Sheldon: Raj?
Raj: Spending Valentine's Day with Emily.
Leonard: You don't sound very excited about it.
Raj: Oh, I am, I am. I g... I guess I'm still wondering if Emily and I are right for each other.
Howard: Does this have to do with that girl you had coffee with?
Raj: You mean the strong, sexy angel I can't stop thinking about? Who can say?

Raj: Amy, good luck getting these guys excited about a dinner with a theme. I gave up when no one cared about my Tom Hanks-Giving.

Raj: Oh man, first monster I see I'm gonna sneak up behind him, whip out my wand and shoot my magic all over his ass!
Stuart: Do you hear yourself when you say these things?

Raj: Doesn't anyone have a rod of resurrection? Because if you've got one, I need it bad. Get in here with your rod and give it to me.
Stuart: Okay, you need to say these things in your head before you say them out loud.

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."

Raj: But, Amy, when you and Sheldon split up, didn't you start dating someone right away? Amy: Well, I ... I wouldn't say right away.
Sheldon: And actually, it was three different men.
Barry Kripke: Three different men?! Damn, girl, way to give the milk away!
