Leonard: We don't have an appointment. And we don't belong here, but we're like crazy big fans. Crazy for Star Wars crazy, not like we have a backpack full of duct tape. Although we do have a backpack that you really don't want to look in.

Sheldon: We want to meet George Lucas and become his friends and play with him.

Sheldon: All right, we have defeated the first challenge. Now we must steel ourselves to face the monster who defends the gate.
Leonard: We're trying to get past a security guard. Not rescue Zelda.

Sheldon: What if I told you that I was the voice of Yoda? A recording session I must attend.

Sheldon: Do you think they're gonna call the police?
Leonard: I don't know. Maybe they'll call Imperial Officers to take us to a holding cell on the Death Star.
Sheldon: I think that's below the pay grade of an Imperial Officer. Storm troopers would really be the ones-
Leonard: Oh, shut up!

Sheldon: And, for all the times you find me irritating, today you got to watch someone shoot me with a taser.
Leonard: That part was pretty good.
Sheldon: See.
Leonard: You did flop around a lot.
Sheldon: I'll take your word for it. I was too busy trying not to defecate.

Sheldon: Are you still mad at me?
Leonard: Yes. We missed our lecture, we were almost arrested, and you got me locked in a room with a man who forced his tongue down the throat of a stuffed Wookiee.

Sheldon: I can see the ranch, Leonard! Oh, it's rustic, it's lovely. I'd take a picture, but people are chasing me. I'm going to make it! I'm going to make it! They have tasers, but they wouldn't dare use-- Aaaaaaah!

Howard: Excuse me. Why is there a sticker on this? It's my TARDIS from Doctor Who. I was planning on moving it in the house.
Bernadette: I think you just answered your own question.

Leonard: I'm a little nervous.
Sheldon: Well, get over it. Confidence is key in these situations.
Leonard: Right. *Pushes button*
Sheldon: You pushed it! Are you out of your mind?

Bernadette: Come on, get in her head. Be intimidating.
Raj: Okay. I'm gonna own you bitch!
Penny: Whoa!
Bernadette: Hey!
Raj: Let's just play.

Sheldon: Leonard, I've been working on an opening joke for our lecture at Berkeley.
Leonard: Oh, I like to laugh. But say it anyway.

Sheldon: What do you say to a graduate of the U.C. Berkeley Physics Department? I'll have fries with that. Because his education hasn't prepared him for a career in the sciences.

Penny: You still worried some Berkeley girl's gonna steal him away?
Amy: Yes. Who do you think gave him the danger whistle?

Sheldon: Would you like to play a physics car game I invented called "I Can't Spy?" It's all the nail-biting tension of I Spy but the added fun of sub-atomic particles and waves outside the visible spectrum.
Leonard: If it's half as much fun as "1 x 10 to the 4th bottles of beer on the wall", I'm in.
