We all agree that "that 70's show" is one of the best sitcoms ever... Have you noticed that they never tell us where Fez comes from?!
This is true; but the secret is his name; FES= Foreign Exchange Student
All we know is that Fez is forigen. I don't think they ever tell you where he is actually from.
In one episode he says he flew to brazil to go back home...but then when they ask him if he's from brazil he says he is only going there to take a plane to his country!! I found it really funny!! you can even find it in wikipedia!!:)
