I found this fascinating quote today:
Yesterday I received an e-mail from a colleague with images of a five headed cobra supposedly found in “Kukke Subramanya, Near Mangalore, Karnataka, India”. The colleague in question seemed to believe that this is a real snake. Being of Indian descent she has been exposed to the idea of the five headed snake god Nagaraja, and she happily accepted that the snake in the e-mail is an earthly representation of the myth.
