Usain Bolt isn't the only showman in the track world.

Seconds after Mo Farah won the 5,000 meters Saturday night and completed an Olympic distance double gold for Britain, he dropped to the track and did a few playful sit-ups.

That came in response to the antics of Bolt, who did a few push-ups immediately after winning the 200 meters earlier this week.

Bolt should get another turn to one-up the popular British distance runner later Saturday after he anchors Jamaica's 4x100-meter relay team.
