What happens

Grampa, a wrinkled old man in a straw boater and red shirt, plays a blue upright piano on a stage with red curtains while Apu, with blue-black hair, grins from the right and Mrs. Krabappel, with her tall brown hairdo, watches from the left in front of an audience that includes Marge's blue beehive. Grampa keeps playing, grinning, then leans back and stretches one arm out toward the crowd, and the audience's heads shift slightly as he does. In the final moments a spiky-haired boy in the audience raises a finger while Grampa keeps playing at the piano.
