#4 Jerry "The King" Lawler
Jerry Lawler and Paul Heyman's rivalry, of sorts, began way back in the late 80s when Heyman was known as Paul E. Dangerously and was a manager in various promotions.
The two didn't get along well at all, and Lawler even broke Heyman's jaw when he punched him. Paul Heyman revealed in an interview over a decade ago that Lawler broke his jaw before the scaffold match in 1987.
"Well, he broke my jaw before the scaffold match. He's always taken liberties with other people, especially those who by the nature of the situation had to place some trust in him."
Jim Ross has also spoken about this real-life rivalry between Paul Heyman and Jerry Lawler, where Lawler admitted to breaking Heyman's jaw on purpose:
"And I asked Lawler, he broke Paul Heyman’s jaw. And I asked him point blank, was it an accident or did you do it on purpose? ‘I did it on purpose,’ says Lawler."
Jim Ross also said that their disagreement could be because of cash or creative, but although they disliked each other, there was respect between the two.
