Leonard: OK, is everyone clear on the plan?
Howard: Yes, Koothrappali's going to wet himself, I'm gonna throw up, Sheldon's gonna run away and you're going to die. Shall we synchronize our watches?

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.

Leonard: Sheldon, would you be prepared on a non-presidential basis, to create an emergency ad-hoc slurpee/icee equivalency?
Sheldon: Oh Leonard, you know I can't do that.

Penny: What are you saying? That I'm using my body to get dinner? That I'm some sort of Chinese food prostitute?

Raj: If anyone cares, I still have to pee.

Leonard: Come on, there's four of us and one of him.
Sheldon: Which means his triumph will be even larger. Minstrels will write songs about him.

Kurt: Where's your back up?
Leonard: I don't need back up, I have right on my side ... and I'm wearing cargo shorts under my pants.

Howard: Maybe we should have your head notarized.

Sheldon: My expenses account for 46.9% of my after-tax income. The rest is divvied up between a small savings account, this deceptive container of peanut brittle, and the hollowed-out buttocks of a superhero action figure who shall remain nameless for his own protection. Or her own protection.

Penny: I'll pay you back as soon as I can.
Sheldon: Of course you will. It's impossible to pay me back sooner than you can. Assuming you subscribe to a linear understanding of time and causality.

Penny: Well, remember Kurt?
Leonard: Your ex-boyfriend?
Penny: Yeah. He got arrested for taking a whiz on a cop car.
Leonard: What?
Penny: He was drunk.
Leonard: I would hope so.

Penny: No, I can't. Sheldon, honey, I don't want things to be weird between us.
Sheldon: Won't it also be 'weird' if I have to say hello to you every morning on my way to work and you're living in a refrigerator box and washing your hair with rainwater?

Howard: Ugh. This mu-shu pork is burning a hole through me duodenum.
Raj: Leviticus 11:3 "Only that which parteth the hoof and cheweth the cud among the beasts shall ye at."
Howard: Hey, do I mock you with the Bhagavad-Gita every time you scarf down a whopper?

Penny: The building manager's showing an apartment downstairs, and I haven't paid my rent.
Sheldon: Oh, I see. Penny, I'm not sure I'm comfortable harboring a fugitive from the 2311 North Los Robles Corporation.

Penny: Wow, you got a lot of money in there.
Sheldon: That's why it's guarded by snakes.
