#7 Chris Jericho and Brock Lesnar
SummerSlam 2016 will probably be remembered for two things: John Cena and AJ Styles having a fantastic match, and Brock Lesnar destroying Randy Orton’s forehead.
At that event, WWE decided to try and make things look more ‘real’ by having Lesnar win his match via TKO after he busted Orton’s head open the hard way, meaning with real strikes and without the use of a blade. Because of how well it was executed, most people watching backstage thought it was a shoot, and that Brock Lesnar really decided to turn Orton’s head into a practice dummy.
Chris Jericho wasn’t happy about this and demanded to know the truth behind this match. But Michael Hayes, one of the top members of WWE’s creative department, was ordered to keep the finish a secret, to which Jericho responded, ‘bulls**t’. Lesnar came through the ring curtain at that moment, and thought the comment was aimed at him instead of at Hayes and creative.
The two of them got into a very heated verbal argument that involved cursing, taunting, and even shoving. Depending on whom you ask, it’s further alleged that Vince himself had to interfere to de-escalate the situation. Nobody was punished in the end, and SummerSlam 2016 ended with yet another interesting story about it.
