Amy: Oh, and look at this. A locket. And that stone in front, I bet it's quartz.
Sheldon: This must be it. This must be the actual gift. Open it up. What's inside?
Amy: Nothing. It's empty.
Sheldon: Of course. Our life together is just starting, and they want us to fill it with our memories.
Amy: This might be the best wedding gift ever.
Sheldon: (gasps) They also left us a pair of sunglasses because our future's so bright!
Amy: They thought of everything!
