Zuckerberg meet Zuckerberg? Saturday Night Live is trying to lure the real Facebook founder, Mark Zuckerberg, to make a cameo on the show this weekend, when Jesse Eisenberg will host. Zuckerberg, who was portrayed by Eisenberg in the Oscar-nominated film The Social Network is reportedly interested in a walk-on. The young billionaire would like to show the public that he "has a sense of humor," Page Six says. No word from Zuckerberg or SNL's reps, but one source says, "They add and throw things out right up to the broadcast, so nothing is guaranteed."
