Talented GREY'S ANATOMY star Patrick Dempsey was a teenage juggling sensation. The hunky actor came runner-up to juggling guru ANTHONY GATTO at the International Jugglers Competition in Cleveland, Ohio when he was 15. Dempsey says, "Anthony is probably the best juggler in the world right now." And juggling isn't the actor's only circus-related talent - he taught himself to ride a unicycle in a year. He adds, "I just didn't give up."
