For those interested in this sort of "puzzle", the story of Benjamin Kyle is fascinating: http://en.wikipedia.org/wiki/Benjaman_Kyle

One thing not mentioned in wikipedia is that he made a White House petition to replace his Social Security Number, which failed with somewhere over 7,500 signatures (but not enough). Kafkaesque.
