#3 Titus O'Neil

Titus O'Neil is one of the prime examples of why a WWE Superstar should never ever enrage the WWE Chairman, Vince McMahon.
After Daniel Bryan's retirement ceremony, Vince McMahon was heading to the back through a crowd of WWE Superstars. Titus decided to get handsy and apparently grasped the arm of the WWE Chairman. Vince McMahon is known for being one of those people who doesn't mind contact, but Titus' timing was clearly very off.

He shoved away Titus O'Neil and was furious with him. On returning backstage, Titus O'Neil was suspended for 2 months. Usually, a WWE Superstar is suspended for so long after violating the WWE Wellness Policy twice, but it also appears that is the same as grabbing the arm of the Chairman.
Mr. McMahon felt that the ramp was still visible to the public and by doing this Titus was breaking kayfabe.
Titus O'Neil really needs to work on his timing.
