Here's one for the hilarious Russian sign collection. There tends to be a lot of signs everywhere in Russia; I actually have a book that is all about this phenomenon. These signs range from pronouncements of love (there is a huge graffited sign on a wall near my house that says "I love you Zhenya!") to announcements for work ("Excavator needed--call Ludmila 91-64-89") to all sorts of funny prohibitive and warning signs (there is a sign in the shower room at my gym that says "Wash yourself more accurately please!"). I always wonder what the provocation for these signs was. This sign, for example, was in the bathroom of a museum in Suzdal. It says, "Do not stand up with your feet on the toilet!."
