April Fools' Day is not a national holiday, so no, you don't get to stay at home and play with your Raspberry Pi or read Hacker News all day. But, you do get to the opportunity to join a community of pranksters around the globe who will invariably succeed in some knee-slapping, good humor.
According to Wikipedia, the earliest recorded association to jokes played on others on April 1 can be found in The Canterbury Tales, by Geoffrey Chaucer (which is now in the Public Domain)—written in 1392. How do you think pranks and jokes have been passed down through the ages or years and changed over time?
Is there a prank your family or friends play every year? Is there a common one in your country?
What April Fools' Day pranks have you succeeded in? Which have you never tried?
Part of the open source philosophy is sharing and modification as well as community and participating. So, we wonder, in what ways does coming together as a community and sharing in humor contribute to a more open world?
