Laughter Cleese!
One actually wonders whether such an idea that is shown in the following youtube clip will help the strees-charged people including the combatants in the conflict zones...would this produce serious peace?
Laughter, after all is a God-given free gift which is unique to humans. Perhaps, we need to learn to use it to our maximum benefit in order to diffuse tension and even as a conflict-resolution tool. One can even visualise a scene in which heavy fighting is taking place, and in that context, a 'weapon' is designed to pump out laughing gas instead of bullets. Imagine, after a few moments what would be the reaction of combatants on both sides. Laughing their heads off? Quite.
