Postal (computer game)
Postal is an ultraviolent computer game made by Running With Scissors and published by Ripcord Games. A trademark lawsuit was filed against Running With Scissors by the United States Postal Service, and dismissed six years later. The sequel, Postal 2, is perhaps better known then the original.
