Mastodon Dentist-27: Oddly Shaped (Volume 27)

The 27th installment of Mastodon Dentist...What do you see when you look at me? Well personally you can't, I am less than a ghost. I'm what you picture in your mind's eye, maybe I'm surrounded by a place you know, maybe you imagine me as white, black, heavy, slender, tall or short. Maybe I'm some or all of these things. Who knows?
