#3 The Mandible Claw
The Mandible Claw is known for its viciousness. It enhanced the unhinged nature of Mankind's character. Mankind typically applied this move to a dazed opponent who'd flail his hands and stare wide-eyed in horror.
The mechanics of this move involved putting two fingers in the lower part of the opponent's mouth and using the other hand to pull open the upper part of his mouth. The pain caused by the pressure applied by this maneuver could be so intense that opponents can temporarily lose vision, and at times blacked out.

Because of concerns for hygiene, Mankind wore a sock on the hand he inserted in his opponent's mouth. No other wrestler was known to have adopted this deadly submission move. It was a classic horrifying move that had the crowd on its feet cheering for one of their favorite superstars - Mankind.
