On occasion, when he suddenly stopped in this tracks, he would perform with his feet and hands a series of antics so strange that a crowd would gather around him laughing or staring. As if oblivious to their presence, he would either hold out his arms with some of the fingers bent, as though he had been seized by cramp, or he would hold them high and stiff above his head, or, alternatively, close to his chest, when he would agitate them up and down in the manner of a jockey holding the reins of a horse galloping at full speed. At the same time he formed his feet into the shape of a V with either the heels together or the toes. Having twisted his limbs into the required postures, with many corrections and alterations of their relative positions, he would finally take a great leap forward and walk on with the satisfied air of a man who had performed a necessary duty and who seemed totally unconscious of having done anything odd.
