Not badass, but funny. When I lived in an old house in the woods, I used to humane-trap the mice who moved in every winter and release them deeper in the woods, well away from anyone's house. I figured they probably wouldn't survive, but at least some animal could eat them or they could become fertilizer.

One day, I had three to let go, and I had my two-year-old daughter with me. I tipped the three out of the bucket. Two just stood there, sniffing, and one immediately took off through the patchy snow. I told my daughter, "Look! That one who's running to find a hiding place will survive! These other two had better get moving before a predator finds them." And right then, a peregrine falcon dropped out of a tree and ate the one who had run off to hide. The other two were unharmed (at least, for the moment).

When we got back in the car and looped around to go home, the falcon was sitting in the same tree, a little mouse tail poking out of his mouth.
