Every once in a while, it's good to be reminded just how much information we're giving to complete strangers every day, and I'm not talking about the NSA. In the clip below, comedian Jack Vale finds people who are posting public social-media updates near his location, then approaches and shocks them with the level of detail he knows about their lives. Birthdays, pet names, parents, recent meals … he seems to know it all, only revealing at the end of the conversation that he got the info from their Twitter and Instagram posts. "I wanted to see how easy it would be to get personal information from complete strangers," he explains in the intro, "and while I'm at it, of course, freak them out a little bit." Mission accomplished. Now go update your privacy settings. Via The Presurfer.
