Mark Zuckerberg Takes Questions From Stephen Hawking, Arnold Schwarzenegger in Bizarre Q&A

Facebook held one of its regular Q&A Townhall sessions with Mark Zuckerberg Tuesday. Rather than a live event with Zuckerberg answering questions from a live audience, the question and answer session was in AMA format on the CEO's timeline.
But Tuesday's Townhall took a turn for the weird when a handful of Facebook's more high profile users, including Stephen Hawking, Arnold Schwarzenegger and Arianna Huffington, chimed in with their own questions for the Facebook boss.
