Never before has the human body been twisted into such extraordinary positions in service to the American Potato Salad Industry. May I present the mysterious Ross Sisters - Aggie, Maggie and Elmira - in footage from the 1944 MGM musical Broadway Rhythm. As it was described on Metafilter, it's Hee-Haw meets Cirque du Soleil! Stay tuned for their amazing triple cartwheel finale - download mpeg video (12 megs) or youtube it. Thanks Bell!
