Most of these signs were designed to help people — to get where they’re going, to find a pet, to avoid grievous bodily harm — and yet some writing-utensil-wielding wiseasses felt compelled to come along and totally deface them. We’re so glad they did. Does that mean we value a wry sense of humor or even just a lazy reference to an outdated song over the safety of our fellow human beings? We’re insulted you would even ask. Of course we do.
