- 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.
- Amy Farrah Fowler: [chuckles] Sheldon...
- Sheldon Cooper: 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 Farrah Fowler: Okay, I think you're getting caught up on the ways I'm not like dark matter.
- Amy Farrah Fowler: Okay, let's see what we've got so far. I arrive in a Little House on the Prairie style horse-drawn buggy.
- Sheldon Cooper: Where you are met with an honor guard of stormtroopers.
- Amy Farrah Fowler: Do you think that might be jarring, going from wholesome pioneers to space Nazis?
- Sheldon Cooper: I see what you're saying. You're thinking that you should arrive in a replica of Luke Skywalker's landspeeder.
- Amy Farrah Fowler: It's not what I'm thinking, and to save you the trouble for the future, it will never be what I'm thinking.
- Sheldon Cooper: What do you think will make the wedding worse for Amy: a cake made with salt instead of sugar or a cake iced with congealed gravy?
- Leonard Hofstadter: That is a trick question. The answer is: you as the groom.
- Sheldon Cooper: Neither of them will be the actual cake. I'm just using it as a bargaining chip to get Amy to agree to the whole wedding party getting rings and us getting one ring to rule them all.
- Dr. V.M. Koothrappali: I'm just saying, if you replace Howard with a 22-year-old grad student, your confidence will soar.
- Amy Farrah Fowler: Instead of throwing confetti, we'll release butterflies.
- Sheldon Cooper: Airborne worms! Have you lost your mind?
- Sheldon Cooper: You know, we did get dressed up and come all the way to city hall.
- Amy Farrah Fowler: What are you thinking?
- Sheldon Cooper: I have always wanted a permit to dispose of hazardous waste.
- Amy Farrah Fowler: Let's do it.
