- Ozzy appeared in a British television commercial for butter substitute I Can’t Believe It’s Not Butter in 2006
- The advertisement coincided with a relaunch of the product in England, from its recipe to its package design
- Just like the product itself, the ad features Ozzy and an impersonator, portrayed by British impressionist Jon Culshaw
- In the ad, the duo follow a cooking show to create pastries, but balk at the recipe name (“Fairy cakes? I’m The Prince of Darkness, I’m making rock cakes!”)
