Interesting Signs

I had the pleasure of visiting China recently and came across an interesting sign in a *Muslim Restaurants'* bathroom, please be reminded that the majority of bathrooms at so called *Muslim Restaurants* are those flatbed toilets. I found this sign quite amusing:

This sign was placed above the regular toilets we have, it basically says people should not stand on the toilet but rather use the arses, I did not do either, as it was not the most appealing bathroom, hence, I knuiped till I reached the hotel.
Are there any any other interesting signs you've come across on your travels?
