#1 Jeff Hardy exorcises the demon known as CM Punk (Night of Champions 2009)
CM Punk won the Money in the Bank ladder match two years in a row. He used it to defeat Edge in 2008, and the fans loved him for it. It was a short-lived reign before WWE was ready to embrace Punk as a true World Champion. Cut to a year later -- Punk is Mr. Money in the Bank again, and this time he's not a good guy. Jeff Hardy won a ladder match at Extreme Rules to win the World Heavyweight Championship from long-time rival Edge. CM Punk, however, not a fan of storybook endings, cut Hardy's party short by cashing in his MITB contract and taking the title from a bruised and battered Hardy just moments after a brutal ladder match.
Hardy would get his rematch the following month at The Bash, but CM Punk got himself disqualified, so it went one more round. Hardy took on CM Punk at Night of Champions, and this time, without the advantage of surprise (and a grueling match having already taken place), and being aware of Punk's ability to cheat to win, Jeff Hardy was ready. CM Punk was not up to the challenge, and he would lose the belt back to Hardy. This match is so important because it was the beginning of Hardy's swansong with WWE. The match was great and it was a feel-good moment for Hardy and all of the fans, but it was significant because it would be the last time he would win gold in WWE for a very long time.
Shortly after, at SummerSlam, CM Punk would win the belt back again from Hardy in a TLC match. Then, in a rematch on SmackDown inside of a steel cage, Jeff put his career on the line for one last shot. He was unsuccessful and left the company. He would resurface about 4 months later in TNA but didn't appear in a WWE ring again for almost 7 years, when he and his brother Matt returned at WrestleMania 33 in 2017.
