The Chicago White Sox may have their Ozzie-- their manager Ozzie Guillen-- but the Cubs also have their Ozzy-- Ozzy Osbourne.
When Cubs announcer Harey Carey was still alive, he started a tradition of singing "Take Me Out To The Ballgame" during the Seventh Inning Stretch. When Carey died in 1998, the tradition was continued. The Cubs always have some celebrity guest to sing it.
Perhaps the most memorable one was Ozzy Osbourne. Yes, that Ozzy Osbourne, on August 17, 2003. Never mind that he's from England, a country where baseball is not played. Never mind that he didn't know the words. The Evil Dictator (the blogger also known as my son) has posted a Youtube clip of that infamous moment, which was obviously an important life event for him, to share with you all.
