Morgellons Disease is an intelligently designed radio-receptive nanotech invasion of living human tissue
Morgellons is a very odd phenomenon on its own. It even has its own Morgellons Research Foundation now. The mashup meme of a strange new skin disease (dermatology problems are the most disgusting things I can think of) plus alien implant/conspiracy is crazy fascinating. I guess this would be promising vector for invading aliens, remaking a planet's inhabitants into yourself through nanotech.
