If you travel a lot, you've probably noticed that signs are almost identical in every country you visit. That's not a surprise - they are usually made in a way that everyone could understand them independent of nationality, and not get into a trouble. However, you will always notice even the slightest change in size or color if it differs from your home town. Of course, slight differences in color and shape is nothing compared to the funny signs you are about to see, because people's stupidity (creativity?) around the world knows no bounds.
