Basketball traces its roots to a game that was played in ancient Central America's Inca cities. The game — throwing a goat's head into a hole in a wall — often went scoreless for days. The winners were granted riches and lives of luxury. The losers were decapitated.
The expression "three dog night" originated with the Eskimos and means a very cold night - so cold that you have to bed down with three dogs to keep warm.
(I hope it never gets colder than a "two dog night" in my house or I'll be stealing my neighbours dog)
