Prime Minister Menachem Begin ordered the destruction of an Iraqi nuclear reactor near Baghdad in 1981. This action delayed an Iraqi bomb by at least 15 years. The whole world condemned Israel - only to realize later how farsighted it had been.

Part of the new morality of the '60s and '70s is a new attitude toward homosexuality. The homosexual men and women have organized to fight for acceptance and respectability.

It's very different doing a food show in America and doing one in Britain. I did a 20-part series for the BBC series called 'Eating With the Enemy.' The budget for all 20 episodes was probably the budget for a single episode of 'Top Chef.' It's the difference between making a home movie in your backyard and going to Hollywood.

There's a game called Checkout where there's grocery items and it's how much you think the manufacturer's suggested retail price is and we add up your total, then your total has to be within $2 of the regular total. I don't think I could ever win that game.

When I read Frank Miller's 'The Dark Knight Returns', I think it's a wonderful record of the Reagan era. I think it's amazing. This is the time I lived in.

Our emphasis on political coverage from the day we were born here was well-founded, and we believe there were opportunities there that we could do it in a more interesting, appealing and balanced way.

Good enough is never good enough when extraordinary is expected and is the standard.

I did parallel entrepreneurship, which was very hard to do. It was hard to keep your head straight and know which ideas were with which company.

I get really upset some days and I really just wish I had someone there to cuddle.

There are all the activist groups on every imaginable topic - solidarity groups, environmental and feminist groups - sectors of these movements do very valuable work.

Why do we do basic research? To learn about ourselves.

Basicly what I had to do was do a 7 minute board and pitch it to a room of big wigs from the network and based on that they determined if I would get a short or not.

Never give up. Have hope. Expect only the best from life and take action to get it.

I love the way my weight fluctuates in the newspapers. It was 18 stone and then people look at a bad picture of me and add a few more stone on. I think the highest was 22 stone.

We too, through lack of knowledge and of sufficiently mature reflection, mistook the visible outward appearance of the phenomenon for the phenomenon itself.

Ronald Reagan and Margaret Thatcher did more to liberate people by defeating the Soviet Union and freeing eastern Europe than the Obamas, the Clintons, and Kerrys of this world ever have. They were all on the wrong side of that debate.

February days are a marketing gimmick love happens every day.

If I really like the smell of something - a piece of tar or my goddaughter's plastic doll - I put a tiny piece in a bottle with a label. I keep them in a fridge in my bathroom.

I watch a lot of 'National Geographic.'

I think sometimes I don't realise how much the pressure gets to me.

I've been fortunate that when Frank Sinatra was in concert, he would say, 'Here's a song by a wonderful young songwriter, Jimmy Webb,' and I'd be in the front row and stand up. That gets people talking about you.

I loved planning 'The Tyra Show' more than actually having to do it. I loved coming up with show ideas, honing each program and crafting it. I'm more excited being in a meeting than being on TV.

It was a strangely disorienting feeling to have something youd relied on for so long start to change like finding out that gravity no longer worked on Mondays.

How do you cut off the human side and just maintain being professional? So what I've done is I've incorporated that with Kojak - there's times when he allows the human condition, the human experience, to integrate into him as a professional.
