Clay is the clear favourite, but the showdown will be remembered as one of boxing history's most shocking battles, changing both men forever and showing what it really means to win.

The chasm is almost a third of a mile wide, much bigger than any jump he's done before. To make it work, he'll need a custom-made rocket-powered "Skycycle," TV camera crews and - most importantly - a very positive attitude.

Windscale is supposed to be Britain's big leap into the nuclear age, bringing science fiction to life in 1950s Northern England. But in the race to catch up with America's nuclear program, scientists are tinkering with forces they don't fully understand. When the reactor catches fire, no-one knows how bad it could be, or how to put it out. As the reactor workers scramble to save lives, other eyes on Windscale are much more concerned with containing the political fallout and burying the truth.

If you tuned in to late-night WOR radio in 1950s New York, you'd enter the secret world of Jean Shepherd. Shepherd's nonconformist style, off-beat humor and love of pranks gathered a small but loyal following. These "Night People" loved being in on the joke, while the oblivious "Day People" were often the butt of it. Shepherd's show is long gone, but his spirit lives on in corners of the internet. Today, though, Night People go by a different name.

Mike Lynch was often lauded as Britain's answer to Bill Gates. Born into a working-class family, Lynch's incredible intellect and passion for computers led him to become a billionaire tech entrepreneur. But behind the scenes, Lynch was a bully who couldn't bear criticism and was prone to creative accounting.

Until the 1960s, it was deemed too "dangerous" for women athletes to run distances longer than 200m - and a marathon would kill them, or leave them unable to have children. Rubbish, of course. But when Kathrine Switzer signed up for the 1967 Boston Marathon...

In this series, host Jeremy Schwartz explores the scandal at the heart of the McDonald's Monopoly promotion.
