Dirt keeps us from falling to the center of the earth due to
gravity.* It would SUCK without dirt (literally): Imagine: 7
billion people all balled up together in the middle?* What a
mess. The vacuum cleaners are fine.* There's a party in The
Abyss right now.* It's run by the Gender Fluidics With Male
Leanings Society, Southeast.* They're an awesome group - they
throw the best parties.* BUT: the HEPA filters WILL SPAGHETTIFY
YOU if you forget to use the Neutrinoficator first.* Just say no
to HEPA. Oh, and with regards to vacuums don't even MENTION
Dyson.* His Sphere has negative gravity and we all get stuck to
the far inside of it like a bad carnival ride that spins and
spins and never ends.* When that kid next to you throws up his
lunch, it splats on your face.* Awful stuff.* He needs to work
on his design more before that Star Trek movie comes out in a
dozen or so years in the past.
