Banned in San Antonio: Pissing on the Alamo memorial next to the actual house drunk while you're wearing your wife's clothes is ill-advised. Thankfully it only lasted a decade.
Creative Differences: He fired Zakk Wylde because he felt that Zakk's songwriting was beginning to make his songs sound like Black Label Society and Ozzy wasn't too happy about that. This prompted him to fire Zakk, albeit on friendly terms. Ozzy's also said this is why he's never worked with Rick Rubin. Rubin wanted to make a heavier, Sabbathy album while Ozzy wants to get away from that. This was also part of the wedge between Ozzy and Sabbath. Ozzy just wanted to make straight up rock music while Sabbath were experimenting with jazz and strings.
Dye Hard: Used to be, anyway. In the 70s his hair was his natural brown. In the 80s he dyed it blonde. Back to brown for the 90s, then when The Osbournes surfaced in 2002 he'd dyed it black with red streaks. It's brown as of 2010, but we'll have to wait and see if it stays that way.
Made on Drugs: In his own words, "for the last God-knows how many years, I've been a major practicing drug addict and alcoholic", now claims to be completely drug-free, and that his 2007 album Black Rain was the first one he's ever recorded while sober. He did revert to his old ways at some point in the early 2010s, but has since brought himself back to sobriety. Given his advanced age and weakening health, it's doubtful that he'd be baking himself again other than the maintenance medicine he has to take out of necessity.
One of Us: Blizzard Entertainment hired Ozzy for a commercial for World of Warcraft. He likes it. They gave him his own character model (though that was actually cribbed from existing character parts to better resemble the real-life Ozzy rather than a bespoke model).
What Could Have Been: Prior to Osbourne's appearances in World of Warcraft and Guitar Hero, he was slated to appear in the Dark Fantasy combat flight sim Ozzy's Dark Skies by one-time developer iROCK Interactive, which was to feature his likeness and music both from his stint with Black Sabbath and his solo career. However, licensing issues and other related complications such as the impact of 9/11 on the entertainment industry according to an article forced the developer to drop the tie-in with Ozzy and release the game as Savage Skies.
