If you stop to think about it, it really is remarkable just how many of Hulk Hogan's trademark characteristics and "unique" personality traits were originally introduced to the wrestling world by "Superstar" Billy Graham, even though he rarely receives credit for his ideas.  And that's not a knock on The Hulkster, but rather, simply an undeniable fact.  I truly believe that had "Superstar" Graham not existed, and Terry Bollea had not been able to draw from that source, then neither would the Hulk Hogan character have existed -- at least not as we know it.  There are just too many distinct similarities for one (Hogan) not to have been influenced by the other (Graham).
