the most dangerous weapon- "tongue"

People say that world has developed many new improved dangerous weapon, or i can rather say that science has develpoed...but then, the age old strongest weapon, which cannot be withdrawn is the "tongue"...chinese emperor mao tse tung said that he could win a war or a battle through just one weapon and that again is "tongue".... Even the nuclear bombs can be defused, but the poison spewing from the tongue cannot be stopped..
so the only thing i will tell is "mind your tongue"...!!:)
