I got to say, that title is open to interpetation. I expected to see a far different idea of what the worst moment was/is. For me:
Wrestling's worst real-life moment (which I originally thought this was) would have to be the death of Owen Hart. Never before or since have I been affected emotionally as much as his accident in the ring and having to hear his death announced live on PPV. A close second would be the passing of Eddie Guerrero, just for the fact that he was one of my favorite wrestlers and that I had really believed he had finally turned his life around.
Wrestling's worst scripted moment (which is where I think your robocop entry would fall in) would definitely be David Arquette winning the WCW title. Second would be anytime Steve 'Mongo' McMichael was anywhere near a wrestling ring.
I always thought that David Arquette tried hard to make the gimmick work. His promo after beating DDP had dick-heel written all over it. I've always believed that, given a chance, he could have been successful. I think the fans and the IWC were far too hard on him.
Worst moment ever was when Vince McMahon bought WCW.
People who jump from one reality show to the next need to be shipped off the planet. Anyway, I may be in the minority, but I miss the first season or two of Tough Enough when you had fairly wimpy guys in their early 20's trying to make it.
