Bernadette: We can't all be Cinderella.
Amy: Then how do we decide?
Bernadette: Well, it's simple. This was my idea. I'm driving. I'm Cinderella. You bitches got a problem with that, we could stop the car right now.

Sheldon: (Typing into a search engine) How do I get 12-year-old schoolgirls excited?
Howard and Leonard: No!

Bernadette: Every one of you has the capacity to be anything you want to be.
Penny: Unless you want to be Cinderella.
Bernadette: Come at me. See what happens!

Leonard: So now let's bring out theoretical physicist, Dr, Sheldon Cooper.
Sheldon: Hello, female children. Allow me to inspire you with a story about a great female scientist. Polish-born, French-educated Madame Curie. Co-discover of radioactivity. She was a hero of science until her hair fell out, her vomit and stool became filled with blood, and she was poisoned to death by her own discovery. With a little hard work, I see no reason why that can't also happen to any of you. Are we done? Can we go?

Sheldon: Some people are otters, some people are rocks.

Raj: Anyway I was hoping I could pick your brains a little. I'm supposed to take Lucy out Friday and I need a killer first date.
Amy: Well, evolutionary biology says that women are attractive to a man who is steady in the face of danger, so I recommend an unsafe environment. A seedy bar on the wrong side of the tracks. Picnic near a lunatic asylum. A wine tasting on skid row.

Howard: Last time I was here, I was a scrawny little nerd.
Leonard: And now you're also an astronaut.

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?

Amy: Sheldon, all Snow White needs is one small kiss to wake up.
Sheldon: Heard you the first time.

Howard: Come on. If I was any good at convincing women to do stuff, I wouldn't have spent so much of my 20s in the shower.

Leonard: I never wanted to play the cello. How do you meet girls playing the cello? Hey, you want to come over to my house and listen to me play an instrument that sounds like a suicidal bumblebee?

Sheldon: People should take care of themselves.
Leonard: Oh, like yesterday when you made me drive you to the dry cleaners, the pharmacy and the post office?
Sheldon: I'm not saying people can't use tools. Even an otter picks up a rock when he wants a clam.

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.

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.

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.
