Jessie Eisenberg, the actor who plays Zuckerberg in "The Social Network" and is up for an Oscar as Best Actor, hosted the show Saturday night and was joined onstage during his monologue by SNL regular , who was playing Zuckerberg and uttered "All hail the Zuck!"", and then by Zuckerberg himself.

Supposedly, Eisenberg and Zuckerberg had never met until then.

MONEY MATTERS:  

BEST AND WORST:  

Before Zuckerberg came on the stage he was shown backstage with SNL Executive Producer Lorne Michaels. Watching the monologue together, Zuckerberg commented:  "Those guys are such nerds. C'mon, I invented Poking." To which Michaels replies that Zuckerberg is better off backstage.
