Banned in San Antonio: Drunkenly pissing on the Alamo memorial next to the actual house while you're wearing your wife's clothes is ill-advised. Thankfully it only lasted a decade.
Black Sheep Hit: "Close My Eyes Forever", "Mama, I'm Coming Home" (co-written by Lemmy!) and his duet with his daughter in his version of "Changes", his only #1 single.
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.
Hilariously enough, Rubin is the producer on Black Sabbath's 13 album (the first with Ozzy since 1978).
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.
Keep Circulating the Tapes: The album The Ultimate Sin has been out of print since 1995. No official reason for this has been given, but it's widely believed that it's due to an unresolved legal struggle between Ozzy Osburne and songwriter Phil Soussan over the rights to the song "Shot in the Dark."
One of Us: Blizzard Entertainment hired Ozzy for a commercial for World of Warcraft. He likes it. They gave him his own character model.
The Red Stapler: Randy Rhoads' use of a 1974 white (which aged to a creamy yellow) Gibson Les Paul Custom has resulted in prices for said instruments being higher than most other Les Pauls of the era, which are generally looked down on as inferior instruments to earlier and later eras.
