He scolded Ozzy Osbourne for not being wholesome..
It's true, I'm reading Ozzy's autobiography and Ozzy mentions that once his reality show became famous ole Cos' wrote him a letter saying "your foul mouth sets a bad example". Ozzy's wife Sharon wrote back saying "people in glass houses shouldn't throw stones, everybody knows about your affair, which has been in all the newspapers".
Man, Bill Cosby was a piece of work wasn't he? Talk about being and out and out HYPOCRITE!
