I didn’t know the origin of April Fool’s Day. So I looked it up.
“On April 1, 1700, English pranksters begin popularizing the annual tradition of April Fools’ Day by playing practical jokes on each other. Although the day, also called All Fools’ Day, has been celebrated for several centuries by different cultures, its exact origins remain a mystery.”
Sure, no one wants to shoulder the blame for the dumbest holiday ever.
