Sheldon: I want a real wedding.
Amy: Well, Sheldon, it was just making us fight.
Sheldon: I know. But, Amy, I never thought I'd want to marry anyone. So the fact that I found you is astonishing. It's-it's like finding dark matter, except they're looking for dark matter. I wasn't even looking for you. S-So you're even better than dark matter.
Amy: (chuckles) Sheldon.
Sheldon: Plus, plus, you interact with light, so I can see you. And, also, you don't account for the missing mass in the universe. Oh, and-
Amy: Okay, I think you're getting caught up on the ways I'm not like dark matter.
Sheldon: Right. Sorry.
