Many years ago I was driving in central Miami. I stopped at a red light with space between me and the car in front. A old junker pulled tight behind me and a guy came to the open window brandishing a el-cheepo fixed blade knife. Just as he started to talk, I stuck a 4" python on his nose, hard, and pulled the hammer back. His eyes opened very wide while I mentioned it might be a good time to move the car behind me and leave. Must have been the motivation factor of those 6 158gr HP that got his attention, as he left FAST, with a puddle spreading on the ground!
