Kind of off topic, but I just thought about something. They said they gave Naurto the surname Uzimaki so that people would not know that he is the son of the 4th, but it looks like his mom was one of the only Uzimaki's seen in the village. Add to that, I am sure that people knew who the Hokage's wife was and that a baby popped up with the kyuubi in it the day she mysteriously dies. It does not seem hard to put 2 and 2 together here.
