This instructional video, from Sid Davis Productions (the people responsible for "ABCs of Walking Wisely"), tells the account of a police officer who brings his little toy drumming bear. Children at a school in apparent California seem to hear the echoing of the little bear's tin drumming in their minds as they suddenly remember what they are told to do when dealing with strangers.
