You've heard the one about the animal walking into a bar... But for one pub owner, it became a reality.

The owner of Irish bar Lonigans in Colorado was shocked to find CCTV footage of a black bear wandering into the premises through the back door. At the time of the incident, no one in the bar had actually noticed the six foot beast.
