It appears that the best way to get as much as possible American conspiracy political myths out in a thread is to start a thread saying that's exactly not what you need. Jeez, guys..
Anyway.
There was a local conspiracy theory saying that former Yugoslavia's life long boss-man, Josip Broz Tito, was eliminated (I think) while visiting the Soviet Union, and replaced with a Soviet agent who looked identical to him. As "proof" the conspiracy theorists claim that Tito lost one of his fingers as a child but the man who claimed to be the illustrious Marshall had all of his fingers. There was a variation of this theory that only varied in the place where Tito was supposedly murdered and replaced.
At some point there was a bit of talk about that in Croatia, but I haven't heard anything on it in years and I doubt many people believed in it in the first place.
You can find a bit more about it
