Human bones as a "miracle cure" for gout; living mummies buried alive; a truly bizarre Victorian way to lose weight -- with tapeworms; from daily rites to once-in-a-lifetime rituals, the stranger side of human nature is revealed in these rituals.

Sometimes the strangest things on Earth...are happening just below its surface. From tunnels carved by giant sloths to desperate attempts to stop the dead from rising again--these are the weird and wonderous tales of the sea beasts, hidden cities and impossible creatures that lurk beneath us.
