In asia and particulary in thailand...guys like girls can born with a tail there..this is a genetic disease...and the more important things is that the tail can be remove with a surgery without consequences or probem for the patient..but i think thisis more a problem of money than other things that make this guy keep his tail....
hahaha.....damnnn.......dat is weird......reminds me of a film called "shallow hal" n the main characters friend has a tail, well extended spine thing lol.
