From salad to supervirus

Today, I went to the supermarket and completely forgot to buy one of those bags of salad that you leave unopened at the bottom of the fridge for two months until the contents degenerate into slime but then evolve into an entirely new form of supervirus that would be eager and able to totally destroy the human race if only it could get out of the bag.

But fear not: I’ve made a note so I’ll remember to get one tomorrow.
