The song title S.A.T.O. from the Diary Of A Madman album, is actually his wife's initials (Sharon Arden Thelma Osbourne).
On December 8th, 2003 he was seriously injured while riding his ATV quad bike on the grounds of his Buckinghamshire estate in England. The accident occurred while he was taking a day off from his hectic promotional schedule surrounding the UK release of "Changes" - a duet with his daughter Kelly. He broke his collarbone, six ribs and a vertebra in his neck. The injuries were not considered to be life-threatening, though he has undergone some surgery.

The cover of his 1982 live album Speak Of The Devil was partially censored in some stores. The cover depicted a fanged Ozzy with blood (actually raspberry jelly) oozing from his mouth. The stores put a sticker over his mouth to obscure the "blood". Once Ozzy discovered this, he demanded that the sticker be removed or he would have his record company pull the album from those stores. Not wanting to lose the album sales of an Ozzy recording, the stores adhered to Ozzy's wishes.
Ozzy was arrested in September 1989 after attempting to strangle wife Sharon Osbourne while drunk. He awoke in jail the next day not knowing why he was there. He and Sharon reconciled in October 1990 after Ozzy endured extensive drug rehabilitation.

Daughter Aimee Osbourne opted out of appearing in the MTV reality show The Osbournes, but his and Sharon's two other children, Kelly and Jack, agreed to take part.
Wife Sharon Osbourne is the daughter of his original manager, Don Arden. Arden dropped Osbourne, Sharon took over as his manager, and later married him.
His song "Suicide Solution" created controversy when a fan committed suicide. The fan's parents alleged that Ozzy was responsible and sued him. The suit was cleared completely.
His favorite band is The Beatles, who inspired him to become a musician when Beatlemania spread worldwide.
The cover of his 1988 album No Rest For The Wicked created controversy; it seemingly depicts himself seated and young children gathered around a Satanic shrine.
Every single one of his solo albums (of original material) has gone multi-platinum.
Ozzy has long said that "Suicide Solution", a song about the dangers of alcoholism, was written as a tribute to former AC/DC vocalist Ronald Belford Scott (Bon Scott) who had died an alcohol-related death in 1980. However in 2002, the writer of "Suicide Solution (Ozzy's former bassist and main lyricist, Bob Daisley), revealed that the song actually alluded to Ozzy himself.
In 1981, after signing his first solo career record deal, Ozzy bit the head off a dove during a meeting with some record-company executives in Los Angeles. Apparently he had planned to release doves into the air as a sign of peace, but due to being intoxicated at the time, he instead grabbed a dove and bit its head off. He then spat the head out, with blood still dripping from his lips.

On 20 January 1982, Ozzy bit the head off a bat he thought was rubber while performing at the Veterans Memorial Auditorium in Des Moines, Iowa. Rolling Stone magazine in 2004 ranked this incident number two on its list of "Rock's Wildest Myths." While the Rolling Stone article stated the bat was alive, the woman who threw it onto the stage said it was brought to the show dead. According to Ozzy himself in the booklet to the 2002 edition of Diary Of A Madman, the bat was not only alive but also managed to bite him, resulting in his having to take rabies shots.
Ozzy's 2010 album Scream was originally titled Soul Sucka. But since Ozzy's fanbase didn't like the title, he changed his mind and scrapped the title.
