By "double switch" I mean a match where wrestler a turned from face to heel and wrestler b turned from heel to face, or vica-versa, with both men switching places.
I dont seem to remember this happening many times, only a handfull.
Bret Hart turned heel while Austin turned face by the end of their WM 13 match.
Flair and Hogan did a double turn at WCW Uncensored 1999 (I could be wrong about this one), wasn't it during the First Blood match that ended in a pinfall ? classic WCW stuff
Mankind vs. Rock, Survivor Series 98'. Mankind was being groomed by Vince to be a champion while the Rock was the babyface trying to get a shot at it, and by the end of the night it was the other way around and Rock became Corporate Rock.
Any others out there? Any favorites?
