So men think bees are bad
Because they sting
But bees polinate crops so...
Of course create a machine to replace them
Nanobot Bees
They become sentient and happen to like flies
So the flies & bots get together
Re-animate dead cattle
Zombie Humans are slow
Zombie cattle are seriously dangerous
Hit a deer in your car you lose a windshield
Hit a cow in you car you lose your family
