Blood and chocolate chip cookies.

A great many fish, especially those in the bass family, have sharp spines along the ridges of their backs and on the strongest bone or two of their fins. The spines of red snapper are not only sharp, but also poisonous. The fish produce bio-toxins that ensure that when we fishmongers stab ourselves in the knuckle with one of the spikes, as we often do, we'll have a joint that is swollen, limited in its range of motion, and in a good deal of pain for a few days. It is one of our more interesting battle wounds, and we count ourselves luckier than ordinary predators: at least we don't take it in the mouth. This time, however, besides the usual symptoms I was also given an interesting series of red lines tracing their way up my forearm, at first in the shape of a tree as it followed my veins, and then converging and spiraling most of the way up my arm. Blood poisoning! What a clever fish! The doctors and nurses were all fascinated, as apparently this sort of reaction usually takes a week or two as opposed to a bit more than a day, and not many of their patients come in with fish related injuries. They even had to do research in order to give me an exact diagnosis. The people for whom I work were kind enough to cover the expense of my visit to the hospital and my medication, and to pay me for the time during which I was at the hospital instead of work. Even better than that, the amazing Tom and Erica were extremely good to me, visiting me in the waiting room and bringing me a cookie. All of fishkind, meanwhile, rejoiced, having finally taken their revenge.
