Facebook founder Mark Zuckerberg met his alter ego for the first time Saturday night, appearing in the opening monologue for “Saturday Night Live” with host Jesse Eisenberg, who played Zuckerberg in the Oscar-nominated “The Social Network.”

The result was an example of both why Zuckerberg is a dot-com billionaire and not an actor, and why I don’t bother watching “SNL” anymore.
