Ricky McGee picked up a hitchhiker in Australia on January 23rd of 2006, who ended up drugging him. He woke up under a tarp and rocks only to find that dingos were trying to eat him.
After scaring them away he found himself alone in the Australian Outback, and managed to survive for 71 days eating leeches, snakes and frogs. He lost over 125 pounds, but was rescued by a rancher who came upon his makeshift campsite.
