...It was said of him in a joking way that his legs were bowed like the ribs of the ponies that he rode constantly from childhood... It is told that after a buffalo hunt the boys were enjoying a mimic hunt with the calves that had been left behind. A large calf turned viciously on Sitting Bull, whose pony had thrown him, but the alert youth got hold of both ears and struggled until the calf was pushed back into a buffalo wallow in a sitting posture. The boys shouted: "He has subdued the buffalo calf! He made it sit down!" And from this incident was derived his familiar name of Sitting Bull.
