While Jesse Eisenberg was giving his opening monologue on SNL, the real Mark Zuckerbeg make a surprise appearance. Jesse does a great job being awkward giving his monologue, and is first joined by an Andy Samberg version of Mark Zuckerberg. Then the REAL Mark Zuckerberg shows up. Awkward party to the extreme. But since Zuckerberg’s character is to be awkward and nervous, he does a great job. It’s a Jewish party!
