This random white guy living in China, “Donnie Does,” was curious if Chinese people think all white people look the same. So, he dressed up like Roger Federer to see if people noticed that he wasn’t Roger Federer. He doesn’t look like Roger Federer.
Weirdly, it appears to have worked, and he was signing autographs on autographs on autographs.
They also did not notice his lack of a Swiss accent, and, more importantly, the fact that he was signing with his left hand.
