I had a boss that would bring a football to meetings sometimes. Only the person holding the football could talk. We had an agressive know it all, arguer and for the first time I saw him calmed down (as much as possible) However, intead of focusing on the meeting, he just kept trying to get the football, haha.
This seemed like an effective way to control participation and break the monotony. Obviously, I would use it primarily for group discussions, but can anyone see any drawbacks or add anything to this idea?
