There is an anecdote that I have always enjoyed from the first bio I read of Hannibal Barca, of 'Hannibal ad portas' fame. I heard another anecdote from my amazing wife today that is actually comparable in it's audacity, however (warning, disclaimer, warning) not proper nor condoned by yours truly in any way.
A small but critical Kingdom in what is now Turkey was being assailed by the Roman Navy, and the king knew that a very-aged Hannibal had retired to a small home in exile there after the sacking of Carthage in the Second Punic War. Although he had agreed never to wage war on the Romans as terms of his exile, the King sent an emissary to Hannibal to entreat his help in defeating the Roman Navy. After much persuasion, he reluctantly agreed to assist.
They led him to a bluff overlooking the scene of the battle. The Romans had large (but slow), open and high-walled ships that they were using to ram the smaller and faster local ships. When they couldn't catch them by ramming, their archers would fire through portholes in the side of the ships. They were quickly making short work of the King's inexperienced Navy.
Hannibal stood there silently for a number of minutes, then turned to the emissaries and said 'Get some earthenware jars, fill them with poisonous snakes, and lob them into the Roman ships.' He then turned around and went home. The emissaries promptly relayed these instructions, and shortly thereafter the tide of battle turned as the Romans, unable to easily escape their high-walled ships, died from poisonous venom.
Needless to say, the Roman generals knew that the local king would never have had the brilliant insight with the snake-grenades. They tracked Hannibal back to his home, where he saw them coming, promptly took poison, and died. A tragic end to an amazing career.
Fast forward 2200 years, and there is an anecdote in See No Evil by Robert Baer, the basis of the film Syriana. Baer was an active intelligence operative in the Middle-East, and was relating an story he had heard at CIA training camp (aka 'The Farm'). Another example of out-of-the-box-thinking, albeit very politically incorrect:
"One of the instructors at the Farm had told us a story of how, after the 1967 Arab-Israeli war, the agency's skunk works had come up with the idea of filling a captured Soviet transport plane- Soviet markings and all- with live pigs and dropping them over Mecca, Islam's most holy city. The idea was to light the Middle East's fuse and direct the blast toward the Soviet Union, whose influence had been growing in the area."
I wonder if being exposed to constant bloodshed catalyzes some innovation function in the brain. I am pretty sure two guys didn't think this one up in the stands of their kid's T-ball game.
