The Mummy knows best of McMasterdonia is a gargantuan, genial nation, ruled by The Queen Mother with an iron fist, and remarkable for its strictly enforced bedtime, public floggings, and absence of drug laws. The compassionate, cynical, humorless population of 27.306 billion McMasterdonians are ruled with an iron fist by the dictatorship government, which ensures that no-one outside the party gets too rich. In their personal lives, however, citizens are relatively unoppressed; it remains to be seen whether this is because the government genuinely cares about its people, or if it hasn't gotten around to stamping out civil rights yet.

The large, corrupt, well-organized government juggles the competing demands of Education, Healthcare, and Environment. It meets to discuss matters of state in the capital city of Intelligentsia. The average income tax rate is 83.6%, and even higher for the wealthy.

The frighteningly efficient McMasterdonian economy, worth a remarkable 4,156 trillion Livres a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is a large, well-organized, quite specialized black market in Tourism, Arms Manufacturing, Book Publishing, and Information Technology. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is an impressive 152,220 Livres, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Talkative students are escorted from schools in second-hand prison buses, the nation's police officers are famously miserable-looking, the media seems excessively interested in what The Queen Mother is wearing this season, and it is illegal to have the wrong clock time showing on your microwave oven. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. McMasterdonia's national animal is the McMasterdonian Lion, which frolics freely in the nation's many lush forests, and its national religion is Flemingovianism.

McMasterdonia is ranked 300,372^nd in the world and 4,416^th in The North Pacific for Largest Pizza Delivery Sector, scoring -17.59 on the Pepperoni Propulsion Productivity Index.
