Want to be like the legendary member of Black Sabbath and TV personality: Prince of Darkness Ozzy Osbourne? This guide should tell you how.

[edit] Steps

Grow your hair. Get a wig if you want to do it quickly. Not necessary if you already have long hair.
Dye your hair black. Not necessary if you already have black hair.
Purchase and wear black clothes.
Learn to sing. Practice with classic Sabbath songs such as Iron Man and Paranoid.
Purchase and wear gothic jewellery. Silver crucifixes are good.
Purchase and wear sunglasses. Ozzy's are small, dark and round.
Shake while moving. This may be easier if you are an ex-drug addict.
Swear a lot. Drop an F-Bomb into a sentence wherever possible.

[edit] Tips

Ozzy Osbourne also has a wife who is his manager's daughter, two mental kids, lots of dogs and a Birmingham accent. Aquire these for the full Ozzy style. (If you don't know what a Birmingham accent sounds like...umm...find some Brummies and learn.)

Don't actually take drugs to achieve the shaking effect.
People might frown on your biting off bats' heads, urinating on the Alamo, or ant snorting. Be prepared to be arrested, avoided, shouted at, and/or ridiculed.
