Today marks the 20 year anniversary of what many consider to be the most important match in professional wrestling history, when The Undertaker threw Mankind off the top of the Hell in a Cell.

The match was featured as one of the main events of the 1998 King of the Ring PPV and it set the standard for all matches that would follow. Both wrestlers found themselves exchanging blows on top of the 16-foot-high cell with the chain-link buckling beneath them.

Then history was made. The Undertaker threw Mankind from the edge of the cell and sent him plummeting into an announcer's table below. That's the moment that gave us the Jim Ross exclamation, "Good God almighty! Good God almighty! That killed him! As God as my witness, he is broken in half!"

The match didn't end there, as Mick Foley (Mankind) was being wheeled away on a stretcher he got up and walked back to the ring. He climbed back up to the top, where the Undertaker met him, and resumed the match.

Eventually the Undertaker choke-slammed Mankind through the top of the cell causing him to fall to the mat below. After a few minutes the match continued and he was choke-slammed into a pile of thumbtacks. Undertaker ended up winning after performing a Tombstone Piledriver on Mankind.

Foley ended up suffering a dislocated shoulder and jaw, was knocked unconscious for a few moments, and he lost a tooth. Undertaker broke his foot during the match.
