A tipster sends this shot of Facebook founder and CEO Mark Zuckerberg with Mashable's Pete Cashmore. Our tipster says the photo captures Zuck and Cashmore "drunker than skunks." Don't buy it. Zuck's got a straight-edged reputation and he's holding a bottle of Crystal Geyser, not Cristal. A better explanation for Zuckerberg's awkward pose? He's camera-shy. That jibes with what Zuckerberg told egoblogger Robert Scoble during a three-hour walk the pair took around Davos over the weekend.
