I think there have been some famous jokes in the history of April Fool's Day, such as BBC spaghetti tree, the white lion in the Tower of London, the color TV with Swedish stockings and the Loch Ness monster. Although April Fool's Day is not a traditional festival in our country, many people like April Fool's Day very much, because on this day, everyone can make jokes and play tricks on people around them at will. Therefore, there were many memorable April Fool's jokes on April Fool's Day, and these jokes will still make people laugh when they think about it now.

On April Fool's Day, BBC TV broadcast such a news. The general content of the news is that the mild winter has effectively controlled the pests of bread trees, and a farmer in southern Switzerland has achieved a bumper harvest of spaghetti. The news picture shows a woman taking down the spaghetti from a tree, because many British people had never seen Italian food at that time, so many people thought it was a mistake in the BBC news broadcast. But in fact, this is an April Fool's joke played by BBC TV.

The white lion in the Tower of London is also a very famous April Fool's joke. On April Fool's Day, many Londoners received an invitation. The Tower of London wanted to show the citizens a white lion, so many people waited at the gate of the Tower of London all day on April Fool's Day. But in fact, there are no lions in London, let alone very rare white lions. However, many people believed the joke and waited for a long time under the Tower of London.

When Swedish people can only watch black-and-white TV programs, TV stations broadcast such a news that as long as a silk stocking is put on the TV, the TV screen will change from black-and-white to color. Many people believe this statement, so on April Fool's Day, stockings in many shopping malls are sold out of stock. But obviously, this is just a joke. It is impossible for a black-and-white TV to become colorful because of a silk stocking.
