Leonard: So, Amy, what's going on with your addiction study?
Amy: Sadly, I'm no longer associated wtih that project.
Leonard: Why? What happened.
Amy: Typical bureaucratic nonsense. You can get animals addicted to a harmful substance, you can dissect their brains, but you throw their own faeces back at them and suddenly you're unprofessional.

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!

Sheldon: Sheldon Cooper does not get lucky.
Amy: You and me both, brother.

Amy: I guess it must have been back when I was in the Girl Sprouts.
Bernadette: Girl Sprouts?
Amy: My mom made it up as an alternative to the Girl Scouts. She didn't want me selling cookies on some street corner like a whore.

Sheldon: She's remarkable.
Leonard: She really is.
Sheldon: How is it that she can remember all those lines, yet as a waitress she can't remember no tomato on my hamburger?

Bernadette: It smells pretty ripe in here. You kinda feel it in your eyes.

Lucy: I'm kind of broken.
Raj: That's great. I'm broken, too.
Lucy: Oh, no you're not.
Raj: Oh, I totally am. If it wasn't for this beer, I couldn't even talk to you right now. I'm a wreck. There are many things seriously wrong with me. And not quirks, either. Like diagnosable psychological problems. Maybe brain damage.
Lucy: Well how do I know you're not just saying that?
Raj: Go out with me on one date. I promise you, you'll see.
