I'm a fan (and you should be too) because Ozzy Osbourne is freaking awesome!!! My sister and I even named our kitten in his honor (but I'm sure thousands of people do that). The first song I heard was Mr. Tinkertrain from No More Tears, but I didn't like him until the beginning of this year. I know it's a little long after No More Tears came out (I wasn't thought of yet), but you can like him and be 13, can't you?
