Pha ha ha

A man in a blue sweatshirt and jeans walks toward the camera, smiling and gesturing with his hands, then turns and walks away, repeating this motion in a loop. Another man in a green jacket stands in the background, and a woman briefly appears in the foreground. The scene takes place in a large, empty room with white walls, a light-colored floor, and rows of black chairs against the back wall, illuminated by overhead fluorescent lights.
