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

Amy: [inner monologue] Wow, this is really dark. There's no difference between my eyes being open or closed. Open, closed. Open, clo- Nope, same thing.

Sheldon: [inner monologue] Look all the infinite Mandelbrot sets. Here a brot, there a brot, everywhere a Mandelbrot.

Amy: That's great. I'm so happy for you.
Sheldon: Uh, yeah, a little constructive criticism: You're saying you're happy, but you're using your mean voice.
Amy: Thanks for pointing that out. Now you got it.

Amy: Sheldon, I'm freaking out.
Sheldon: Well, is this still about the Nobel Prize?
Amy: Yes, it's about the Nobel Prize!
Sheldon: And back to the mean voice.

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.

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

Bernadette: What if you fell? What if you got hurt? I don't want to raise two small children and one large vegetable.

Bernadette: You know what? I'm done talking about this. Do whatever you want.
Howard: I will!
Bernadette: I just want you to ask yourself if that tiny, ridiculous scooter is the hill you want to die on.

Sheldon: You know, I know she's unhappy, but I don't know how to help.
Leonard: Maybe you can't. Sometimes people are upset, and all you can do is be there for them.
Sheldon: And while I'm there, what do I do?
Leonard: Nothing.
Sheldon: Oh, so like what you're doing right now to help me.
Leonard: You're up.

Penny: Sheldon, maybe you don't know what to do because Amy's always taking care of you.
Sheldon: Of course. And by calming down, I've taken away the one thing that gives her comfort: caring for me.
Penny: That's what you heard?
Sheldon: Yes. I need to have an emotional meltdown so she's forced to focus on me and forget about herself.
Leonard: No. Th-That's not even close to what-- Uh, you know, actually, that might be your best move.

Amy: Sheldon, whatever you're doing, I-I don't have time for it right now.
Sheldon: I'm sorry. I know you're upset, but I don't know how to make it better.
Amy: I don't know how you can, either. I mean, I don't know if anybody can. I just-- I feel like I'm letting everybody down.
Sheldon: I'm about to hold you. Would you like to smell my hand first?
Amy: I'm fine.

Howard: On a positive note, the scooter helped Bert meet a girl.
Bernadette: Oh, that's nice. What does she do?
Howard: She's an E.R. nurse.
Bernadette: Oh, no.
Howard: No. It was a real meet-cute. She popped his arm back in the socket, and when he came to, they exchanged phone numbers.

Amy: Ms. Davis?
Ms. Davis: Dr. Fowler, how can I help you?
Amy: You were right about this Nobel Prize being bigger than I am, and you were right that, like it or not, I am a role model. But you are wrong to keep me on the sidelines. I am smart, I'm capable, and I can make a difference.
Ms. Davis: Well said. You make a strong case.
Amy: Damn right, 'cause I'm a strong woman wearing a strong man's deodorant!

Raj: You guys know that Hemingway had cats with six toes?
Penny: Six toes per foot or six toes total?
