SNL‘s Andy Samberg channeled his inner geek to spoof Mark Zuckerberg Saturday night. Samberg delivered jokes about youth culture and Facebook, the central theme of the hit movie The Social Network.

Samberg’s wasn’t the only impersonation of the night (it would hardly be SNL without several to choose from). A new cast member offered up an impression that was so spot-on, the audience didn’t know whether to laugh or just stare in awe. Follow the jump to view the video.

In this sketch featuring host Jane Lynch, Jay Pharoah performed a Denzel Washington impression that was perfect enough to fool casting agents.
