In episode "34 - Don't you know anything about women" at about 4 minutes in, Kevin wearing a green plaid shirt enters the cafeteria. He stops to look around for a seat. When the camera shows the cafeteria and the students at the tables, Kevin is already sitting in the background, exactly in the spot he will sit down in. Then the camera shows Kevin standing there again and we can see him walking to the seat he was just sitting in.
