A friend of mine sent this http://www.youtube.com/watch_popup?v=BNR74UCidBI&feature=player_embedded in an email. It's a video of three women contortionists. In the beginning they're just singing about potato salad, which I now find myself singing throughout the day, strangely enough. As the video progresses they perform amazing acts of contortionism. Very strong little women.
While I thought these women were pretty amazing, I doubt they can do this.
