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: Hey, check it out. That looks like the moped you used to have.
Howard: It wasn't a moped. It was a scooter.
Raj: How's that better?
Howard: You do not want to walk into a scooter bar and ask that question.

Sheldon: Amy. Thank goodness you're home. I don't know if you can tell, but I am literally losing my mind.
Amy: You are?
Sheldon: Isn't it obvious? I just used "literally" figuratively. Like a crazy person.
