re: If walking on a path and someone is approaching from the other direction in your side

I throw an old rusty nail down in their path, step to the side, and let fate take its course.

If the great creator lets the nail land just so and keeps the guy from spotting it, I win. Bonus points if his tetanus shot isn't up to date. Lock jaw is a risk you take when playing fast and loose with the rules of sidewalk etiquette.
