Let's get rid of both guns and shoes. There would be world peace. Walk barefoot through lush green grass or through the wet sand as the surf gently laps at your bare feet. Pure pleasure! Who would want to fight?
Or on hot asphalt, on a gravel road, or through a briar patch. Pure pain. But you don't feel like fighting someone else do you?
Eliminating guns and shoes are the keys to World Peace!
