I've seen Alissa Czisny's 2012 Worlds FS a number of times on YouTube, and her injury notwithstanding, I've never seen a skater in any discipline at an Olympics or Worlds have as disastrous a campaign: 2 falls in the short, and 5 falls in the free. The closest that I can think of was Laëtitia Hubert back at Albertville 1992, when she followed a surprisingly solid short with a meltdown in the free, though she didn't fall as much as Alissa did 20 years later. This got me thinking: excluding on-ice disaster/withdrawals such as Mandy Wötzel/Ingo Steuer at Lillehammer 1994 and Yuliya Obertas/Dmytro Palamarchuk at 2000 Worlds, what other disastrous performances at the Olympics and Worlds does anyone recall? By "disastrous", I don't mean a popped jump here or a fall on a twizzle/sit spin there. I mean an epic meltdown in the same vein as Alissa's, irrespective of the skater's talent level or reputation. Because as much as we talk about the greatest performances on the sport's biggest stages, there are many that are the complete reverse. Such performances can be attributed to injuries, lack of training, lack of mental preparation, and just plain ineptitude.
