You should not ask.

Do you know what amazes me? The military capabilities of ordinary dog shit. Where did dogshit learn to hide in the grass and ambush people? You don't see it, then a minute later it's attacking your foot. Have the Pekingnese been poking their nose into Sun Tzu? Whole platoons of joggers disappear into dogshit traps each morning in this neighbourhood. If the Viet Cong had been as smart as dogshit the Americans would never have won the war.
