Russian media published on Friday calls by two comedians to the World Anti-Doping Agency (WADA) and the US Anti-Doping Agency (USADA) pretending to be Ukrainian Sports Minister Ihor Zhdanov.

Pranskters Vladimir Kuznetsov and Alexei Stolyarov separately called WADA President Craig Reedie and USADA chief executive Travis Tygart, according to recordings published online by Sputnik, a Russian state-owned news agency.

Sputnik said the two callers "managed to trick" the two anti-doping officials "into revealing the truth behind the doping scandal." They made the calls for a comedy show on Russia's NTV channel, which was shown on Friday evening.

Kuznetsov asked Reedie whether he thought the results of the 2014 Sochi Winter Olympics should be revised in light of the doping scandal. Reedie said that he didn't yet see proof of Russia's wrong-doing and advised the caller, believing him to be Zhdanov, to await the results of the investigation.

Stolyarov also asked Tygart whether Sochi biathlon results should be revised, resulting in Ukrainians gaining medals awarded to Russians. Tygart said that this could potentially happen, but also said this would depend on the investigation.

Kuznetsov and Stolyarov have a history of making embarrassing calls to celebrities.
