The Mummy knows best of McMasterdonia is a gargantuan, environmentally stunning nation, ruled by The Queen Mother with an iron fist, and remarkable for its avant-garde cinema, rampant corporate plagiarism, and devotion to social welfare. The compassionate, cynical, humorless population of 27.716 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 85.0%, and even higher for the wealthy.

The frighteningly efficient McMasterdonian economy, worth a remarkable 4,221 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 152,304 Livres, and distributed extremely evenly, with little difference between the richest and poorest citizens.

The nation's faithful often say there is a higher power watching over them, internet trolls are considered valiant supporters of the right to free speech, in a baffling press conference The Queen Mother proudly dismantled a broken door, and only The Queen Mother's friends count in the eyes of the government. Crime, especially youth-related, is totally unknown, thanks to a well-funded 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 287,155^th in the world and 4,136^th in The North Pacific for Nicest Citizens, with 2.14 average smiles per day.
