When Motley Crue went on tour with Ozzy Osbourne in 1984, the Crue found they'd finally met their match in terms of excess, particularly drug consumption. Tommy Lee later recounted pulling into a hotel in Florida after having been up all night with Ozzy drinking and snorting cocaine. The story goes that the musicians spotted a line of ants outside the bus and as Motley Crue looked on in disbelief, Ozzy leapt to the ground and snorted the entire thing with a straw.

Most of the time though, Osbourne was ingesting things more addictive than fire ants. By his own admission, he was a practicing alcoholic and drug abuser for 40 years and is as surprised as anyone that he survived it all. When he was fired from Black Sabbath in 1979, he locked himself in a hotel room for three months to binge on drugs and alcohol (listening to Sabbath's terrible albums of the late '70s, it's difficult to see why he was so upset). He got it back together to start a successful solo career but continued to run off the rails of the "Crazy Train"; in the early '80s he legendarily urinated on the Alamo and was arrested and banned from San Antonio, Texas, and in the late '80s he almost murdered his wife Sharon while high.

By the time Osbourne began appearing on the reality show about his family, The Osbournes, in 2002, most of the madness seemed to be behind him but the effect of four decades of depravity was evident; on the show, Ozzy is depicted as largely unintelligible and nearly deaf.
