A Has Been or Washed up person is someone who was popular, but whose fame has long since faded, along with the quality of their out put. These are the kinds of people who end up with a stage show in Vegas if they're lucky or Branson, Missouri if they're less than lucky, and who appear on reality shows and shows talking about the 80s on VH1 and shows talking about the show that was the last time they were popular, or they may just have disappeared altogether.
Such fate has befallen many once popular icons. However, there are the icons who did not meet this fate. Paul McCartney nor David Bowie were ever forced to do a twice daily dinner musical stage show in Branson. Harrison Ford never became spokesman for a Ford Dealership in Poughkeepsie. But what if they did?
The challenge here is to take people who are popular, and popular still, and turn them into has-beens where their career has disappeared and they are struggling for relevance if they have any left.
