Oh okay, I didn't know about this, thank you for the information. 

I have deepened your research and I have found that In 1957, the BBC aired a segment on their program “Panorama” that showed footage of Swiss farmers harvesting spaghetti from trees. Many viewers were fooled by the footage and believed that spaghetti really did grow on trees. This hoax is now known as the “Spaghetti Tree Hoax” and is considered one of the greatest April Fool’s Day jokes in history. It is funny don't you think ?
