Penny: What are you lunatics doing?!
Amy: Sheldon had a breakthrough.
Sheldon: Actually, Amy and I had a breakthrough.
Penny: Oh, science? Shocking!
Leonard: You don't understand. This could be really big.
Sheldon: No, Penny's right. We have our whole lives to do science together.
Amy: Let's get married.
Penny: All right. It's go time! I am pumped!

Penny: At one point, they had me figure out how to get a banana out of a puzzle box.
Leonard: Wait, Sheldon gave me a banana in a box. He was testing me, too.
Penny: Unbelievable.
Leonard: And how could a chimp even solve that? That was impossible.
Penny: Really? You couldn't get it out?

Leonard: If I take it off, Sheldon wins.
Penny: Sweetie, every night you don't kill him in his sleep, he wins.

Sheldon: Woman, you are playing with forces beyond your ken.
Penny: Yeah, well your Ken can kiss my Barbie.

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: 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.
