L.A.'s not a good place to grow old.

Being sober on a bus is, like, totally different than being drunk on a bus.

To be a liar, you've got to have a great memory, and I don't have a memory.

Of all the things I've lost I miss my mind the most.

I got rabies shots for biting the head off a bat but that's OK - the bat had to get Ozzy shots.

You gotta be really careful what you bite off. Don't bite off more than you can chew. It's a dangerous world.

All that stuff about heavy metal and hard rock, I don't subscribe to any of that. It's all just music. I mean, the heavy metal from the Seventies sounds nothing like the stuff from the Eighties, and that sounds nothing like the stuff from the Nineties. Who's to say what is and isn't a certain type of music?

I have a saying. 'Never judge a book by its cover'. I say that because I don't even know who Ozzy is. I wake up a new person every day.

I have a genuine love affair with my audience. When I'm on stage they're not privileged to see me. It's a privilege for me to see them.

I can't do anything in moderation.

What is the world coming to?

I knew it was time to get off of reality TV when someone asked me if I sang as well as acted.

When you're young, you're stupid. You do silly things.

Whenever I have a bad day I just think of these people.

I'm about caring, I'm about people, and I'm about entertaining people. I'm a family man. A husband. A father. I've been a lot of other things over the years, which we don't really want to talk about.

Somebody said to me this morning, 'To what do you attribute your longevity?' I don't know. I mean, I couldn't have planned my life out better. By all accounts I should be dead! The abuse I put my body through: the drugs, the alcohol, the lifestyle I've lived the last 30 years!

They say military have the so-called 'secret intelligence' - this amount of intelligence must be very secret, since I've never seen any intelligent military person, nor I have seen any sense in the bloody stupid wars.

I am a raging alcoholic and a raging addict and I didn't want to see my kids do the same thing.

I wish I didn't have to perform 'Iron Man' every night.

I'm a very simple man. You've got to have, like, a computer nowadays to turn the TV on and off... and the nightmare continues.
