We made a parking sign a couple years ago that said something along the lines of "No parking - This is not a drop-off zone, unattended children will be eaten" or something like that.
Customer had lazy soccer moms dropping off their kids in his private lot every day, and got fed up. He had a funny sense of humor and the whole thing was (obviously) a joke, but it made the news and everything. Karens all over town were quite upset about it. We ended up taking it down so Karen wouldn't get upset when she continued to use his lot for drop-offs, and replaced it with the usual "you will get towed" sign.
Good times.
