Leslie: So, Sheldon, I see you're organizing papers for the Smithsonian Museum of Dumbassery.
Ramona: There won't be any room until they get rid of the permanent Leslie Winkle exhibit.
Sheldon: Oh, good one.

Ramona: Dr. Cooper, I have to tell you, your friends are holding you back.
Sheldon: I prefer to think of it as I'm pulling them forward.

Howard: Hello, boys.
Leonard: Ahoy, matey.
Howard: Noticed the eye patch, did you? It's all part of a technique I've been studying for picking up women. You employ a visual display designed to make yourself distinctive and memorable.
Sheldon: Oh yes, like the male peacock with brilliant plumage or the rutting baboon with engorged hindquarters.
Leonard: Or in this case, the bar mitzvah boy with pinkeye.

Sheldon: What happened?
Leonard: Howard's at the Mars Rover lab. He says he's in trouble. DEFCON 5.
Sheldon: DEFCON 5? Well, there's no need to rush.
Leonard: What?
Sheldon: DEFCON 5 means no danger. DEFCON 1 is a crisis.

Sheldon: You brought a girl to the Mars Rover control room?
Howard: Yeah, I picked her up in the bar. She's a doctor. One free barium enema and my mother won't care she's not Jewish.
Leonard: Wait a minute, so the eye patch and the insults worked?
Howard: No, there were three other guys with eye patches, it was a fiasco. What did work was, "How'd you like to visit a secret government facility?"

Sheldon: So what exactly do you want us to do?
Howard: I need you and Raj to help me get the Rover out of the ditch, and I need you to get Stephanie out before somebody notices she's here. She doesn't exactly have clearance.
Sheldon: Really? They don't let strange women from honky-tonks come in and play with $200million government projects on distant planets?

Stephanie: So are you a scientist like Howard?
Leonard: No one's a scientist like Howard.

Howard: My mother is so gonna love her.
Sheldon: Oh, how nice. Maybe they can carpool when they visit you in federal prison.

Stephanie: (Breaking away from kissing) I'm sorry. I totally interrupted you. What, what, what were you saying?
Leonard: Just said Howard's a terrific guy. He's got a great sense of humor, he loves his mother, a lot, some people say too much.
Stephanie: I really like that you're such a loyal friend.
Leonard: Yeah, I am loyal. You know, if you look at the big picture.

Howard: OK, I guess we have to turn to Plan B.
Raj: What's Plan B?
Howard: Erase all the hard drives, scrap the surveillance tapes, wipe our fingerprints off every surface and run.
Sheldon: Why wasn't that Plan A?

Penny: Howard, didn't you say you worked on the Mars Rover?
Howard: No, you're mistaken.
Penny: Yeah, when we first met, you said that if I went out with you, I could drive a car on Mars.
Howard: I don't know what you're talking about.

Sheldon: Will you all excuse me? Leonard is subtly signaling that he'd like to talk to me in private.

Penny: Yeah, I remember specifically. You started by asking if I was from Mars because my ass was out of this world.
Howard: Well, that does sound like me, but no.

Sheldon: Is there some problem?
Leonard: Yeah. Listen, I have to kinda sneak out for a while.
Sheldon: All right, goodbye.
Leonard: No, wait. If anyone asks you where I went, you don't know.
Sheldon: Where are you going?
Leonard: I can't tell you that.
Sheldon: Who would ask me?
Leonard: I can't tell you that, either.
Sheldon: So you brought me in here to inform me that you can't tell me where you're going and you can't tell me who might ask?
Leonard: Yeah, I really didn't think this through.

Sheldon: If someone, and of course, we don't know who this would be, does ask where you've gone, what should I say?
Leonard: I don't know. Just tell them I went to the office.
Sheldon: Are you going to the office?
Leonard: No.
Sheldon: Then how can I say it convincingly?
Leonard: Just say, Leonard went to the office.
Sheldon: All right. Leonard went to (dramatically) the office.
Leonard: What is? No, not like that! Just, Leonard went to the office.
