In a Q&A hosted on Facebook Live, the social network's new live streaming feature, Facebook CEO Mark Zuckerberg answered some of his followers' most pressing questions -- including whether he's actually human.
"Mark, are the allegations true?" one Facebook user asked. "People are saying you're secretly a lizard. Please confirm."
"I'm going to have to go with no. I am not a lizard," Zuckerberg replied.
The Q&A received 8.2 million views worldwide. At one point during the unedited session on Facebook Live -- a new feature the company is promoting heavily -- Zuckerberg got the hiccups.
He discussed a range of topics: how his daughter Max wakes him up earlier than he'd like ("Max is a pterodactyl. I didn't know a human could make those noises"); his efforts to build an A.I. system for his home; whether Facebook would ever charge its users ("We're not going to charge. That's why we're ad-supported"); and how he recently broke his arm, falling off his bike while training for a triathlon.
Towards the end of the hour-long session, Zuckerberg brought in a surprise guest, comedian Jerry Seinfeld, who was visiting Facebook headquarters to check out its new Oculus virtual reality goggles and promote the new season of his web series, "Comedians in Cars Getting Coffee." Seinfeld said he wanted to know what Zuckerberg does first thing in the morning.
"The first thing I do is look at my phone," Zuckerberg said, laughing. Since he doesn't yet have his contact lenses in, Zuckerberg said he has to hold his phone right up to his face to read the screen. "I didn't expect to talk about this publicly," he added.
Another burning question Facebook users asked Zuckerberg: "Does your girl call you dadada?"
Hackers, who recently breached Zuckerberg's Twitter and Pinterest account, claimed they obtained Zuckerberg's surprisingly weak password, "dadada," from a database of stolen passwords taken from the LinkedIn hack in 2012.
