When I was in college, we had the obligatory squirrels in the courtyard/commons area. One in particular was completely unafraid of any of us students. I used to get an apple from the cafeteria, and slice it up w/ my pocket knife; I would then feed it to the squirrels. One day, they were out of fruit, so I just went out to read the paper. The fearless one apparently recognized me and started barking at me. When I didn't respond, the little bugger came over and untied the laces on my hiking shoes. How dare you not bring me any food, you bastard!
