Actually, MC, there's an interesting story about his sad face. Not sure if you're familiar with the famous Hartford, CT circus fire of 1944, but it seems that they had waterproofed the tent with a paraffin thinned with gasoline. Naturally, it caught fire (there was a story about arson, but I don't know if it was ever proved). Many people died (mostly children), a number of them trampled to death (one little girl known as Little Miss Nobody wasn't identified until a few years ago). Anyway, Emmett Kelly painted that tear on his face in memory of the victims of the fire.
