Ed Stafford once responded to the problem of "the sheep's head is stuck" in his documentary "Life on a Desert Island". He said it was the late stage of the 60-day challenge, but in fact he had no hope of shooting goats. When he passed the big tree, he hardly noticed the goat, but he didn't realize it until he heard the goat's cry when he passed by. He was allowed to eat goat meat for eight days, but this was not arranged by the film crew. The goat really stuck its head out by itself.
