April fools' day, c'est tout simplement un poisson d'Avril!

Did you know that in 1957, the BBC fooled the nation by broadcasting a documentary about spaghetti crops in Switzerland? It showed women plucking strands of spaghetti from a tree and laying them in the sun to dry! Some viewers beleived that story and wanted to find out where they could buy their own spaghetti bush, and others criticised the BBC for airing an hoax on what is supposed to be a serioux factual programme. At that time in the UK, spaghetti was considered an exotic delicacy.
