Sure, Mark Zuckerberg is the world's youngest billionaire, but he's made some questionable decisions in his 27 years that have drawn a lot of harsh criticism and generated some serious controversy. He's already raised some eyebrows due to the questionable circumstances under which he founded Facebook, and his unfortunate taste in women, but recently, the Zuck revealed what might be the strangest choice he's made since gaining global attention as a wunderkind entrepreneur six years ago. On May 4th of this year, Mark posted a status update (on Facebook. Duh.) that read, simply, "I just killed a pig and a goat."

Naturally, this declaration prompted a lot of questions about how and why a New Jersey-born billionaire was slaughtering farm animals. The answer, it seems, was that Zuck was subjecting himself to another of his "personal challenges." Mark apparently sets goals for themselves at the start of each new year. In the past they've ranged from admirable (learning Chinese) to somewhat strange (wearing a tie every day for a year. Doesn't sound that strange til you picture dude knotting one on to lay around the house on a Sunday). But Zuckerberg's latest self-test has angered animal rights' groups and raised questions about the young CEO's mental health. In 2011, Mark will not eat any meat that didn't die by his own hand. Seriously.

It's part of human nature to want to better yourself and seek out unique challenges. Unfortunately, for someone who basically conquered the world before the age of 30, self-improvement may take strange, extreme forms that may look to us simple-minded non-bilionaire folks like bat-sh!t insanity. Granted, Zuckerberg's latest quest seems a little less insane when you look beneath the surface. Apparently, he hosted a pig roast last year and found that his guests weren't adequately grateful to the guest of honor for giving it's life to provide them with delicious pig meat. As part of an effort to better appreciate his porkchops, Zuck decided that he'd personally slit the throat of every animal he consumed. Weird, yes, but somewhat understandable. What has some people concerned is that this could just be the beginning of Mark's eccentric behavior, and he may be taking his place in a long line of lunatic billionaires.
