April Fools' Day is an annual custom on 1 April consisting of practical jokes and hoaxes. Jokesters often expose their actions by shouting "April Fools!" at the recipient. Mass media can be involved with these pranks, which may be revealed as such the following day. In one famous prank in 1957, the BBC broadcast a film in their
Panorama current affairs series purporting to show Swiss farmers picking freshly-grown spaghetti, in what they called the Swiss spaghetti harvest. The spaghetti-tree hoax was a three-minute hoax report broadcast on April Fools' Day 1957 by the BBC current-affairs program
Panorama, purportedly showing a family in southern Switzerland harvesting spaghetti from a "spaghetti tree." The news report was produced as an April Fools' Day joke in 1957, and presented a family in the canton of Ticino in southern Switzerland gathering a bumper spaghetti harvest after a mild winter and "virtual disappearance of the spaghetti weevil." Footage of a traditional "Harvest Festival" was aired along with a discussion of the breeding necessary to develop a strain to produce the perfect length of spaghetti.
Panorama cameraman Charles de Jaeger dreamed up the story after remembering how teachers at his school in Austria teased his classmates for being so stupid that if they were told that spaghetti grew on trees, they would believe it. At the time, 7 million of the 15.8 million homes (about 44%) in Britain had television receivers. Pasta was not an everyday food in 1950s Britain, and it was known mainly from tinned spaghetti in tomato sauce and considered by many to be an exotic delicacy. An estimated eight million people watched the program on 1 April 1957, and hundreds phoned in the following day to question the authenticity of the story or ask for more information about spaghetti cultivation and how they could grow their own spaghetti trees; the BBC told them to "place a sprig of spaghetti in a tin of tomato sauce and hope for the best."
