In order to bring smiles to the faces of people in downtown Chicago, local philanthropist Richard Driehaus hired some performance artists to create displays of joy for unknowing pedestrians.

The ‘Get Happy' experiment easily confirmed that joy begets joy. The video, produced by the group, 500 Clown, can do the same for you.

"We hope this gets you happy and we invite you to spread joy to strangers and loved ones anyway you know how. We would love to work with you on creating a 500 Clown Get Happy in your city, neighborhood, town, college or board meeting. Contact [email protected].
