Oh, hey! Did you see that? I figured out how to open my door all by myself. Maybe I'll fling some feces around my cage to celebrate.

Penny

Nathan Fillion: Oh, umm. I think you made a mistake. I'm not an actor.
Raj: Don't say that. You're not Dame Judi Dench but you're pretty great.

Raj: The guy who plays Jon Snow was a jerk and we still watch Game of Thrones.
Leonard: He was a jerk because you rear-ended him.
Raj: I was distracted. It's weird seeing a member of the Night's Watch with kayak strapped to his car.

Are you folding that like a crazy person to get me to do it?

Sheldon

Sheldon: Gee, Penny. Life's given me lemons, what should I do?
Penny: You could shove them somewhere.
Sheldon: Okay, now you're getting creative.

Sheldon: How many Edisons does it take to screw in a light bulb?
Amy: How many?
Sheldon: Who cares he stole the idea and doesn't deserve his own joke.

Amy: Okay, that's enough.
Penny: What? No! I really want to know what happens-- and Bernadette really, really, really wants to know what happens.

Penny reading Amy's book: "Amelia stood before the newly repaired time machine.She regretted giving Cooper the part he needed."
Bernadette: Because she wanted him to give her the part she needed.

Leonard: Stephen Hawking liked our paper. Said the premise is intriguing.
Sheldon: Good to see you again, Mr. Stephen-Hawking- Liked-Our-Paper.
Leonard: And you as well, Mr. Our-Premise-Is-Intriguing.
Howard: How do you do, Mr. I'll- Admit-That's-Pretty-Cool?
Raj: Yeah, you keep setting me up for failure.

Sheldon: Professor Hawking?
Professor Hawking: Oh, brother, you should see the look on your faces.
Leonard: You really didn't like our paper?
Professor Hawking: I like your paper very much. The premise is intriguing.
Sheldon: Then why are you attacking us?
Professor Hawking: If you were sitting in a chair for 40 years, you'd get bored, too. Anyway, got to go. I promised to help the neighbor kid with his math homework. Ciao.

Penny: You look like a talking cupcake!
Pageant Bernadette: And you should pick me for Miss California Quiznos 1999, because I want to...Tell you what I want, what I really really want I'll tell you what I want, what I really really want I wanna, I wanna, I wanna, I wanna Really, really, really be Miss California Quiznos 1999!

You mess with the bull, you get the horns. I'm about to show this guy just how horny I can be.

Sheldon

TBBT Quotes

Raj: Well, to paraphrase Shakespeare: It's better to have loved and lost than to stay home every night and download increasingly shameful pornography.
Penny: Oh... you poor baby.
Raj: What's wrong with me, Penny?
Penny: Nothing, nothing. You know, if we weren't friends - and you hadn't brought up that creepy pornography story - I'd be on you like the speed of light squared on matter to make energy.
Raj: Hey, you totally got that right. E = MC squared.
Penny: I listen. I have no idea what it means, but I listen.

Sheldon: I recently read that during World War Two, Joseph Stalin had a research program to create supersoldiers by having women impregnated by gorillas.
Howard: What a sick use of science.
Raj: Hey, as long as the baby's healthy.
Amy: I wonder if Stalin considered any other animals.
Leonard: Hippos are the deadliest creature. A half-human, half-hippo soldier would be pretty badass.
Howard: Yes, but when they're hungry-hungry, you can stop them with marbles.
Sheldon: Yeah, the correct animal for interspecies supersolider is koala. You would wind up with an army so cute it couldn't be attacked.
