I saw this on our trip to the mountains yesterday. These signs were everywhere in the little community where we were looking for property. During my college years I thought it would be cool to have a band and call ourselves "Slow Children"! Then you could make posters and album covers in this style, perhaps putting the signs in strange and inappropriate places, places where kids wouldn't want to be or play.
Never mind the fact that I wasn't very good on the guitar and couldn't read music. But then, that hasn't stopped some people from making it big!
