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: Hold on. You're getting married and you didn't invite me?
Penny: It was kind of a spur of the moment thing.
Amy: Wow. Hope I can catch the bouquet from here.

Penny: So you have a song stuck in your head. It happens to everybody.
Sheldon: Well, I'm not everybody. I have an eidetic memory. I should be able to remember what song this is, but I can't. Something's wrong with me.
Penny: I told you if we were patient, he'd figure it out for himself.

Professor Proton: Oh, great, this again.

Bernadette: So, you're really going out with Dave again?
Amy: Why not? He's actually a very nice guy.
Bernadette: But he spent an entire date talking about how much he loves Sheldon.
Amy: That's nothing Sheldon hasn't done before.

Sheldon: I remember the song! It's called "Darlin'" by the Beach Boys! Oh, thank goodness! I'm not crazy! I don't have to take a pigeon as my bride!
Leonard: There goes our shot at him living on the roof.

Penny: So what's going on?
Sheldon: I don't know. I looked around the room, and I saw all the faces and the presents, and it it was just too much.
Penny: I get that. Hey, you want to just bring a few people in here? You know, Wil Wheaton in the bathtub, Batman on the toilet. It'll be like the weirdest Comic-Con ever.

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.

Penny: What are you doing back?
Leonard: We got a flat and couldn't get the tire off.
Penny: Oh, I'm sorry.
Leonard: Thank you.
Penny: If it makes you feel any better, I pierced Amy's ears and her mom made her sit in my closet.
Sheldon: We blew up Feynman's van.
Penny: My dad killed my pig with his tractor.
Leonard: I spent the night in Mexico with Sheldon.
Penny: You win.

Professor Proton: Why isn't it ever Angie Dickinson's bedroom?

Amy: Hi, Sheldon.
Sheldon: Hello.
Amy: Are you feeling any better?
Sheldon: Physically, yes, but I'm upset because everyone's mad at me for no good reason.
Amy: Why don't you tell me what happened, and in a gentle, loving way, I'll explain to you why you're wrong.

Stuart: Anyone else need anything before I go?
Howard: I'll give you a dollar if you make fun of Raj.
Stuart: That's mean.
Howard: Five.
Stuart: You look like Tigger if Tigger looked like a jackass.
Howard: Uh, if you ever need a reference or anything, just let me know.

Sheldon: Then it's settled. Amy's birthday present will be my genitals.

Penny: Well, she did soften your life, didn't she?
Sheldon: Yes! She's like the dryer sheets of my heart!
