Church of Body Modification

http://uscobm.com/ 
The Church of Body Modification is a legally recognized religious body in the United States.  They believe that modification of the body is essential to spirituality and to becoming truly healthy and complete because the mind, body, and soul are all inextricably interconnected.  They declare that they respect those who choose not to modify their bodies.

Body modification techniques include scarring, piercing, insertion of objects (such as needles and metal balls) under the skin and into body parts, splitting of the tongue and/or sexual organs, insertion of posts into the skull onto which objects can be attached, removal of teeth and replacement with prosthetic fangs, multiple versions of appearance changing contact lenses, hanging the body by removable hooks, etc.  Extreme body modifications include the surgical removal of healthy organs (tongues, external ears, eyes, etc) and appendages (such as fingers, fingernails, feet, arms, and legs).
