#1 Donald Trump (WrestleMania 23 - April 1, 2007)
Now a WWE Hall of Famer, Donald Trump was once the focus of the ire of Vince McMahon in a 2007 storyline that saw him purchase WWE. This led to WrestleMania 23's "Battle of the Billionaires" which saw Trump's chosen wrestler, Bobby Lashley, take on McMahon's charge, Umaga. If the former were to take home a victory, Vince McMahon would get his head shaved bald. If it were the latter, then the infamous hair of "The Donald" would be shorn.
With Stone Cold Steve Austin as the special guest referee for the contest, Lashley and Umaga fought it out for their respective leaders, surely with a big monetary incentive for the winner. Lashley would come out victorious and while Vince McMahon was still the owner of his billion-dollar franchise, he was no longer the owner of a full head of luxurious hair.
In the end, there are so many Stone Cold Stunners that will stand the test of time, but this one may indeed be the absolute best. It was already great because of the fact that it was a spectacular moment, but it was also possibly the worst Stunner of all time from a visual standpoint. The only other one that comes close is the one taken by Linda McMahon (see entry #5) -- they're almost neck-in-neck, but Trump's flopping folly of a fall probably takes the cake.
