There's a town in Austria which just changed its name to "Fugging," as it was previously spelled and sounded exactly like a word considered most vulgar in the English language. They apparently resisted changing their name for a long time, although they had problems with their town signs being stolen. There were also couples who were caught photographing themselves while performing lewd acts in front of the sign.
