Three children play in a grassy park, with one boy in the foreground making a fist and shouting while another boy in a blue shirt stands behind him; the scene cuts to a man in a football uniform looking up and touching his chin, then back to the children with the boy in the foreground screaming, followed by a shot of a person in a colorful, grotesque costume being lifted by another person, and finally a close-up of the man in the football uniform speaking.
