Sheldon: Good evening, Leonard, Howard, Raj, freeloader.
Howard: So, how'd the lecture go?
Sheldon: In a word, triumphant.
Leonard: Really? Triumphant?
Sheldon: Oh, yes, you should have seen those young people. Thirsty for knowledge, drinking in my wisdom. I may have changed a few lives today.

Amy: Have you considered improving your socialization skills, thus allowing you to communicate more effectively with other people?
Sheldon: Isn't that their burden? I'm the one with something interesting to say.

Amy: Perhaps you should consider taking acting lessons.
Sheldon: Acting lessons. Interesting. It might help if I could act as though I care about my students and whether or not they learn.

Penny: What?
Sheldon: You're an (air quotes) actress, correct?
Penny: I'm not an (air quotes)actress. I'm an actress.
Sheldon: All right. You're an actress. I need you to teach me.
Penny: You want an acting lesson?
Sheldon: Perhaps two. I'd like to master the craft.

Sheldon: So, when could we start?
Penny: Okay, just to be clear. You are asking me for help because I know something that the brilliant Dr. Sheldon Cooper doesn't.
Sheldon: I suppose that's one way to look at it.
Penny: I think it's the only way to look at it.
Sheldon: Are you going to help me or not?
Penny: Probably. I'm just enjoying the foreplay. Does this mean you are done mocking my acting career?
Sheldon: Oh, I'm sorry, I thought making the transition from actor to acting teacher was the signal that one's career had reached the end of the road.

Penny: You were acting?
Sheldon: Yes. In preparation for today's studies, I read Stanislavski's An Actor Prepares, Stella Adler's The Technique of Acting, Uta Hagen's Respect for Acting, and Henry Winkler's Ey!, I'm an Actor.

Sheldon: How shall we begin?
Penny: Well, I thought we'd start with some basic movement exercises. You know, get our bodies warmed up a little.
Sheldon: All right.
Penny: So I just want you to relax and kind of move around in the space. You know, just do whatever feels natural. Sheldon?
Sheldon: (standing still) You said to do whatever feels natural. This feels natural. Certainly more natural than what you're doing.
Penny: Come on, you got to work with me. We need to get connected with our bodies.
Sheldon: Penny, my body and I have a relationship that works best when we maintain a cool, wary distance from each other.

Penny: Okay. Uh, no, the shipment has not arrived, and I really need those shoes. They are my biggest seller. Yes, ladies sizes six through ten. Thank you. Oh, sorry, I have to go, I have a customer. Bye-bye. Hi. Can I help you?
Sheldon: I'd like a frozen yogurt, please.
Penny: Yogurt?
Sheldon: Yeah.
Penny: Um, okay, sure. Luckily, we sell both shoes and yogurt here.
Sheldon: You do?
Penny: Yes. Look up at the sign. And remember, improv is always about saying yes.
Sheldon: All right. Yes. I see a sign. It says Camarillo State Mental Hospital.
Penny: What?
Sheldon: It's the only explanation I can come up with for why you think you sell shoes and yogurt.

Penny: Okay, you know what? Let's just try a different improv. Uh, oh, this time we will be two winos living under a freeway overpass.
Sheldon: Oh, and we're going to use props?
Penny: You bet. I had dreams, you know. I was gonna be famous. Show everybody back home I could be someone. Now look at me. Want some?
Sheldon: You have any frozen yogurt?

Penny: What would you rather do as a scene study?
Sheldon: I'm glad you asked. I took the liberty of adapting a Star Trek fan fiction novella I wrote when I was ten into a one-act play.
Penny: And you think it's better than Tennessee Williams?
Sheldon: Why don't we leave that for future generations to decide?

Sheldon: Very well. I'll set the scene.
Penny: All right.
Sheldon: East Texas. A warm summer night. A woman, Mary, stands on a porch. In the distance, we hear a lonesome train whistle. Woo-woo. The droning buzz of cicadas. Zzzzzzzzz. A coyote howls at the moon, frightening sensitive young boys everywhere. Ow-ow-ow! Out in the woods, an owl screeches.
Penny: Okay, okay. We get it. You set the scene.
Sheldon: Hoot!

Penny: Now just read your mother's line.
Sheldon: Shelly! Shelly, how many times have I told you not to leave your sciencey stuff out on the porch? Goodness, I'll never understand that boy. But then again, I'm a religious nut, and my mind is closed to so many things.
Penny: Woo-woo-woo-woo-woo-woo. Spock to Enterprise. Transport successful.
Sheldon: Glory be to Heaven, some sort of creature just manifested out of thin air. George, put down that Pepsi can full of bourbon that ain't foolin' no one, and get your shotgun!

Sheldon: Oh, Shelly? A man's here to take you away to the future. Be sure to pack clean underwear.
Penny: That's good. That's good. That's good.
Sheldon: Mommy, why are you crying? 'cause I'm gonna miss you, Shelly-bean, even though you creep the bejeezus out of me.
Penny: Okay, I guess we're improvising now.
Sheldon: Well I'm sorry. It's not my fault. I'm just incredibly smart, and everyone around here is dumber than a bag of rocks. Oh, now, don’t you start crying. You get in that spaceship. Mommy's late for Indian bingo.

Penny: (On the phone) Mrs. Cooper, hey, it's Penny. Yeah, I think I broke your son. Hey, hold on. Talk to your mother.
Sheldon: Mommy, I love you. Don't let Spock take me to the future!

Sheldon: Radio contact is sufficient. No need to extend your middle finger.
