iREPORTERS SIGNED UP
Created April 28, 2010 by
Ha-ha, giggle, snicker. Expressions of amusement come in many equally amusing forms, but researchers say laughter is no joke; many potential health benefits come from these gleeful spasms of real joy.
A movement has sprung up to celebrate the wonders of LOL and ROFL. World Laughter Day is an annual global event on the first Sunday of May in which people do things like show off their unique belly laughs and even participate in laughter yoga.
Will you be attending one of these events? Share your photos and videos and let us hear you laugh. If there isn't a guffawing group near you, put yourself on camera or find someone willing to show off their laughs.
Check out the video at right for some examples of laughter we found in our own backyard, and then go out and find a few cases of the giggles near you. You could be on CNN, no foolin'.
UPDATE: This assignment is now closed. Thanks for your submissions! We linked some off CNN.com and one of the videos is in this package.
