Back in the 1980’s, a friend of mine was working on a paper about some of the action in WWII. One of the incidents he was working on involved an American unit with a British officer seconded to it. He needed more information about the officer, and had no idea how to do that. Someone suggested contacting the Imperial War Museum in London to see if they could provide a lead or source on how to find him. So, he got on the phone and called the Imperial War Museum. He asked the person who answered the phone how he could locate an officer from WWII, and was asked if he knew the man's name and unit. He gave them, and the response was: “Speaking.” In one of the most incredible phone calls in history, he had actually reached the officer who had left the service and gone to work for the Museum, and happened to be walking by a desk when the phone rang. The secretary was away from her desk for a few moments when he happened to walk by and answered the phone.
