Along with Will Shakespeare, T.S. Eliot and Noel Coward, among others, the British can also lay claim to memorable (if anonymous) sign authors. Witness this sign on an iron gate outside St. James's Square in London. First there is the sweet misspelling,  "bycycle," which suggests cycling by things. So much more poetic than bicycle, which refers to the mechanics of two wheels and expands to tricycle for three wheels (hmmm, consider for a second, "trycycle"). Then there are the polite phrases, "causing obstruction,"  "danger to pedestrians," and "Please leave them elsewhere." It's the afternoon tea of signs. Who could refuse? By contrast, what would the New York City version say?  "Don't even think of parking here!"
