When WWE exploited Punk's expiring contract as a significant aspect of a plot, reality and kayfabe merged. When he gave a scathing, now-famous work-shoot promo on Raw, he became everyone's favorite anti-hero. Onscreen, he vowed to quit the organization if he didn't get the WWE championship. Backstage, he made the decision to resign. CM Punk's career in the squared circle has resulted in a plethora of friends, many of whom are superstars, in both his wrestling and post-wrestling lives. Not just renowned wrestlers, but really mainstream figures. Onscreen, the best of buddies turn out to be the worst of adversaries. While Dana White was thrilled to hire CM Punk as a fighter for the UFC immediately after his WWE leave, he was so disgusted by how horrible his final bout was that he declared that both Punk and his opponent, Mike Johnson, would never compete for the UFC again.
