Zombie locusts
At school, I gave up all the science I could as soon as I could - but I was forced to do a couple of years of biology until the age of 14. Dissection was something that, by and large, came to those studying the subject at GCSE - but we were, just once, allowed to do a minor procedure.

My school had a small menagerie in the biology labs. Among them were locusts. It was the locusts were were to cut up.

Each of us - 25 teenage boys - was given a locust, a tile, and a blade. We were told where to cut the prone and lifeless insects. We were just about to strike... when the locust on my tile moved. The same happened to a couple of others.

THE LOCUSTS WERE REANIMATING!

We were evacuated from the lab.

A plausible explanation is that they hadn't been sufficiently heavily anaesthetised and that we had to get out so that we'd be out of the way while the staff chased the bugs and captured them. Yet the thought that they might have been zombies intent on preemptive revenge for their imminent dismemberment, and that the lab had to be shut for exorcism and strafing with silver bullets is much more satisfying.

no no no no no
exorcisms are for demon locusts, silver bullets are for werelocusts. To dispatch a zombie locust you have to destroy the brain.

I think I may have
just stabbed it through the thorax with my scalpel.

I'd've gone with
the thumb-press-on-head-crunch method.
