Michael Phelps gets another gold, but says it is the last (Yahoo Sports)

Standing atop the medal podium for the 23rd time, Michael Phelps teared up, bit his lip and gave a little nod. ”It turned out pretty cool,” Phelps said, another gold medal around his neck. Phelps put the United States ahead to stay on the butterfly leg of the 4×100-meter medley relay, giving the most decorated athlete in Olympic history his 23rd career gold medal Saturday night.
