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.

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: 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"?

Amy: Sheldon, when I was a little girl, I used to dream about my wedding. But, eventually, I stopped, because I thought that day would never come. And then I met you. From the first moment in that coffee shop, I knew that there was something special between us, even though I did work on a study that disproved love at first sight.
Sheldon: I loved that study the moment I read it. Ironic, huh?
Amy: Clearly, it was wrong. Because I felt something that day, and those feelings have only gotten stronger with time. I can't imagine loving you more than I do right now.
But I felt that way yesterday and the day before yesterday and the day before that.
Sheldon: Is that growth linear or accelerating?
Amy: Accelerating.
Sheldon: Oh, maybe we could graph it out.
Leonard: Save something for the honeymoon.
Sheldon: Smart.
Amy: Sheldon, I don't know what the future holds, but I know that I've never been happier than I am in this moment marrying you.

Sheldon: Are you having an allergic reaction to my boutonniere?
Leonard: No. I'm just so happy for you. And for me. After today, you are officially - and, more important, legally - Amy's problem.
Sheldon: Don't be silly, Leonard. I will always be your problem.

Mark Hamill: Welcome. We are gathered here today in the sight of family, friends and Almighty God.
Sheldon: That's too religious.
Mark Hamill: That lady over there made me say it.
Mary: He heard you, and he can't un-hear you.
