I've been wearing a "Save the Keith Hospital" powerband for weeks now. Unfortunately, millions of people wear powerbands for a miriad of different causes, so people tend not to read them anymore.
Last Friday, however, I had a winner. My hairdresser spotted my powerband and read it aloud, "Save the ... kitten ... hospital"
"Save the KEITH Hospital" I corrected her hastily.
"Cute!" She replied, oblivious, "I donate to the Guide Dogs"
