Amy: Whatever happened to that ape movie you were in?
Penny: Oh, God. Probably nothing. I think I saw the director twirling a sign outside the Verizon store.

Penny: You're building a particle detector using super-fluid helium.
Leonard: You know, when you talk like that, I want to take you right here on this table.
Penny: And you know from past experience, this table can not support both our weight.

Leonard: This is exciting. This is really exciting. I have to go find Sheldon.
Penny: Okay, well, if you find him use the kitchen island. That coffee table will not support both of you.

Sheldon: The whole thing reeks of blueberry. You know I can't stand these scented markers.
Leonard: No one told you to taste them.

Sheldon: I like it. I think you're on to something.
Leonard: Really? You're not messing with me?
Sheldon: Not at all. In fact, I have got something for just such an occasion. I was starting to think I'd never get a chance to give it to you. Good job!
Leonard: You're giving me a sticker?
Sheldon: Not just a sticker. That's a sticker of a kitty saying "Mee-wow".
Leonard: I'm not a preschooler.
Sheldon: Fine, I'll take it back.
Leonard: I earned this. Back off.

Sheldon: Hey, what are you trying to pull? The President of Science isn't in here.
Leonard: You lie down, he'll be here in a minute.
Sheldon: Okay. I thought you were trying to trick me.

Penny: Now you just get comfortable.
Sheldon: No, no. Comfort is the enemy. You know what's comfortable? Slippers, and blankets, and panda bears. Oh, imagine a panda bear with Richard Feynman's face on it!
Warm up the car, Leonard. It's poster time.

Leonard: I know he can be a lot of trouble, but when I see him laying here asleep like this, I just think, how easy it would be to hold a pillow over his face.

Emily: So, I hear you guys have been playing a little game.
Howard: Well, we were just kidding around.
Emily: Well, you may think it's funny that Raj is sweet and sensitive, but I think it's sexy.
*Kisses Raj and pulls a hair out of her mouth*
Emily: Urgh, why is there dog hair in your mouth?

Howard: Okay, so it's one vote Emily, one vote Cinnamon. Penny, you're the tie breaker.
Penny: Say the quote again.
Howard: "It's just so perfect that we're both Libras."
Penny: Wow, this is just so hard. I'm gonna say Cinnamon.
Howard: Yes!
Raj: Come on!

Howard: That was the last one. I promise we won't play it any more.
Raj: Thank you. Because if she ever found out, it would hurt her feelings.
Bernadette: Emily's feelings?
Raj: Yes, Emily!

Raj: Where's Sheldon?
Penny: Date night.
Leonard: That can't be much fun for Amy. You know at work today he tried his first Redbull.
Bernadette: What happened?
Leonard: He chased a squirrel around the quad for a while. And then threw up in my car.

Amy: Sheldon, I want you to take that cap off.
Sheldon: That nagging tone is helping my anxiety. But if you could maybe go 10% less shrill, that would really put the zip-a-dee in my doo-dah.

Sheldon: I knew you'd understand, armadillo Isaac Newton.

Penny: Sheldon, we are just people. We talk about the same things you guys talk about.
Sheldon: You talk about if werewolves can swim? See, Leonard says yes, but I say it depends on whether the human could swim before he was bitten. What do you think?
Penny: Let's just talk about our periods.
