Actually, I have far less of a clue about the Ozzies than Cosby. I don't get everything on even cable here in Taipei!
You're in Taipei? WOW! Probably the most shocking thing about the Osbournes is their horrible language- including the kids swearing at their parents. Now that, to me, is not good. But, Ozzy has used himself as an example of what his kids will be like if they drink and do drugs. Their daughter Kelly got a tattoo and told her father, and her father told her he was disappointed, gave her a lecture, and made her go tell her mom. When Kelly did tell her mom, she broke down and cried because she had disappointed her. They do parent albeit in a very unconventional way.
Don't get me wrong, I loved watching the Cosby Show. Each show had a great moral. And in that aspect, it is very Brady-esque.
