Sumo wrestlers coaxed 80 babies, all less than a year old, to cry at last Sunday's annual baby-crying contest at Sensoji temple in Tokyo. The tiny winners are determined by who cries first and who wails the loudest. Participating Japanese parents apparently believe the sumo-induced cries are beneficial, with the babies crying out a wish for good health. At the very least, it probably exercises the lungs.

Some babies reportedly refused to cooperate and stayed silent or even dared to laugh in the wrestlers' faces. Or, at least, that was the case until the wrestlers resorted to slipping on their scary masks.
