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!

Amy: But enough about Penny, let's talk about us. We're looking good.
Bernadette: We are.
Amy: Better than good. I mean look at you, your body's bangin'.
Bernadette: Amy!
Amy: Don't Amy me. We're always talking about how hot Penny is. Come on, scientist to scientist, how big are those hadron colliders?

Amy: I tried to ask him about it, and he invoked section three, article five of the marriage contract: beeswax, none of your.

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"?

Professor Proton: Oh, great, this again.

Sheldon: Oh, I should probably tell you something about this gift.
Amy: You mean, before you give it to me?
Sheldon: Yes. But may I ask you a question before I give it to you?
Amy: Of course.
Sheldon: Why are we saying give it to you like that?

Sheldon: (3 knocks) Penny! (3 knocks) Penny! (3 knocks) Penny!
Bernadette: What happens if I say come in?
Penny: Well, find out.
Bernadette: Come in!
Sheldon: (silence)
(3 knocks) Bernadette! (3 knocks) Bernadette! (3 knocks) Bernadette!
Penny: Come in!
Sheldon: Keep it up. I've got nowhere else to be.
Bernadette: Just come in.
Sheldon: For future reference, if I want to watch Mean Girls, I'll just stream it on Netflix.
