Ellen Degeneres set the OSBOURNES a tough challenge during an appearance on her U.S. TV talk show - the foul-mouthed family had to donate $1,000 (£650) to charity every time they uttered a swear word.
Black Sabbath frontman Ozzy appeared on The Ellen DeGeneres Show on Friday (05Feb10), along with his wife Sharon, son Jack and daughter Kelly.
But the new American Idol judge wasn't prepared to accept any bad language from the family - and they agreed to give money to help aid efforts in Haiti every time they cursed during the show.
In a post on her Twitter.com page, Kelly Osbourne writes, "On a good note every time we swore on the Ellen show today we donated $1000 to Haiti!!!!"
