Indeed! I also have a magazine article about a nature photographer who accidentally got between two irate boar hippos having a territorial disagreement- one grabbed him by the leg and flung him *40 feet* out of the water and into a bush. He had a hole in his leg he could pass a coke bottle through without touching the edges of the wound...

Also, stupid tourist:
