Penny: Wait. What's wrong with geology?
Sheldon: Let me put this in a way you'll understand, Penny. You remember how you explained to me that the Kardashians aren't real celebrities? Well, geology is the Kardashians of science.

Penny: I gave him a new look. It's cute, huh?
Amy: Yeah, it's cute. That's the problem. I don't need other girls to see him walking around like sex on a stick.
Sheldon: She's right. I'm too hot.

Howard: I hope I get to meet her as soon as possible.
Raj: Why the rush? She isn't going anywhere.
Howard: She is. But I like that attitude.

Sheldon: Am I wasting my life on a theory that can never be proven?
Howard: Maybe. But how great is Game of Thrones?

Raj: I know. Being an astrophysicist right now is like being a rock star.
Howard: Only without the sex.
Raj: Yeah, literally, none of it.

Amy: Y-You'll feel better after you eat.
Sheldon: Okay.
Amy: What-what do you want, like, Thai food? A... a burger?
Sheldon: I don't know!

Emily: How serious were you two?
Raj: Well, to be honest, we only went on four dates, hugged twice, kissed once, and there was a handshake loaded with sexual innuendo.
Emily: Wait, so... a girl you never slept with sent you an e-mail and you felt so guilty about it that you had to tell me?
Raj: Yeah.
Emily: That's kind of adorable.

That was Wil -- he's feeling a lot better. Apparently, he's 12-down in the TV Guide crossword puzzle.

Leonard

Sheldon: Quick poll: PS4 or Xbox One? Raj.
Raj: Uh, Xbox One.
Sheldon: Penny.
Penny: Huh?
Sheldon: Leonard.
Leonard: PS4.
Sheldon: Wolowitz.
Howard: Both great.
Sheldon: Bernadette.
Bernadette: I like the Wii.
Sheldon: Thanks, Grandma

Penny: Okay, look, here, page 58. I oil-wrestle an orangutan
in a bikini.
Leonard: Just to clarify, which one of you is wearing the bikini?
Penny: Both of us.
Leonard: So it's a family film.

Penny: Next time I get pulled over for a speeding ticket, here come the waterworks.
Sheldon [running to bathroom]: Here come the waterworks!
Leonard: Aren't you gonna ask?
Penny: What is this, my first day?

Sheldon: Boy, do I have to urinate.
Leonard: If only there were a solution
to that.
Sheldon: Seriously. I feel like I've got
a fish tank in my pelvis.

TBBT Quotes

Sheldon: There are post-prom mating rituals?
Penny: Not always. Unless your date drives a van with an air mattress, then always.
Sheldon: Well, if it's part of the prom experience, then I'm open to it.
Penny: You're kidding.
Sheldon: I may be an alien, but I have urges.If Amy wants to copulate by firing her eggs into space, well, then, I will happily catch them with the reproductive sac on my upper flermin. I'm not the best at reading facial cues, but I can see that you're a little turned on.

Penny: Hey, Sheldon, did you change your Wi-Fi password again?
Sheldon: Yes, it's "Penny, get your own Wi-Fi." No spaces.
