Sheldon: There once was a brave lad named Leonard.
With a fi fi fiddle dee dee.
He faced a fearsome giant.
While Raj just wanted to pee.

Sheldon: I trust Leonard satisfied you sexually last night.
Leonard: Oh good God! Sheldon we don't ask questions like that!
Sheldon: I heard you ask it over and over. How is it inappropriate for me to ask it once?
Stephanie: He did very nicely.
Sheldon: See? She's not offended. And now you finally have an answer.

Sheldon: Why does Leonard get to go?
Wolowitz: Because he's upset over his situation with Penny, and if I have to hear about it again, I'm gonna kick him in his ovaries!
Leonard: Thanks for understanding.
Howard: I've got your back, sister!

Sheldon: And then you put it back, compromising the rest of the onion rings.
Penny: Aw honey, the buses don't go where you live do they?

Sheldon: Who's Nowitzki?
Ramona: I'm Nowitzki.
Sheldon: Oh, so you want me to share credit with you?
Ramona: Uh huh.
Sheldon: Get out!

Sheldon: You are effectively paying yourself five dollars and nineteen cents a day.
Penny: A day?
Sheldon: There are children working in sneaker factories in Indonesia who out-earn you.

Sheldon: If I would give you this gift basket, based on that action alone and no other data, infer and describe the hypothetical relationship that exist between us.
Store Clerk: Excuse me?
Sheldon: Here. Now, are we friends? Colleagues? Lovers? Are you my grandmother?
Store Clerk: I don't understand what you're talking about and you're making me a little uncomfortable.
Howard: See? Sounds just like you and Penny. We'll take it.

Raj: Hey, buddy, I'm gonna be in People Magazine.
Charlie Sheen: Yeah, call me when you're on the cover.

Sheldon: You know, I do recall seeing some female undergarments. Where was that? Oh, yes. Earlier this evening, I happened to gaze out the window and a brassiere caught my eye. Do those look familiar?

Penny: This has gotten way out of hand, okay. I've done some stupid things, you've done some stupid things. How about we just call it even, and move on with our lives?
Sheldon: I've done no stupid things.
Penny: Look, you've gotta meet me halfway here.
Sheldon: I am meeting you halfway. I'm willing to concede that you've done some stupid things.

Raj: Dr. Gablehouser.
Dr. Gablehouser: Dr. Koothrapali.
Leonard: Dr. Gablehouser.
Dr. Gablehouser: Dr. Hofstadter.
Sheldon: Dr. Gablehouser.
Dr. Gablehouser: Dr. Cooper.
Howard: Dr. Gablehouser.
Dr. Gablehouser: Mr. Wolowitz

Leslie: Hello men. Sheldon.

Penny: Alright, Sheldon, let's just calm down and we'll call the building manager, he'll come open your door, you just eat your dinner here while you're waiting.
Sheldon: Eat? My dinner? In your apartment?
Penny: Yeah, why not?
Sheldon: Sure, why not? And after the sun's down we can all pile in my pick-up and go skinny-dipping down at the creek. 'cause today's the day to stop making sense.

Leonard: I'm bleeding!
Sheldon: Like a gladiator.

Sheldon: Sheldor, back online.
Penny: What's AFK?
Sheldon: AFK. Away from keyboard.
Penny: Oh, I see.
Sheldon: What does that stand for?
Penny: "Oh, I see"?
Sheldon: Yes, but what does it stand for?
