Low-key might be Bret/Taker at Summerslam. Kicked off the Taker/HBK feud which birthed HIAC & Kane. HBK winning led to him facing Bret at SS which led to the screwjob. The screwjob led to the ‘Bret screwed Bret’ promo on Raw which birthed the Mr McMahon character. HBK dropped the belt to Austin at WM which led to the Austin/Mcmahon feud and the rest is history.
