I'm a fan (and you should be too) because...
Black Sabbath was the original metal band. Ozzy was and is an amazing singer and performer.
He still ROCKS. He is timeless and eternal and totally incapable of being boring or predictable.
He is a legend and his Fans are legion. If I were asked "If you had the chance to meet any celebrity
who would you choose?", my answer would be "Ozzy Osbourne" I love you Ozzy.
