Sheldon: You know, I'm really happy with our wedding date. The month squared equals the square of the sum of the members of the set of prime factors of the day. Isn't that romantic?
Amy: Yes, it's like that Shakespeare sonnet, "Shall I compare thee to a day that's also a really weird math problem."

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.

Leonard: Do you guys have a location yet? 'Cause you don't have a lot of time.
Amy: Hey, it took us nine months to pick a date, and a week to decide if brains can have lips on them, so get in the boat and row.

Leonard: Uh, so, look, I'm here to ask you to give Sheldon and Amy the Athenaeum for their wedding.
Barry Kripke: (laughs) Why would I do that?
Leonard: Because deep down, Barry, you're a really good guy.
Barry Kripke: But am I?

Howard: Honestly, it's gonna be hard when we both go back to work. I've been thinking maybe it would be better if one of us decided to stay home.
Raj: I don't know, I was raised by servants, and look at me.
Howard: I literally can't tell if you think that's good or bad.
