This crazy show aired only once and was hosted by Keith Chegwin. Set up as a quiz show for naturists, the contestants were led through various physical challenges including The Chasm of Doom. Here players swung on a rope to collect a fig leaf - remember they were naked.

It got huge ratings and inspired a debate in parliament. Apart from its nudity, many considered it a dud and it even made the top 50 worst British TV shows list.
