Day likely had its origin way back in the 15th Century. But today it's become more of a day for marketing mischief by big brands.

This year's April Fools' Day marketing stunts feature everything from a grass keyboard from Yahoo to a 5-year cruise from Duolingo and Carnival.

Automakers use April 1st as a means of grabbing people's attention and creating interest and laughter. EpicVIN says that according to the statistics, brands that play along on April Fools' Day have a 10-15% boost in social media engagements in the first week of April.
