The Grim Adventures of Billy and Mandy is a gargantuan, orderly nation, renowned for its barren, inhospitable landscape, public floggings, and devotion to social welfare. The hard-nosed, hard-working, cynical population of 31.086 billion Billy and Mandyians are rabid consumers, partly through choice and partly because the government tells them to and dissenters tend to vanish from their homes at night.

The enormous, corrupt, well-organized government juggles the competing demands of Law & Order, Welfare, and Education. It meets to discuss matters of state in the capital city of Endsville. Citizens pay a flat income tax of 69.4%.

The thriving Billy and Mandyian economy, worth a remarkable 2,137 trillion scythes a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is broadly diversified, is led by the Arms Manufacturing industry, with major contributions from Woodchip Exports, Uranium Mining, and Door-to-door Insurance Sales. Average income is 68,761 scythes, but there is a significant disparity between incomes, with the richest 10% of citizens earning 215,362 per year while the poor average 16,831, a ratio of 12.8 to 1.

The arms industry is backed by government subsidies and harsh anti-protest laws are in place, Billy and Mandy has designated Endsville as its capital city, teachers regularly paddle unruly students, and phone taps are frequently carried out by the police. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Billy and Mandy's national animal is the Mr Snuggles, which can occasionally be seen sifting through garbage in the nation's cities.

Billy and Mandy is ranked 48,862^nd in the world and 8^th in Ozzy for Most Eco-Friendly Governments, scoring 1,985.19 on the Dolphin Recycling Awareness Index.
