What happens

Bart Simpson, the spiky-haired boy in an orange shirt, stands in the foreground of a living room while Lisa, with star-shaped spiky hair, red dress and pearl necklace, sits on the brown couch at left. A framed sailboat picture hangs on the pink wall behind them, and a red lampshade lamp with a purple stand sits at right. In the first three moments Bart stares forward with a flat, serious expression while Lisa looks on with wide eyes. Then Bart's face softens into a slight, sly smile, and in the last moment he raises a small blue box in his right hand while still smiling, with Lisa still seated beside him looking on.
