#3 Stone Cold Steve Austin sells his soul: Wrestlemania 17
During the Attitude Era, there's no doubt that one major rivalry not only made for compelling television, it also helped the WWE turn the ratings war around on rival WCW and eventually led to their total victory; Vince McMahon vs. Stone Cold Steve Austin.
At this point, McMahon was openly the owner of WWE, acting both as CEO behind the scenes and as the villainous Mr. McMahon character on screen. Stone Cold's drinking, cursing, and refusal to tow the company line made for bitter friction between the two men.
McMahon struggled first to prevent Austin from winning the title and then fought hard to get it off of him. But at Wrestlemania 17 the two men swerved the world, teaming up on the Rock to ensure Austin's victory and title reign.
The sight of McMahon and Stone Cold shaking hands is one of the most chilling things the WWE Universe has ever beheld, and it made for a classic heel turn.
