Usain Bolt had reason to celebrate Sunday night. He had just defended his gold medal in the 100 meter dash, quieting the copious doubters and asserting his place as one of the greatest sprinters in history.

But Bolt did not let his success get to his head. In a nod to the spirit of the Olympics, Bolt stopped an interview as the United States' national anthem played at Olympic Stadium after Sanya Richards-Ross won gold in the 400 meters. He even turned away from the camera and the interviewer in order to face the flags.

An extremely classy move by the world's fastest man.
