This act was around in the 1960's and was featured in this footage from the Ed Sullivan Show, they were the Baronton Sisters from France and could juggle full size tables with their legs and feet.
Hat's off to all of you runners. 5K, half or full. I honestly could not even ride my bike the length of the half marathon, let alone run it. :( But here is one better, a college student named Tom Gounley will run the Boston Marathon and juggle the entire time!
