Man, you gotta love the Japanese. The Kasou Taishou, or Kinchan and Katori Shingo's All-Japan Costume Grand Prix, is a special event where groups of performers do special presentations using human-powered special effects and creative performances. One of the most amazing just has to be this skit performed by 9 university students, entitled "Olympic Highlights". Watch, and let your jaw drop in wonder.
