Penny: Wow. Didn't even make it out of the parking lot. Uh, you know what, enough about Leonard. Let's talk about you. What would you like to do while you're here?
Beverly: Dear, I'm a psychiatrist. You don't have to avoid having intimate conversations with me.
Penny: Well, I'd actually like for us to be close, but maybe we start with our favourite books and work our way up to my husband's sex organs.
Beverly: Very well. What's the last book you read?
Penny: Um, does Pottery Barn, Spring count?

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

Raj: [to Amy] If you were having Sheldon's baby, would you really want him in the room?
Penny: Yeah, if he's in the room when they're making the baby, I'll give you $10.

Penny: I mean, who even reads Scientific American?
Leonard: It's kind of a big deal.
Penny: If it's such a big deal, how come the biggest celebrity they could get for the cover is a molecule?

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.

Raj: Boy, all this standing's making me tired. Good thing I brought my collapsible stick chair.
Howard: Not the stick chair. You look like an idiot on that thing.
Raj: Sticks and stones may break my bones, but chairs on sticks are comfy.

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.
