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.

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.

Amy: Why'd you pop it?
Sheldon: Sorry, I was aiming for your heart.

Amy: Look, your anxiety levels are right in the zone.
Sheldon: Really? Oh, that's fantastic. No wait, they're dropping. Why are they dropping?
Amy: Because you're happy they're elevated.
Sheldon: Oh, that is infuriating. Oh look, they're going back up again. Terrific. Oh no, they're going back down.

Raj: You know what, I think it's a little weird that you remember me saying all these things. Maybe the truth is you're jealous of all my relationships.
Howard: Oh. Maybe I am. Who wouldn't want to the girl - or possibly dog - to hear the words "You're so lucky. You have the shiniest hair."
Leonard: That is a tough one. I know he brushes both of them.

Penny: So, whichever rep has the best sales for the quarter gets a trip for two to Hawaii.
Amy: That would be so romantic for you and Leonard.
Penny: Yeah, clearly you haven't seen him on the beach walking around with his metal detector.

Sheldon: Ladies.
Penny: What's up?
Sheldon: As you may know, I have been experimenting with elevated anxiety levels, and I thought what better way to increase my discomfort than to subject myself to an evening of tasteless, uncensored crotch talk.

Howard: Okay, who was he talking to Emily or Cinnamon? "I want you to know the bed feels so lonely when you're not in it"?
Raj: Yeah, I might not be liking this game so much.
Leonard: Cinnamon. Give me another one.

Howard: Okay, "Check it out. I got us matching sweaters."
Leonard: We all got the Christmas card. Cinnamon.

Raj: You know a man can care deeply about a woman and a pet. It's not strange.
Leonard: Ooh, Emily. I heard him say that to Emily.

Sheldon: I don't want to tell you how to do your job, but when a mouse completes a maze, it gets a food pellet.
Amy: It also gets its brain plucked out with tweezers.
Sheldon: And its last meal was a food pellet? You're a monster.

Sheldon: I'd like to ask you all to do something for me. Keep me on my toes. Just throw me off my game. Essentially, go out of your way to make my life miserable.
Howard: Hold on. What's in it for us?
Sheldon: Well, I suppose-
Howard: Okay, we'll do it!

Sheldon: You sounded in distress. I was worried something unpleasant was happening to you, like a murder or spontaneous coitus with Leonard.
