APRIL FOOL DAY
Left-handed Burgers

In 1998, in the USA, Burger King published an advertisement for a
'Left-handed burger'. The advertisement said that the new burger had the same
ingredients as a normal burger, but everything was rotated 180 degrees.
Thousands of customers went into restaurants asking for a 'left-handed burger', and some people even asked for a 'right-handed burger'!
Interestingly, the word 'whopper' can have two meanings. Firstly it can mean 'very big', so Burger King's 'Whopper' means it's a very big burger. The word 'whopper' is also slang for 'a lie'! So the advertisement that says 'Left-Handed Whopper' could mean 'Left-Handed Lie' - which it was!
The Spaghetti Tree

In 1957, the BBC played a famous April Fools' Day prank, now called 'the Swiss Spaghetti' prank. They broadcast a fake news story of farmers in Switzerland picking spaghetti from a tree. Many people fell for the prank, and contacted the BBC asking to buy one of the spaghetti trees! They received so many requests that they had to explain, the next day, that it was just a joke.
