Leonard: Sorry.
Amy: So, are you off to dinner with Priya, Howard and Bernadette?
Leonard: Yeah. How did you know?
Amy: I heard it at the mall, when I was shopping with my girlfriends, 'cause, you know, that's kind of my life now. Have a good night. Try not to ogle my caboose as I walk away.

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: 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"?

Raj: She didn't even get to see my penis.

Penny: I'm sorry, shoes, but you have to go back.
Shoebox (Penny): But, Penny, we love you.
Penny: I love you, too, but you cost more than my rent.
Shoebox (Penny): But Penny, you look so good in us.
Penny: (To Amy) Damn it, the shoes are right!

Sheldon: Red is angry, yellow is frightened, green is jealous and blue is depressed. Perhaps we can assign a color to lonely.
Raj: Nothing rhymes with orange. Its probably lonely.
Sheldon: All right. Come in. You look positively orange with loneliness. No, I dont see that catching on at all.
