Amy: All canines instinctively know how to swim. Why wouldn't a werewolf have the same abilities?
Bernadette: Well, they're not a hundred percent wolf. They're a werewolf, that's only a part wolf. That's like comparing apples to oranges.
Sheldon: Thank you! Although technically it's apples that turn into were-oranges when the moon is full.

Oh, this is fun. We should do it sometime when you aren't all PMSing.

Leonard: What is going on?
Sheldon: Oh, I need to keep my anxiety at the right level. So I'm using Darth Vader, the Joker and Godzilla's roar to keep me in that sweet spot. I tried including Taylor Swift in the mix, but turns out I love her.

Leonard: At least listen to it through headphones. I'm trying to sleep, good night.
Sheldon: Boy. Taylor was right. Haters gonna hate, hate, hate, hate, hate.

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.

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?

Sheldon: No, I don't want to go to sleep. You can't make me.
Penny: You're right, we can't.
Sheldon: Yeah, darn straight, you can't. Try to tell a grown man to go to sleep.
Penny: [sings] Soft kitty, warm kitty.
Leonard: [sings] Little ball of fur.
Sheldon: That's not gonna work.
Penny: Happy kitty, sleepy kitty.
Leonard & Penny: Purr, purr, purr.

Penny: We watch movies with director's commentary.
Amy: Oh, my favorite. George Lucas can talk through the entire movie but I say one word and I'm banished to the kitchen.

Penny: Ooh, we could go horseback riding.
Amy: I actually can't. My hips don't open wider than 22 degrees. I rode a very thin pony once. On the first bump I just popped right off.
