"Koraiya!" shouts someone in the audience, acclaiming the actor center stage. Feeding off the adulation, he launches into his next line. "What a useless fellow you are," he yells, berating the servant at his side. "You shall pay dearly!"
"Koraiya!" someone else yells from the back of the theater — again urging on the star by calling out the name of the actors' "house" to which he belongs.
Then, in an explosion of grimaces and angular motion, the actor pounces on his servant, snatches a staff from his grasp, raises it aloft and brings it crashing down on the man's shoulders.
