As I wandered, I came upon what looked like a floating worm. It hovered about three feet off the ground; at its base was a pile of coiled loops that led up to a twitching bulb the size of a football, then a single segmented tube that extended upright until it ended in an opening. It turned toward me. At the top was a human mouth—the “worm” was a disembodied esophagus and digestive tract, ending in the bundle of small intestine. At the bottom it possessed an anus and, in the front, a six-inch-long erect penis.
