If a guy picks you up, be careful. He's a big fan of dead breasts.

Thing is, do you even know that that's not the anatomically accurate ghost costume? Perhaps when we die, only most of our body turns into an ethereal vapor, every part of us except our most attractive feature (for some: the boobs; for others: the small of the back; for still others: the left testicle, the one with character). Just your most appealing physical feature retains its earthly flesh to tell everyone in Heaven, "This is what got me a leg up back when I was alive." So walk around as a boob ghost on Halloween and if anyone tells you boob ghosts aren't real, you tell them heaven is whatever we want it to be. And if you want it to have boob ghosts, dammit, it's gonna have boob ghosts.
