At the Sensoji temple in Tokyo, babies face off to see who can be more terrified of a 400 lb. man in a nappy:
The first to bawl is declared the winner. The ritual is a wish for the good health of the children, as crying reputedly is beneficial for babies... If both babies begin crying simultaneously, the child who cries louder is proclaimed victorious, according to Frommer’s.Further indignity ensues for the infant who touches the ground outside of the ring. These babies don't stand a chance.
