What happens

Bart, Lisa and Maggie sit in a row of classroom-style chairs in front of a wall with a traffic light and a door, Maggie on the left in her blue sleeper with a bow, Lisa in the middle in her red dress and pearl necklace, and Bart on the right in his orange shirt. The three start out with mouths open and wide eyes, then grin and smile in turn while their hands stay behind their backs. Marge, with her tall blue beehive and red bead necklace, steps into a doorway beside a glass display cabinet holding a blue trophy and a gold trophy, leaning in and smiling while the three kids glance over at her. In the final frames she stands in front of the cabinet with a sour, squinting look while Bart and Lisa look on with their mouths open, and a small gold trophy and a blue trophy sit on the shelves behind her.
