Nelson Mandela enter prison as a sweet-natured Spice Girls fan, but emerge from a long incarceration as a terrorist bent on the armed overthrow of the state.

Viewers also feel the pain of geneticists Watson and Crick as, every day, they get further away from understanding the secret workings of DNA. In Brazil, the mop-topped Bororo and Kayapo people claim descent from Beatles tribute bands, whose plane crash-landed on its way to a Beatles tribute band convention.

In this new, economic climate, Dr Sigmund Freud diversifies the business, combining psychiatry with a Veg Box delivery scheme with the slogan "Tastes As Good As Mother's Milk".
