Craziest request: A nose, ear and throat doctor

In his younger years, you can bet that Ozzy Osborne asked for some bizarre items to land on his tour rider and, of course, plenty of booze and drugs. But in 1999? Dude just wanted to stay healthy. As such, he made sure a doctor was on hand to take care of his nose, ears, and throat, just in case. Also, Ozzy needed three tanks of oxygen because, apparently, you can never have enough oxygen. 

Full list of items: Three oxygens tanks available at load-in and the doctor must be able to administer a B-12 shot. Also, plenty of fire extinguishers.
