One of you blokes gave me a fright I will never forget, I was young and working on the 8th or 9th floor of a building, early seventies, I was talking to this doggie, and he just stepped off the landing, grabbing the cable and swinging his foot onto the hook and he was gone. The next time I saw him I told him that he had given me a big fright, he just shrugged his shoulders and smiled. I will never forget it
