Leonard: Guys, please don't make this a school project where I'm the smartest kid doing all the work while the slackers sit back and watch.
Sheldon: We're not. This time you're the smart kid doing all the work while the even smarter kids sit back and watch.
Howard: So, you think I'm one of the smarter kids?
Sheldon: No, you're a tool I was using to make my point.

Bert: (To Lucy, after speaking to Raj) You can do better!

Girl: So you just flew around? That's kind of like my uncle. He's a flight attendant.
Howard: No, I'm an American hero. Your uncle brings people nuts, okay?

Leonard: I'm thinking one way to counter bias in the peer-review process is for papers to be submitted under gender-neutral names. Like S. Smith instead of Samantha Smith.
Sheldon: I supposed there is a history for professional women using their initials so as not to be pre-judged. Harry Potter's J.K. Rowling, Star Trek's D.C. Fontana.
Howard: Van Nuys pole dancer D.D. Melons.

Raj: Thanks again for letting me crash girls' night.
Penny: Are you kidding? You brought fancy wine and made fondue. I've slept with guys for less.
It's a joke. Based on real events.

Sheldon: I believe in a gender blind society like in Star Trek. Where women and men of all races and creeds worked side-by-side as equals.
Leonard: You mean where they were advanced enough to develop an interstellar warp drive, but a black lady still answered the space phone?

Penny: Let's try it again, and maybe this time, you could work on your body language a bit. You know, when you're all hunched like that, you're shutting the audience out, but when you're relaxed and open, you're inviting them in.
Sheldon: Right. And which one do I want?

Howard: Raj is a proud, passionate man. If you go running out on him again, you're only gonna get like three of four more chances before you are history.

Raj: I guess you could say Raj is my name and stars are my game.

Sheldon: What's wrong?
Penny: I just think it might look more natural if you talked to me instead of the camera. You know, like a real conversation. It's something we work on in my acting class.
Sheldon: Interesting. A few people in the comments section have said that my delivery is robotic. Perhaps that's not the compliment it sounds like.

Howard: He's upset because he can't get anywhere with women.
Sheldon: Would it help if I gave him some pointers?
I'm just funnin' ya.

Sheldon: She's remarkable.
Leonard: She really is.
Sheldon: How is it that she can remember all those lines, yet as a waitress she can't remember no tomato on my hamburger?

Lucy: I'm kind of broken.
Raj: That's great. I'm broken, too.
Lucy: Oh, no you're not.
Raj: Oh, I totally am. If it wasn't for this beer, I couldn't even talk to you right now. I'm a wreck. There are many things seriously wrong with me. And not quirks, either. Like diagnosable psychological problems. Maybe brain damage.
Lucy: Well how do I know you're not just saying that?
Raj: Go out with me on one date. I promise you, you'll see.

Howard: Come on, we could have a pants party! Go put some on!

Bernadette: It smells pretty ripe in here. You kinda feel it in your eyes.
