Actor Jesse Eisenberg hosted NBC’s Saturday Night Live last night, and his monologue became a “Berg” paradox that should have destroyed the entire universe. Instead, we got an awkward and hilarious moment between Eisenberg, who plays Facebook co-founder Mark Zuckerberg in The Social Network, Adam Samberg, who plays Zuckerberg on SNL, and Zuckerberg himself. Also, this is apparently the first time Eisenberg and Zuckerberg have met. Watch it yourself after the break.
