It actually made me facepalm (though it did make me laugh as well) when Flair said that. Yes, he's actually beaten a LOT of wrestlers with the figure-four. One of the most notable ones was in an "I Quit" match against Terry Funk at Clash of the Champions. So it was really a bit of self-deprecation on Flair's part despite it not being true.
so he actually has won with the figure4? lol he was before my time i never saw ric flair matches or whatever and always thought that's what made the figure4 great..
he never actually won with it lol! thanks for the history lesson
