YouTube comedian convinces Shanghai shoppers that he's Roger Federer

Shanghai YouTube comedian and resident impugner of the good name of the people of Massachusets Donnie, recently took to the streets of the city dressed as Swiss tennis superstar Roger Federer to see if, to Shanghai shoppers at least, 'all white people look alike'. Apparently they do. 

"Roger" was mobbed. "Roger" kissed babies." "Roger" signed autographs. "Roger" made an appearance at a Nike store. Watch the scam unfold below.

There are going to be some very disappointed Shanghai tennis fans when this video hits the Chinese web.
