Amy: Look, when you wanted Penny, you didn't care what anybody else thought or wanted, including Penny.
Leonard: That's true. Yeah, yeah, there was something I wanted, I went after it and I got it.
Amy: Now you're hiding from it on the stairs, so it all worked out.

Anu: What's that smell?
Raj: Uh, everyone has their own theory. Dr. Tibourgh thinks it's mold. I think it's Dr. Tibourgh.

Penny: I mean, come on, when was the last time you did something totally selfish without worrying about what anyone else wanted?
Leonard: Uh, according to my mother, I took my sweet time being born.
Penny: How is that selfish?
Leonard: Apparently, she had dinner reservations.

Amy: It's fine. We'll have barbecue.
Sheldon: Oh, of course. I'm nothing if not flexible. I'm sure that at some point in the 3,000-year history of the Chinese empire, a cavalryman crossing the Gobi Desert was forced by hunger to eat his own horse and roast it over a campfire, hence, Chinese barbecue.

Sheldon: [inner monologue] Hmm, this is nice. It's sort of like floating in space. But better because my eyeballs haven't frozen.

Howard: Hey. You still mad?
Bernadette: Are you still a jackass?

Howard: Are your eyes closed?
Raj: Yes. What is it? Show me.
Howard: Okay, open them.
Raj: You bought me a scooter?! No, I bought me a scooter!
Raj: Then why did you make me close my eyes?
Howard: I wanted to see the expression on your face when you saw how happy I was.

Amy: So apparently, if we win, I'll be the fourth woman ever to win a Nobel in physics.
Penny: Wow, that's a big deal.
Amy: Yeah, tell me about it. This morning, I blew through my antiperspirant in, like, an hour.

Raj: Hey, I forget, why did you sell the scooter?
Howard: I finally got my woman. Then my woman made me sell it.

Ms. Davis: President Siebert, would you like to start?
President Siebert: [clears throat] This is all my fault. I assumed you knew the Nobel Prize was good and we wanted to win it, so that's on me.

Ms. Davis: Thank you both for coming. President Siebert asked that I be a part of this conversation to help us calmly discuss what went wrong and how we can better move forward. We are not here to point fingers, so, Dr. Cooper, please stop that.

Ms. Davis: Well, how about have a seat? Maybe you'd like a glass of water?
Amy: You have anything with a little more kick?
Ms. Davis: Seriously, Dr. Fowler, this is human resources.
Amy: You're right. I don't know what I was thinking.
Ms. Davis: [retrieves two glasses and a bottle of whiskey] You want ice, you're out of luck.

Amy: What do you say? We could both use a break. Come on, I'll do it with you.
Sheldon: Okay, but not in the same tank. I already shared a uterus with my twin sister. I don't need to go through that again.

Sheldon: Hang on.
Amy: What-what are you doing?
Sheldon: I'm googling what to do when someone's freaking out. Huh. Uh, whoa, it says here that a walk can be calming. Bye.

Sheldon: I tried to console her, but nothing seemed to work.
Leonard: Okay, when you say you consoled her, what exactly does that mean?
Sheldon: [sighs] I took a walk, I came back, she was still upset, so I came here.
Penny: Well, I don't see what else you could've done.
