Ozzy Osbourne once painted a hotel room with the blood of a 'dismembered shark' back in his Black Sabbath heyday.
Bandmate Tony Lommi reminisced about the wild days he had with the rock star and how Ozzy would always take things to the next level.
In an interview with New York Post where he was promoting his book Iron Man: My Journey through Heaven and Hell with Black Sabbath, Tony said: “With drugs, always you get bored, so you must do something to one another.
"Like Ozzy hauling a shark through a window, dismembering it and soaking our room in blood,” he added.
It became a tradition for the band to tear up their hotel rooms in drug-fuelled binges and the group would often play tricks on each other.
Another time saw Ozzy set drummer Bill Ward on fire, leaving him with third-degree burns on his legs.
Tony said how Ozzy asked: "Bill, can I set fire to you?", to which Bill casually responded: "Busy, so not just yet."
Later on, he told the Prince of Darkness: "I'm going home now, so if you want, you can set fire to me."
Tony then threw "a bucket of alcohol" over Bill and Ozzy set him on fire.
This isn't the only 'prank' with animals involved that Ozzy has attempted; he once snorted a line of marching ants.
He also bit the head off a live bat, which he insists he didn't know was real "until it was too late".
This happened at the Des Moines Veterans Memorial Auditorium over 40 years ago after an audience member snuck the innocent creature into the gig.
“I always liked old movies that used to have these custard-pie fights,” Ozzy explained in the documentary The Nine Lives of Ozzy Osbourne.
“It gave me this idea to throw, instead of pie, bits of meat and animal parts into the audience. I thought it was hilarious. [They’d throw back] sheep testicles, live snakes, dead rats, all kinds of things.

"Someone once threw a live frog onto onstage. It was the biggest frog I’d ever seen, and it landed on its back.”
“I thought it was a rubber bat,” he said. “I picked it up, put it in my mouth, crunched down, bit into it, being the clown that I am.”
“Bats are the biggest carriers of rabies in the world,” he said. “And I had to go to the hospital afterwards and they started giving me rabies shots. I had one each rear and I had to have that every night.”
