First broadcast on BBC Panorama on 1st April 1957, a very young Richard Dimbleby revealed the wonderful world of Swiss spaghetti production to millions of deprived and hungry post-war Brits.
(To be fair, back then Spaghetti was not eaten much and was rather exotic.)
Most of Britain were taken in. Even my dad - who is usually brilliant and smart - even the likes of he, totally fell for this gigantic April Fool's joke! Which just goes to show, if you have a serious and very important enough voice, you can hoodwink anyone.
What an inspiration to us all.
