On December 3rd, 1948, Ozzy Osbourne was born. We all know him for his solo career, his work with Black Sabbath and his reality show, but to celebrate his birthday, here are 20 things you might not know about the Prince of Darkness:

2. Ozzy’s dad was a toolmaker and his mother worked in a factory.

4. While he was growing up, Ozzy and his large family lived in a small two-bedroom home in Birmingham, England.

6. Osbourne was on the stage at an early age, acting in musicals at his school likeThe Mikado andHMS Pinafore.

7. As a teenager, Osbourne fell in love with The Beatles and has said that hearing the song “She Loves You” inspired him to become a musician.

8. When he was 15 years old, Ozzy left school. He tried many jobs after that including construction worker, plumber, toolmaker, car factory horn tuner and worker in a slaughterhouse.

9. As a teen, Ozzy turned to crime. He once stole a TV but it fell on him during his getaway and he had to leave it behind. He also swiped baby clothes, thinking they were adult clothes.

10. Ozzy spent six weeks in prison after being unable to pay the fine he got when he was found guilty of robbery. His dad could’ve footed the bill but he wanted to teach Ozzy a lesson.

11. Ozzy made some of his tattoos during his time in prison. He used sewing needles and grate polish to carve happy faces on his knees saying they helped him cheer up. He also put O.Z.Z.Y. on his fingers.

12. Ozzy first joined a band in 1967. It was called Rare Breed and featured future Sabbath bassist Geezer Butler. They played two shows and broke up.

13. Ozzy next played with Geezer in the band Polka Tulk Blues, which also included guitarist Tony Iommi and drummer Bill Ward. They renamed themselves Earth and began building a following but had to change the name again after being booked by mistake at a cocktail party. There was another local band called Earth. So they settled on Black Sabbath.
