#4 Brock Lesnar 'kills' Randy Orton
Onto the most recent entry on this list and we go back to WWE Summerslam 2016 when Brock Lesnar faced off against Randy Orton in the main event of the pay-per-view. While anticipation was high, everyone was left bewildered at what transpired next.
"The Beast Incarnate" absolutely mauled "The Viper", busting him wide open the hard way and finally "winning" the bout by TKO. It was so unexpected that even Superstars in the back thought that Lesnar had gone off script and attacked Orton with Jericho even confronting the Conqueror.
Luckily, Vince McMahon cleared things up and said that it was indeed all part of the script.
