Leonard: Does this sound familiar? I'd love to go shoe shopping with you. Hiking? It's great. It's two a.m., of course I want to go to Korea Town and sing karaoke with your friends. Who wouldn't?
Penny: Okay, we were going out. You were going to get sex anyway.
Leonard: Really? You would have slept with me after a three-hour documentary on dams?
Penny: No. No woman would.

Leonard: See? Now, that's the great thing. We're out as friends. This is not a date. Sex is off the table. So, let's go learn why hydroelectric power might not be the environmental bargain you think it is. Sorry. Spoiler alert.

Sheldon: This would go a lot faster if you put your trade school diploma to work and helped me set up this high frequency tone generator.
Howard: I have a Masters degree from M.I.T.
Sheldon: Yeah, but you've got a can-do attitude and that's what's important.

Sheldon: Age seven, a blood-thirsty chicken chases me up a tree. Age twelve, a magpie tries to steal the retainer out of my mouth. Age sixteen, a parrot in a pet store called me fat ass. Need I go on?
Raj: Yes, please. This is way better than the movie.

Leonard: Come on, you enjoyed the movie. I saw you tearing up when the village got flooded, and everyone had to relocate.
Penny: No, I was thinking how come they get to leave and I can't.

Leonard: I'm going to get some fries. You want anything?
Penny: Uh, no, thanks.
Leonard: Are you sure? Because you always say no, and then you eat half my fries.
Penny: I just eat the little crispy ones you don't like.
Leonard: No, I love them. I save them for the end, but they're gone because you ate them. And why did I let you eat them?
Penny: To get sex.
Leonard: Exactly.
Penny: All right, I'd like an order of fries.
Leonard: Great. That'll be five dollars. I am having the best time. I'm so glad you suggested we do this.

Leonard: You're going out of your way to talk to that guy because I said we weren't on a date.
Penny: No, I'm talking to him because hes cute.
Leonard: Come on, he's not that cute.
Penny: Yes, he is. With his dorky T-shirt and his little hipster glasses.
Leonard: I wear dorky T-shirts and glasses.
Penny: Yes, but when you're tall and have great cheekbones, you're doing it ironically.

Sheldon: You're biologists. Biology is the study of living things. That's a living thing, get cracking.
Bernadette: I specialize in microorganisms, and Amy studies brains.
Amy: Yeah, neither of us minored in bird-shooing.
Sheldon: Oh, come now. Your undergraduate work must have included a varmints and critters class.

Amy: Sheldon, the only way to get past this fear is to interact with it. Just like you did with the mailman.

Sheldon: Every year tens of people around the world are killed by birds. I'm not going to be another statistic.

Leonard: When you were telling Kevin about your acting career, did you mention your long-running role as Waitress in a local production of The Cheesecake Factory?

Sheldon: It's remarkable. All that time spent in fear. And for what? He's magnificent. Oh, dear. I just realized I haven't offered you a beverage.
Bernadette: Oh, it's just like my grandma with her parrot. And after she lost her marbles with her remote control.

Leonard: Okay. So, we went out, saw a movie, met some nice people, said horrible things about each other in public, all in all, a pretty magical night.
Penny: Okay, I'm not innocent in all this, but you basically called me stupid, you asthmatic dumb ass.

Sheldon: The two of you need to get your women in line!
Leonard: What?
Sheldon: Last night, I was strong armed into an evening of harp music and spooning with an emotional Amy Farrah Fowler. This on a night that I had originally designated for solving the space time geometry in higher spin gravity and building my Lego death star. And why? Because your gal pals, Penny and Bernadette, went out shopping for some wedding nonsense without Amy. An action they took with no thought or regard as to how it would affect me, the future of string theory, or my Lego fun time!
Howard: What do you want us to do about it?
Sheldon: You clearly weren't listening to my topic sentence. Get your women in line! You make them apologize to Amy and set things right. I am a man of science, not someone's snuggle bunny!
Leonard: Why do I have to talk to Penny? She's not my girlfriend.
Sheldon: You invited her to lunch four years ago. Everything about her is on you. You make it so!

Amy: Sheldon, sometimes you forget, I'm a lady. And, with that comes an estrogen- fueled need to page through thick glossy magazines that make me hate my body.
