Vigilante 8

The infamous commercial of the Nintendo 64 version consists of a school bus dropping off a bus load of kids at a school then screeching off. It then presents shots from the game and later returns to the school, showing the bus on the back of a flat bed truck, riddled, burned and full of holes. Then it pans to the face of a girl who exclaims.."HOLY *BLEEP*" (There was also another version where the bleep was replaced by a horn honking).

This was later banned after the Columbine Massacre and was thought to have conveyed a message of school violence. The commercial can be viewed here.
