5 greatest unscripted moments in WWE history

#1. Vince McMahon tears his quads

A fumbled finish is one of the best ways that WWE can evaluate its stars. How one reacts to the moment is key, and the spotlight was on Batista and John Cena at the 2005 Royal Rumble.

The Animal was supposed to win the battle royal by eliminating the leader of Cenation, but both superstars fell out of the ring at the same time, landing almost perfectly in sync.

WWE officials stood and argued inside the ring for a few minutes before a furious Vince McMahon stormed down from the back. While the unscripted ending saw chaos in the ring, the addition of the Chairman added fuel to the madness.

As soon as he entered the ring, Vince blew both of his quads and toppled over. Unable to stand, he sat against the ropes and screamed at Batista and Cena while the audience gaped. And despite being in immense pain, the WWE Chairman managed to get the Rumble restarted with just the final two participants.

This time, the finish went according to plan, and Vince headed backstage without alerting the fans. Both the botched ending and McMahon's injury are hands-down two of the craziest unscripted moments in WWE history, and amazingly, both happened within a span of minutes.
