FUUUUUUUUUUU

A person in a classroom wears a large Scooby-Doo mask, holding it in front of their face, then removes it to reveal a young man in a green shirt, followed by a young woman in an orange shirt, and finally a young woman in a blue shirt, all smiling and reacting with surprise and amusement. The setting is a brightly lit classroom with a whiteboard and a green wall.
