What happened on April Fool's Day in history?

The most famous joke: BBC- spaghetti tree harvest

It is still far from 1957. On April 1 day, British BBC TV broadcasted a news that a farmer in southern Switzerland enjoyed a bumper harvest of spaghetti thanks to the mild winter and the effective control of pests on noodle trees. In the picture, a woman carefully picked spaghetti from a tree and dried it in the sun.

Because at that time, Italian food was not common in Britain. Many British people don't know that spaghetti is made of wheat flour. Hundreds of calls were made to the BBC. Some people pointed out that the news was wrong, some people were puzzled, and some even asked: How can I grow my own spaghetti tree?

This can be regarded as an example that TV media joined the ranks of April Fool's Day activities for the first time on April 1. Many years later, the CNN article also commented that this is the biggest joke in history.
