After garnering a Best Actor Academy Award nomination for his role as Mark Zuckerberg in the 2010 hit The Social Network, Jessie Eisenberg was invited to host Saturday Night Live. But Lorne Michaels decided to turn things up a notch and invited the real Mark Zuckerberg, who had lambasted the movie for being wildly off-base, to swing by 30 Rock and meet his famous impersonator. The result was awkward as hell, but we give props to Zuck for being able to laugh at himself.
