I think that might have been "Nostrildamage," because someone belted him hard on the beezer, giving the Prophet a bloody nose. By not predicting this important event, he lost most of his clientele and ended up "geeking" (biting the heads off live chickens) in a medieval sideshow.
Jeanne Dixon died about 25 or 30 years ago, having failed to predict the date of her own demise. Still, she sold plenty of books! Almost as many as that other late self-adoring fraud, Susan Sontag.
Both of them have been replaced by a more up-to-date stooge, Prince Harry of England (who actually exists, but
just for comic relief, only he doesn't know it— and he never will, like William T. McGonagall)
http://www.mcgonagall-online.org.uk/Harry (Nazi uniform and all) will eventually become a "poet," just like his dimwitted father is a "painter."
We're lucky indeed that we don't have royalty in this country...
...except for the Bushes.
