Ghostbusters: Every Cameo Ranked From Worst To Best

9. Ozzy Obsourne

Role: " Rock Star" (Seriously, he's not even allowed his own name!)

It's a God-damn tragedy to see what's become of Ozzy Osbourne since the early, glory days of Black Sabbath. He's now a comedy act when he's not on stage with the band (as they wind down their final tour), thanks to those awful reality TV shows. This sort of unnecessary cameo - just because - is the final insult to him and his legacy.

Ozzy turns up as a befuddled, angry rock star during the rock concert sequence that sees a ghost terrorising the audience and Ozzy demanding to know from Sharon if he's daydreaming. It's unimaginative, a waste of an appearance fee and completely pointless: a walk on designed to get a reaction that it absolutely does not warrant.

Why couldn't he have actually been the rock star singing at the gig that actually has his bloody name on the billboard outside?!
