When I was a camp counselor in training one summer we had a relatively small snapper in a tank in the nature center. Everyone was told not to mess with it. Once of my fellow trainees was not the brightest bulb in the chandelier. He stuck his hand in the tank and got a nasty bite on his finger. He may have needed stiches. It was so long ago I cannot remember. Stupid is as stupid does. Needless to say, he did not get offered a job at the end of the training period.
