"US State papers dating from 1994 released under the Freedom of Information Act reveal that, during the Gulf War, the Pentagon toyed with the idea of developing an aphrodisiac bomb that would cause enemy troops to find each other sexually irresistible. An alternative was to make enemy troops sexually attractive to stinging and biting insects and rodents. They also spent 50 years looking into a Who?Me? stink bomb that would produce smells leading enemy troops to think one of them had farted or suddenly developed bad breath." - BBC.
