Mo Farah was all smiles just two weeks ago, as he spoke during the Sainsbury's Birmingham Grand Prix on June 6. But everything changed after a documentary by BBC's Panorama and ProPublica was broadcast. The program raised questions over the methods of Farah's coach Alberto Salazar.

Farah's "Mobot" celebration became his trademark winning routine.

Even the fastest man in the world, Usain Bolt, got in on the 'Mobot' act.
