A Helicopter lost power while flying over a remote Scottish Island and was forced to make an emergency landing. Luckily there was a small cottage nearby. The Pilot walked over to it and knocked on the door. "Is There A Mechanic In The Area?", he asked the woman who answered the door. She scratched her head and thought for a few seconds. "NO", she finally said,pointing down the road, "But we do have a Mc ardie and a Mc Kay". .
