And the winner is :

1st Place in the 2006 Darwin Awards has gone to a Brazillian garage employee who tried to disassemble a Rocket Propelled Grenade (RPG) by driving back and forth over it with a car. When this technique proved ineffective, he tried pounding the recalcitrant RPG with a sledgehammer. Its explosion took out one other man, six cars and the repair shop .Finding 14 more RPG's nearby, police concluded the missile was being broken up for scrap metal.      It is now.
