Penny: I use to cut my brother's hair. I could do it for you
Sheldon: I know you mean well, offering the skills of the hill folk, but here in town we don't churn our own butter, we don't make dresses from gunny sacks, and sure-as-shootin don't get our hair cut by bottle blon..
Leonard: Sheldon be nice!
Amy: I'll let you in on a little secret. Originally, we were painted nude. But I had him add clothes cause I thought it was an unnecessary challenge to our heterosexuality.
Penny: Yeah, good call.
Amy: But, if you ever change your mind, all it would take is some warm, soapy water and a couple of sponges.
Penny: You're talking about the painting, right?
Amy: Goodnight, Painting Penny. Goodnight, Real Penny.
Penny: Goodnight, Real Amy.
Amy: You don't have to say goodnight to Painting Amy, because she's never leaving. Bernadette: Goodnight, Real Penny. Goodnight, Transvestite Penny.
Penny: It's kind of heavy
Bernadette: Too bad you're not as strong as the dude in the painting.
All right, Howard Wolowitz, listen up. You sign anything she puts in front of you, because you are the luckiest man alive. If you let her go, there is no way you can ever find someone else -- speaking on behalf of all women, it is not going to happen; we had a meeting.
Penny: So you're saying if I became a famous movie star, we got married, you wouldn't sign a pre-nup?
Leonard: Absolutely not! If I'm gonna be stuck at home with the kids while you're on location cheating on me with Ryan Gosling ... then Leonard gots to get paid.
You know I'm a big believer in breaking bad news to a guy when you're in bed with him. That's how I told my high school boyfriend I slept with his brother. That's how I told his brother the same thing.
Berndette: Oh, I don't know. I don't want to manipulate him with sex.
Penny: Oh, sweetie ... that's what sex is for.
Sheldon, that's not what girlfriends are for. Although, you don't use them for what they're for, so what do I know?
Howard: I got pretty exciting NASA news today. Next week I fly to Houston for orientation and zero-gravity elimination drills.
Penny: What does that mean?
Bernadette: He's gonna to learn to poop in space.
Howard: Open the pod bay doors, HAL.
Raj: Maybe your nickname should be "Brown Dynamite."
Leonard: So, I've got a gunshot wound. That's pretty bad-ass.
Penny: No, you've got a Reebok with a gunshot wound and an ouchie on your pinky toe.
Penny: You mean like a beta test?
Leonard: Well, technically, this would be an alpha test. A beta test requires people that weren't involved in the development of the appli....
Penny: Seriously, do I not get credit for knowing beta test?
Leonard: No, absolutely you should.
