#3 Hulk Hogan
Hulk Hogan and CM Punk have been going at each other's throat for the last few years and they don't seem to be interested in stopping anytime soon. Reportedly, the real-life heat between the two stems from Hogan's actions in WWE's locker room over a decade ago
Speaking on The Steve Austin Show podcast, Hogan once revealed that he got himself into some trouble with WWE's officials as he didn't say "hi" to CM Punk when the two Superstars came face to face after RAW 15th Anniversary.
"I walked into the dressing room for the Raw 15th Anniversary and there was a guy there named CM Punk, I don't know who he is."
While Punk has never mentioned anything about the said incident, he has taken a few shots at Hogan that makes their real-life heat evident. Punk attacked Hogan on Twitter a few years ago after he mispronounced the Chicago Hockey team's captain and coach's name during an interview with ESPN.
Punk was last year asked if he watched Hulk Hogan while growing up, and if he liked him or not. To this, Punk replied by saying he was never a Hogan guy, and doesn't like him, especially after meeting The Hulkster.
