Bernadette: So, Beverly, did you know Penny is the number three sales rep at our pharmaceutical company?
Beverly: Oh, I didn't realize you two worked together.
Bernadette: Well, we don't exactly. I'm a microbiologist for the research team.
Beverly: Oh, what are you currently developing?
Bernadette: Some exciting new anti-anxiety drugs.
Beverly: That's interesting. I just attended a lecture on pediatric anxiety.
Amy: Oh, was it, uh, Dr. Janofski? I just saw his TED Talk.
Beverly: It was.
Bernadette: Well, let's get back to Penny. Hey, weren't you telling me something great about your company car?
Penny: Um, it has seat warmers.

Leonard: What am I supposed to do?
Penny: Err, keep your mouth off other women.

Penny: At one point, they had me figure out how to get a banana out of a puzzle box.
Leonard: Wait, Sheldon gave me a banana in a box. He was testing me, too.
Penny: Unbelievable.
Leonard: And how could a chimp even solve that? That was impossible.
Penny: Really? You couldn't get it out?

Sheldon: Woman, you are playing with forces beyond your ken.
Penny: Yeah, well your Ken can kiss my Barbie.

Stuart: Anyone else need anything before I go?
Howard: I'll give you a dollar if you make fun of Raj.
Stuart: That's mean.
Howard: Five.
Stuart: You look like Tigger if Tigger looked like a jackass.
Howard: Uh, if you ever need a reference or anything, just let me know.

Penny: Helium.
Sheldon: Yes.
Penny: Yes.
Sheldon: Taylor Swift.
Penny: Yes. Pi.
Sheldon: Yes. Kardashian.
Penny: More specific.
Sheldon: Khloe?
Penny: Yes.
Sheldon: See, I remembered because if it looks like Kim it's Kim, if it looks kind of like Kim it's Kourtney, and if it looks nothing like Kim it's Khloe.

Penny: Oh, that's a Venn Diagram, and I remember because I thought to myself, "Venn is he gonna stop talking about this diagram?"
