Sheldon Cooper: 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. Plus, plus, you interact with light, so I can see you. And, also, you don't account for the missing mass in the universe. But when you make a discovery like this, you don't just take it down to City Hall... you tell the whole world. And so I'll say it in Latin or Klingon or-or smoke signals, if-if that's not cultural appropriation.

Amy Farrah Fowler: It is.

Sheldon Cooper: Okay, so not smoke signals. But I want to do this right.
