Mischievous brothers Butler and Pagart sneak in the bathroom before their older brother gets up and they put itching powder in his gym shorts and then secret themselves behind a dressing screen to watch the fun. They are treated to a display of Joe making muscular overtures to his mirror reflection, and even once cheating on his arm measurements, mistakenly secure in the knowledge that no one is looking. Charles mimics Joe for George's approval and they have a fine time. When Joe at last puts on the shorts and begins to wiggle as if he had the St. Vitus dance, the boys are so torn with glee that they literally roll with laughter and inadvertently knock over the dressing screen betraying their presence. The incensed athlete quickly surmises the situation, throws a boy over either knee spanking them soundly and liberally sprinkling the itching powder where it will do them the most good.
