Ozzy Osbourne has a set of memoirs coming out that describe important things in his life and various milestones he has reached. For instance, he describes the infamous biting off the bat's head incident that he thought was a toy:

"Immediately, though, something felt wrong. Very wrong.
"For a start, my mouth was instantly full of this warm, gloopy liquid, with the worst aftertaste you could ever imagine. I could feel it staining my teeth and running down my chin.
"Then the head in my mouth twitched."

Beautiful! You can read more of Ozzy exploits here, but the story and description of the bat incident were so typical Ozzy I couldn't help but post them. Here is a picture of what a bat head might look like.
