What happens

Principal Skinner, a neat grey-haired man in a blue suit and orange tie, stands beside a table in front of a red curtain, where a cake reading "Happy Anniversary Principal Skinner" with two candles marked 20 sits. Bart, the spiky-haired boy in a blue shirt, stands at the table, first gesturing toward the cake and then shaking hands with Skinner. Bart then takes a microphone from Skinner and holds it up, while Skinner speaks into a second microphone, and the two talk together. In the last frame Skinner moves to the left edge of the picture, leaving Bart standing behind him, while a small buzzer with a red light sits on the cake table next to the cake.
