Survivor Series, November 1997: Montreal Screwjob
The Montreal Screwjob, or 'Le Screwjob de Montreal' as they call it in Quebec (We think? We don't speak French, so we tend to let the funky music do the talking) was one of the most notorious incidents in wrestling history.
It was also one of those awkward moments were real-life tensions bled into scripted storylines. In short, outgoing WWF Champion Bret Hart was asked to lose the title to Shawn Michaels at the 1997 Survivor Series before leaving the company, but he had a creative control clause in his contract that allowed him right to refusal.
Hart didn't want to lose the Championship to real-life rival Michaels in his home country, and so proposed dropping the title the following night on Raw. WWF management, concerned Hart was about to waltz onto WCW programming with the WWF title in his possession, decided to take matters into their own hands to ensure he didn't leave Canada with the WWF title in his suitcase.
At around the twenty-minute mark of the match, Michaels snared Hart in "the Hitman's" own patented Sharpshooter submission hold.
According to the script, Hart was supposed to reverse the hold and make good his escape, but instead the ref called for the bell, leaving Hart bemused and angry in the ring.
The infamous moment would later be recreated in 1001 copycat wrestling storylines. It's been strongly hinted in the recent DX trailer (very strongly, in fact) in that WWE '13 will allow you to make that 1002.
