ATHENS, Greece - One Olympic athlete better keep his medal around his neck. Greek taxi driver Ioannis Zavos found a surprise in the back seat of his cab - an Olympic silver medal.

The medal had been won by Dutch rower Simon Diederik. He had hailed a yellow cab Monday night and left the medal behind.

Olympic officials notified Athens cab companies after Diederik realized what he had done. There are about 5,000 taxis in Athens, but the medal was found after a two-day search.

The Athens Organizing Committee will be rewarding the cabbie for his honesty.
