One of nature's most fearsome creatures found itself in a distressing situation. An Indian cobra got its head stuck in a beer can. Two rescuers used a knife to cut away part of the can, allowing the venomous reptile to extract itself. As soon as it was free, the cobra lunged, bearing its distinctive hood. But the rescuers were unperturbed and used a metal prod to pick it up and move it to more hospitable surroundings.
