http://www.youtube.com/watch?v=2m0bAWU4gKkYou may have seen this video online in your time following wrestling. Taken from a leaked copy of the raw footage of a Smackdown taping, the match in question was Batista and Rey Mysterio vs MNM (Johnny Nitro/John Morrison and Joey Mercury) in a cage match. Mark Henry was supposed to break the locked door open to interfere and help MNM win.
The story that is normally told is that the cage door was "gimmicked" so Henry could easily break it off, but he couldn't figure out how to do it for minute or two. Thus, time stood still as he tried to get it open, and WWE had to edit the embarrassing gap between when he got to the door and when he actually got it open.
That's not what actually happened.
In reality, the ring crew forget to gimmick the door. After yanking on it over and over in the manner that would've pulled the door off if it hand been properly tinkered with, Henry had to go with Plan B.
It took 40 seconds as it seemed like time stood still in the ring, but Henry legitimately broke the chain that was holding the door closed.
Mark Henry is so strong that when the ring crew forgot to gimmick the cage door for him, he saved the show by breaking a genuine steel chain. If what happened to him happened to any other WWE monster heel (like Kane, who debuted by pulling the door off the Hell in a Cell cage), the angle would've been ruined.
Yet, because some wrestling fans like to irrationally pick on him, he's been branded an idiot who couldn't figure out how to pull off a gimmicked door
The man is just a pioneer.
