I have to say this is by far one of the funniest books I have ever read. Some of the stories Ozzy has in there are hilarious. He has quite an interesting history and it is a good read. If I had to recommend one book ever, it wold be this. The one story involves African Hash and a Priest, and I'll leave it at that.
Even non-Ozzy fans will enjoy this, but if you don't like Ozzy you should probably just give up on yourself.
10/10. Best Book EVER!
