Amy:
Eight years ago, everything I wanted was a crispy sandwich roasted in my mother's George Foremann grill.
Today, everything I want is nothing less than life in all its colors, shapes and ups and downs. And you're not only the reason for that dream, but also the reason for it becoming true. I want to thank you for coming into my life and giving me friendship, appreciation, hope and love. I guess a sandwich couldn't have had the same impact. Whispering and smiling: That's sarcasm, Sheldon, I know it wouldn't have had the same impact.
Sheldon:
As I scientist I need to have theories. Once I had the theory that Sheldon Cooper doesn't need a girlfriend. But then I met you and I realized that I was wrong. So, you became my girlfriend and I had to adjust my theory. Now it said that Sheldon Cooper needs a girlfriend, but not the physical and lovey-dovey stuff that normally comes with it. And as you know, I was wrong again. But I just didn't want to break my theory, I thought it was such a good one. So I tried to hold on it and repair it and adjust it a little when it got cracks here and there... But then there came the day when everything broke down completely and I had to admit the truth: my theory was wrong.
Now I have a new one, and I know that this theory will be proven right every day: Sheldon Cooper loves Amy Farrah Fowler and there's nothing that can hold him back anymore.
