Halloween revives Zuckerberg's generous streak

Facebook founder and chief executive Mark Zuckerberg is not one to offer a lollipop and send a kid on his way.

A photo posted on his Facebook account appears to show that he offered Halloween guests entire candy bars as treats.

"Kids love whole candy bars," Zuckerberg, a billionaire, wrote below the photo. 

Zuckerberg has been generous with kids in the past. In September, he gave $100 million to Newark's public schools.
