Maggots

I was in the hospital, laid up with a broken leg when the word got out that zombies were on the loose.
No guns. No machetes. Just fire extinguishers and the occasional bone saw.
That’s when it hit me.
“Maggots eat dead flesh,” I said. “Release a bunch of maggots and they’ll eat the zombies.”
The nurse went down to the stockroom and brought out three trays of maggots.
“Is that all?” I asked. “I was hoping for huge barrels full of the things. Maybe fill a moat with them.”
No.
Bar the doors. And pray the army shows up.
