Furniture Fight is the national sport of Toasterland and it involves two teams (or potentially more) alternating between buying and placing furniture and vandalism and shooting missiles at the other person's house, with the better rated house winning. This results in most of the population being skilled with missile silos and rocket launchers and citizens can defend any towns that come under attack, even if they never need to.
Similar sports elsewhere include Rouketopolemos, the Greek tradition of rocket "war".
