#4 AJ Styles punches Vince McMahon backstage at WWE SmackDown
On the Christmas Day edition of WWE SmackDown in 2018, Vince McMahon and AJ Styles had a discussion backstage. It resulted in The Chairman firing AJ Styles up and also slapping him to get a reaction. Vince claimed that AJ had an animal inside of him waiting to come out.
In the end, AJ Styles retaliated by punching Vince in the face and knocking him down. The sad thing about this segment is that it never really led to anything significant, but it made a great visual for the WWE Universe.

#3 Brock Lesnar gave Vince McMahon an F5 on WWE RAW
Nobody is safe when Brock Lesnar is around, not even Vince McMahon. Lesnar interrupted Paul Heyman's job evaluation in 2013, and after the pair had a face-off in the middle of the ring, Vince warned Brock not to do something he would regret.
Brock decided to hoist The Chairman up and deliver an F5, which broke Vince's pelvis in the storyline, requiring surgery.
