....so....I once had a friend who was 'enamored' of weapons and thoughts of soldiering and harbored memories of age-old fueds and enmities.(he was a genuine Scot...Armstrong clan)... I thought to try to lighten the air with a cute idea for settling conflicts:

"Hey!", says I, "Lets just issue soldiers a bag of marshmallows and send 'em out to the battlefield and have them throw at each other! When you have 5 dusty, white spots on you, you're eliminated and have to sit down...the army with the last guy standing is the winner!"

He looked at me quizzically for a minute, then nodded thoughtfully.
"Yeah", he says, "that's a good idea, but it would never work in the long run. It would go ok until....", (and he grinned evilly).."...some guy like ME would come along and put a rock inside each marshmallow....and off we'd go again!"
