One of the few acts I can remember seeing on America’s Got Talent was Prince Poppycock (aka John Quale) from the 2010 season. No doubt his audience on this Mississippi riverboat will never forget him either, but some of the crew seem to be getting more of a show than they really wanted from this roguish dandy; frowns are spreading, and a knife has been brandished. I just hope that the good prince knows how to swim.
