Leonard: Oh, you're his little girl. He can't stay mad at you.
Penny: He won't be mad at me. I mean, you're the one who doesn't want my brother to come, so-
Leonard: So you're gonna throw me under the bus?
Penny: Oh, I'm gonna throw you so hard, I might actually win a stuffed animal.

Leonard: Poor Mr. Fowler, I really feel sorry for the little guy.
Penny: I know. After they had Amy, she should've just eaten him and been done with it.
Leonard: Look at you retaining facts from a nature show.

Leonard: It's just a day trip, but we could take the ferry out to Catalina.
Penny: Great, let's do it.
Sheldon: (rushing in to the apartment) Amy's in the bathroom and I need to - (retches, bathroom door shuts, vomits loudly)
Penny: It's like I can hear the ocean already.
