It's April 1, which means you may have a trick or two played on you – or vice versa. Good Day Chicago dug into the history of the holiday, so that you can at least tell your victims who inspired you.
Some are terrifying. Some are just plain frustrating. But all April Fools' pranks have one thing in common: they're funny, as long as they aren't happening to you.
There are countless ways to keep your friends, family and co-workers on their toes this April 1. As you suspiciously keep an eye out to ensure you're the prank-er and not the prank-ee, it's nice to know where the joy in our humiliation came from.
The exact history behind April Fools' Day is unclear. But rumor has it, in the 1500's France changed its calendar to match the Roman calendar, which resulted in the new year beginning in January instead of April.
Since news traveled very slowly at that point in history, many continued to celebrate their new year in the spring. These people were referred to as "April Fools."
Around the world, the hi-jinks continue even today. In France, the first of April is referred to as "April Fish," where school children tape pictures of fish to the backs of their classmates.
In Scotland, the day is celebrated by sending people on fools' errands to look for things that don't exist, while the British only play pranks before noon. Anyone who does it after is the fool.
The pranks have already started online. Google, Reddit and Twitter are flooded with pranks right now - so be wary when you hop on the internet this morning!
