That's like making fun of a maniac because his brain isn't completely right, because he isn't in the norm.

There was a reason my first substantial role after rehab was to play a maniac whose personal story ended badly. I knew what it was like to go those dark places. I played a guy who died as a result of his abuse.

What do I know about Mitt Romney? I know that he's a self-serving egomaniac who puts himself first, who has a chip on his shoulder, and thinks that he should be president of the United States.

This is my costume. I'm a homicidal maniac. They look just like everyone else.

It's up to us, the people, to break immoral laws, and resist. As soon as the leaders of a country lie to you, they have no authority over you. These maniacs have no authority over us. And they might be able to put our bodies in prison, but they can't put our spirits in prison.

Back in 1948, a monomaniac called Korczak resolved to impose Crazy Horse's likeness upon a mountain. It took 50 years to complete the head, which measures 90ft from crown to chin. By comparison, the four presidents at Mt Rushmore seem modest.

When I'm not running, I cycle about 30 miles a day. I use the biking as cross training. I'm kind of a maniac. I race everybody.

Performing doesn't turn me on. It's an egomaniac business, filled with prima donnas - including this one.

Much in the way Olympic athletes optimize their game by paying an enormous - borderline maniacal - amount of attention to things like diet, exercise, sleep, and of course the essential R&R, we all would do well to pay more attention to those key aspects of our lives that comprise our overall health equation.

My friends are all megalomaniacs - from Damien Hirst to Jack Nicholson - all of them.

Time will tell whether I am a wing nut or a megalomaniac. The difference between a cult and faith is time.

I haven't had the egomaniac star yet in any of my films. It's always been a pleasure.

I used to be a mean maniac. Someone once threw a firecracker at a show and I jumped off the side of the stage and whacked 'em on the side of the head.

We should stop selecting leaders from a subset of Oxbridge egomaniacs with a humanities degree and a spell as spin doctor.

I feel like I've always been a great fighter but I'm learning the patience part of it and not getting overwhelmed with emotion and adrenaline and going out there and brawling like a maniac.

Any man who wants to be president is either an egomaniac or crazy.

I've learned not to be as maniacal as I used to be.

There's not too much Edge in Adam Copeland, but there's a little bit of my sarcasm and my sense of humor, I guess, but I'm not a sleazy, raving maniac like the character of Edge could be.

No movie influenced me more to go after my dreams than 'Flashdance.' After seeing it, I took 15 dance lessons a week. I cut all my sweatshirts. I did the 'Maniac' thing.

A monomaniac is a sick person whose mentality is perfectly healthy in all respects but one; he has a single flaw, clearly localized. At times, for example, he has an unreasonable and absurd desire to drink or steal or use abusive language; but all his other acts and all his other thoughts are strictly correct.

When you make movies the way I do, you invest everything you have. And you do it like a crazy maniac.

From Italy, I'd get calls from cousins and aunts saying, 'I don't think you should act. It's really tough. What are the chances?' This was around the time 'Flashdance' came out, and I was like, 'What about your dreams? I'm a maniac.'

So I'd say that the Doc Antles, the Jeff Lowes, these people were very guarded. Carole Baskin wasn't and Joe Exotic, wasn't, obviously, because he's such a narcissist and an egomaniac that he did so many things against his better judgment.

I love heights. I love speed. I'm on the verge of being a pyromaniac. Maybe my phobia is boredom.

I got interested in computers and how they could be enslaved to the megalomaniac impulses of a teenager.

We are incapable of leaving anything to the imagination and loath to leave anything out. Maniacal thoroughness has become our national verbal ideal.

Actors are real egomaniacs. They get into a movie, they think the whole movie's about them.

Black people need some peace. White people need some peace. And we are going to have to fight. We're going to have to struggle. We're going to have to struggle relentlessly to bring about some peace, because the people that we're asking for peace, they are a bunch of megalomaniac warmongers, and they don't even understand what peace means.

Ch'in Shih-huang is the first emperor of China. He united seven separate kingdoms into a single nation. He built the Great Wall and was buried with the terra-cotta soldiers. The Chinese have mixed feelings about him. They're proud of the nation he created, but he was a maniacal tyrant.

Have you ever noticed that anybody driving slower than you is an idiot, and anyone going faster than you is a maniac?

I think any politician, regardless of their religious conviction, has to be a megalomaniac - they have to be! Anyone who works in that kind of job has to be so full of himself to do that kind of thing.
