He holds a cardboard box of Cinnamon Toast Crunch and presents it toward the camera, keeping a neutral expression. To his left a television can be seen, and to his right a maroon venetian blind covers a window; a white object is visible behind the blind. A poster is mounted on the wall in the corner of the room. He remains largely stationary while displaying the cereal box.",
