Howard: So this is it?
Amy: Yes. We are using it to map brain wave patterns and then converting them into electrical impulses that can be used to control anything from wheelchairs to robots.
Howard: Based on that ring on your finger, I'd say you're pretty good at controlling robots.
Amy: Careful, that's my fiance you're talking about. And I can program him to hurt you.

Amy: Okay, what is going on?
Penny: We just want you to be prepared for any surprises that could happen tomorrow.
Amy: What surprises?
Bernadette: We don't want to spoil anything, but you should know that Sheldon said he's ready to be physical.
Amy: You shut your damn mouth! You actually heard him say this?
Penny: Yes, he said he wants to do something to show you how much you mean to him.
Amy: I can't believe it. I don't know what to say.
Bernadette: Well, we're really happy for you and we know how much-
Amy: I do know what to say. Let's get me waxed!

Sheldon: Sheldon Cooper does not get lucky.
Amy: You and me both, brother.

Amy: Do you have any idea how hard it is to laugh at a knock knock joke that starts "Knock Knock Knock, Amy. Knock Knock Knock, Amy. Knock Knock Knock, Amy"?

Penny: No, I've been reading Bernadette's parenting book. It's like the answer key to the Sheldon test.

Leonard: It's fine, I've been driving him for years. What's one more day?
Sheldon: Oh, and I've got a new car game we can play. It's called "What siren am I?"

Sheldon: All right, you ready for your next one? Just a warning, this one's a little annoying. (imitates a high-pitched siren)
Leonard: Let's take a little little break, I'm getting a headache.
Sheldon: Aw, right in the middle of our fun game.
Leonard: Yeah, weird.
