Jesse Eisenberg, the actor who portrayed Mark Zuckerberg in The Social Network, was the host of Saturday Night Live last night and so rumor was running rampant that the real Mark Zuckerberg would show up on set.

Here is the monologue clip:

In my opinion the most comfortable looking Mark Zuckerberg on stage was Adam Samberg.

I also just realized that all three of their names end in berg. Weird huh?
