Will the real Mark Zuckerberg please stand up? The Facebook founder dropped in on the Saturday Night Live stage alongside host Jesse Eisenberg, who portrayed Zuckerberg in the Oscar-nominated film, The Social Network. There were rumors that SNL was luring Zuckerberg to make an appearance on Saturday's show. Eisenberg was first amused by Andy Samberg, who often plays the hoodie-wearing Zuckerberg on the show. But Samberg quickly left the stage as the real Zuckster emerged from backstage. The young billionaire has publicly stated the film was inaccurate, but told Eisenberg he thought it was "interesting." "I'll take that," said Eisenberg, and the two shared a high-five.
