An Idea Whose Time Has Come
Voodoo Acupuncture. Instead of having to stay still while people poke needles in you, they just take appropriate samples of hair, skin scrapings, and fingernails. Then those things are used to construct an effigy. Needles are then poked into the appropriate places on the doll in order to complete treatment.
The best part is, once the initial figurine is made, there’s no need for the patient to come into the offices! Treatment can be engaged in while the patient is elsewhere, living their life as normal. And they can be billed for a full visit, because the witchdoctor is ministering directly to them through the medium of voodoo.
