Weaponized toe nail clippings
By inserting tiny explosive warheads and micro-miniature guidance systems with Intel chips and gravy into toenail edges, one can conceivably develop a toe nail clipper that will launch the weapon and guide it to its target. One approach was the ancient but reliable JDAM laser target lighting method, advocated by a bunch of grandpas who were stationed in Thailand during the Vietnam War. The dudes who developed the Killer Unicorns video game proposed substituting toe nails for cows and using alien cow catching technology from UFOs shot down over New Mexico and Arizona in the 1950's.
