The wet paint sign

When I was younger, me and my friends were fond of making mischief like executing a prank to fool people. One such prank is the wet paint sign. But we do it not for a prank but to reserve a bench in the village park. It never fails unless the would-be victims were already victimized before.

Until now I have been seeing wet paint sign but maybe it is not a prank since it is usually in the mall and not in the park anymore. According to one neighbor, the wet paint sign is a symbol of progress. And I believe him because wet pain means the object is painted to make it beautiful.
