The first Friday of October each year marks World Smile Day, a day to do one act of kindness and make someone crack a smile!

The day was founded in 1999 by Harvey Ball, creator of the now famous yellow smiley face.

He organized the day to recognize that a smile knows no religion or politics and that we should all spread a little happiness. And after all, it doesn't take much effort to smile!
