Billionaire entrepreneur Elon Musk challenged Vladimir Putin to a bout, calling out the Russian president on Twitter, in Russian.
Musk then tagged the Kremlin Twitter account.
"I hereby challenge Vladimir Putin to single combat," said Musk, translated from Russian. "Stakes are Ukraine."
"Do you agree to this fight?" he said, later saying that it would be "an honour" for Putin to accept his challenge.
Though Elon once told Joe Rogan on his podcast that he practiced karate for a bit as a kid, he would likely be no match for the former KGB agent and taekwondo-trained Putin.
Putin's honorary blackbelt was recently stripped from him, following his invasion of Ukraine.
