Phelps notches fifth gold medalMichael Phelps had every reason to be satisfied after the Beijing Olympics. Yet he kept insisting there was more to do in the pool. Clearly. Even coming off his longest layoff and the embarrassment of being photographed inhaling from a marijuana pipe, Phelps turned in another remarkable performance over eight days at the Foro Italico. He completed it Sunday night by helping the U.S. 400-meter medley relay team set the 43rd world record of the fastest meet in history.
