I had, like one and a half times. Sure, everyone has a Swiss Army Knife, duct tape, rope, and an empty tin can in their pocket when they fall out of burning airplane in the middle of the Yukon, and sparking a fire with two sticks is invisible which is why it never happened on film during the show, and he's all alone which is how a camera is filming him from 100 yards away as he trudges through two feet of snow. But one important survival skill I got from the show is never ever go anywhere that doesn't have 24hr bus service.
