The Mummy knows best of McMasterdonia is a gargantuan, genial nation, ruled by The Queen Mother with an iron fist, and notable for its museums and concert halls, national health service, and absence of drug laws. The compassionate, cynical, humorless population of 23.852 billion McMasterdonians are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The large, corrupt, well-organized government juggles the competing demands of Education, Healthcare, and Defense. It meets to discuss matters of state in the capital city of Intelligentsia. The average income tax rate is 86.1%, and even higher for the wealthy.

The frighteningly efficient McMasterdonian economy, worth a remarkable 3,579 trillion Livres a year, is quite specialized and led by the Tourism industry, with major contributions from Arms Manufacturing, Book Publishing, and Information Technology. Black market activity is rampant. State-owned companies are common. Average income is an impressive 150,061 Livres, and distributed extremely evenly, with little difference between the richest and poorest citizens.

School cafeterias serve nothing but protein powder and vitamin supplements, oxygen is commonly known as 'breathinium', farmers have taken to hunting billionaires who encroach on their land, and Loud Patriotic Music Day has been ranked the seventh best new holiday of the year. 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 243,575^th in the world and 4,482^nd in The North Pacific for Largest Furniture Restoration Industry, scoring -3.46 on the Spitz-Pollish Productivity Index.
