Chinese Panda takes big bite off boy's leg

15-year-old Li Xitao found his lesson pretty painful when male panda Gu Gu took a huge chunk of flesh from the boy's leg at the Beijing Zoo. The bite was so deep that the boy's bones were even showing! Seems curiosity took the better(or worse) of the boy when he jumped over the 4-ft 7-inch barricade around the panda grounds. Gu gu was in the news before for being bitten by a drunk man, which was in retaliation for Gu gu biting him first.
