I had a monkey foolin around the food bin, the villagers chased him off and he had been hiding bananas. I gained 200 food. It happened again and I got 400.
I had vials that poisoned everyone BUT the person who opened it. Only the person who opened it. And some that made them young again.

Also locusts came and destroyed my crops. That's all that is unique (I've had some of the other events mentioned happen as well...
