Penny: All right, my advice to you is do it at her place so you can leave when you need to. Uh, tell the truth, make it quick and be prepared for tears.
Raj: Oh, I'm gonna do a pre-cry before I go in there. Really dry myself out.
Leonard: She meant Emily.
Penny: No, I - I really didn't.

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?

Amy: Hi. You're on Fun with Flags.
Barry Kripke: Hello. I want to talk about how lonely I am, too.
Raj: Kripke? Is that you?
Barry Kripke: Yeah, I'm just sitting here all by myself wondering if I'll ever find someone to share my life with. Preferably Asian, 18-24, no fatties.

Sheldon: Oh, and speaking of Valentine's Day, I haven't forgotten about you tonight.
Amy: What do you mean?
Sheldon: Well, you've become such an integral part of my life as well as this show, I felt it only right to include your name in the title.
Amy: Oh, that is so sweet.
Sheldon: So from now on, this program will be officially known as Dr. Sheldon Cooper and Dr. Amy Farrah Fowler present Dr. Sheldon Cooper's Fun With Flags.
Amy: Catchy.

Amy: Since we're live, you'll finally be able to reach out to us with your flag thoughts and flag questions.
Sheldon: Allow us to answer a few quick ones that we get all the time. Uh, yes, I really am a doctor. Uh, yes, she really is my girlfriend.
Amy: No, I just blink a lot, it's not Morse code for "rescue me."
