In the jump-rope scene, Sailor falls down in one shot while Punchinello recites "Mabel, Mabel". But after the rope changes into two double dutch ropes, he stands up in another shot with Peter. In yet another shot, he sits down on the floor while next to David and Peter who are standing on the left side.
