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, public floggings, and punitive income tax rates. The compassionate, cynical, humorless population of 22.665 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 84.4%, and even higher for the wealthy.

The frighteningly efficient McMasterdonian economy, worth a remarkable 3,467 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 152,992 Livres, and distributed extremely evenly, with little difference between the richest and poorest citizens.

The monarch frequently needs protecting from misfiring protection, new arrivals are asked the location of the Minister of the Interior's birthmark, McMasterdonians suffer not the eggplant emoji to live, and military minds worry that 'the blue screen of death' on brand new operating systems may be a literal description. 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 263,477^th in the world and 5,769^th in The North Pacific for Largest Cheese Export Sector, scoring -7.9 on the Mozzarella Productivity Index.
