Here's an important life lesson: don't taunt bears. Authorities at Cades Cove National Park in Tennessee is reminding visitors to steer clear of wildlife after a man was filmed being charged by a mother bear after approaching her cubs. An on-looker says she was filming the family of bears when a man approached the cubs and started making sounds at them. The mother bear lunged at the man, but he walked away without injury-- no word on if his ego suffered after other park visitors swore at him and called him an idiot. Park officials released a statement telling visitors to give space to wildlife.
