Penny: Oh, it's Leonard. He says Sheldon's drunk and they're gonna do karaoke if we want to join them.
Penny: That sounds fun.
Amy: Oh, no. Sheldon's drunk texting me.
Bernadette: What's it say?
Amy: "Would you like to sing karaoke with us."
Bernadette: How is that a drunk text?
Amy: He used a period instead of a question mark. He's so wasted.

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.

Howard: I love you. And I'm not just saying that because your breasts are gonna get bigger.

Sheldon: You're kidding! What kind of maniacs have coitus in someone else's bedroom?!
Howard: Thank you, Pasadena! Good night!

Raj: Look at that. You've known you're gonna be a father for less than a day and you're already stepping up.
Leonard: I'm telling you, you got this.
Howard: Maybe you're right.
Sheldon: Of course he's right. You and I both know how hard it is growing up without a father. That's why I'm confident you're gonna be the best dad you can be.
Howard: Thank you, Sheldon.
Sheldon: You're welcome. And if he has twins, we can do all kinds of neat experiments on them.
