Amy: So are you feeling okay? No wedding jitters?
Sheldon: No. There is nothing in the world that would stop me from marrying you tomorrow, even me from the future coming back to prevent the wedding and the subsequent birth of a child who will destroy humanity.
Amy: Because if you came from the future, that would mean you already went through with the wedding because you believe that time travel is on a closed loop.
Sheldon: I love you so damn much.

Sheldon: I'd like to take a moment to personally thank Dr. Amy Farrah Fowler, who you may or may not know is the first woman to co-host a flag or banner related Internet infotainment show.
Amy: Take that glass ceiling!

Sheldon: *knocks three times* Amy, Bernadette, Penny. *repeats three times*
Bernadette: He's never going to stop doing that, is he?
Amy: I don't mind. I'm hoping to put his love of repetition to good use someday.

Penny: You look beautiful.
Amy: Of course I do, I'm a princess and this is my tiara!

Penny: If you guys were hungry, why didn't you order something at the restaurant?
Bernadette: We did. You never brought it.
Penny: Oh, that's right. Nachos and a turkey club.
Amy: Not even close.
Penny: Well, I was too busy standing up for my friend to worry about your ... I want to say salmon.
Amy: You want to say sorry.

Penny: Do I really force you to do things you don't want to?
Amy: Yeah, but it's okay.
Penny: How is it okay?
Amy: I promised myself if I ever got friends I'd do whatever they said. Really, I'm lucky you found me before a cult did.

Penny: Ooh, we could go horseback riding.
Amy: I actually can't. My hips don't open wider than 22 degrees. I rode a very thin pony once. On the first bump I just popped right off.

Amy: Can you see how a grown man and accomplished scientist who invests in a store that sells picture books about flying men in colorful underwear might be wasting both his financial and intellectual resources?
Sheldon: No.
Amy: Then I think it's a terrific idea.
Sheldon: Great! Wait until you hear about our van.

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.

Amy: You are aware that your ritualistic knocking behavior is symptomatic of obsessive-compulsive disorder?
Sheldon: Is not. Is not. Is not.
Amy: Denial. Denial. Denial.

Amy: Bernadette, I want to thank you for allowing me to be your maid of honor. I also want you to know that I will be happy to do it again if this marriage craps out.

Sheldon: I have some odd freckles on my buttocks. Can I make an appointment for you to look at them?
Emily: Erm, okay, I guess.
Amy: I'm with him three years, nothing. She's with him two minutes and he's taking his pants off.

Amy: If you're keeping him, I've got a cage you can borrow. One of the test monkeys slipped on a banana peel and broke his neck. It was both tragic and hysterical.

Amy: I gave you one job! Keep an eye on him. How hard is that?

Sheldon: Perhaps I should explain. While working with Koothrappali, we discovered an asteroid, and I named it after you.
Amy: Oh, Sheldon, thank you. That's so romantic. But what about Rajesh? He was okay with you choosing the name?
Sheldon: Well, it took a little negotiating, but I wore him down. Uh, we get the asteroid, and if you and I have children, they all have to be named Rajesh.
Amy: All of them?
Sheldon: Even the girls.
Amy: Okay, I think I know what to say now.
