Don't be fooled today!
One of the most famous pranks was by the BBC in 1957 when their Panorama programme broadcast a fake film of Swiss farmers picking freshly-grown spaghetti. The BBC were inundated with requests to purchase a spaghetti plant, forcing them to declare the video as a prank on the news the next day!
Most April Fool's Day jokes are far less elaborate, however, and usually just involve telling a friend or family member a fib, to see their surprised reaction.
So, pay attention to what your friends or family say to you today, as you could be about to be fooled!
