Dear Ann: Are you familiar with the McLuhan Dew Line Newsletter? The last issue carried as a bonus a new deck of playing cards called the "Dew Line Deck." It is for the playing of management games as well as the conventional games. On each card there is an outrageous aphorism, such as "Thanks for the mammaries” If anybody deals a card or two to a group of associates or subordinates, or if a single card is picked by the Chairman, the request is: "Relate this aphorism to your top hang-up”.
