S1·E18 What if dust didn't exist?

Nobody likes dust. Attempts to get rid of it are futile; it always comes back. And that's a good thing! Because without dust and its superpowers, life on Earth would hardly be possible. Dust contributes to the formation of rain, it provides nutrients to the sea and the jungle, and it's our personal calling card. Come to think of it, dust might even be able to save the world.
