#4 Billy Kidman - WWE Road Agent and Producer
If you were a fan of professional wrestling during the height of the "Monday Night Wars" between WCW and WWE, then it's not arguable that you would all be familiar with the former Cruiserweight Champion (and super high flying), Billy Kidman.
Billy would spend roughly five years in WCW before finally making the jump over to WWE following Vince McMahon's purchase of World Championship Wrestling -- Kidman's contract was picked up by WWE.
Regardless, Billy would continue performing his high flying style in the WWE and on the Indies for much of the early-mid 2000s, before finally hanging up the boots in 2008. Since then (as of 2010), Billy Kidman has been working full-time for the WWE as a producer and road agent.
