Be it a gold medal or a souvenir from a record relay run, Usain Bolt always gets what he wants at the Olympics. The Jamaican will leave London a perfect 3 for 3 -- three events, three victories -- just the way he departed Beijing four years ago. Almost even with the last U.S. runner when he got the baton for the anchor leg of the 4x100 meters, Bolt steadily pulled away down the stretch, gritting his teeth and leaning at the line to cap his perfect Summer Games by leading Jamaica to the title in a world-record 36.84 seconds Saturday night.
