I'm not 100 percent sure what is going on in this picture, but it looks like a good time! The subject in the center of the frame only works for me because of his emotion and that you do get a sense that this is an "organized group." While this image isn't exceptional, I think it's effective because you really feel what's going on. The actual concept of a laughing club seems a little forced to me unless these people are REALLY funny, but other than a couple of members of the group who look like they're working at it, it seems that laughter really is contagious. It worked in Mary Poppins, why not India? Laugh on.
