DUmmies are constantly playing Whack-The-Gopher, the old arcade game where the gopher pops up and you are suppose to knock it back in its hole with a mallet. In the DUmmie version, the gopher is "personal responsibility", "logic", "liberty", "truth", etc.
In the arcade it's just a game and pleasant diversion. In DUmmieland it is a mandatory way of life and a full time occupation.
