The boy maniac

Two men stand on a stage with a blue, forest-like backdrop; one in a dark hooded jacket and red shirt, the other in a white shirt and red hat, holding a yellow balloon on a stick. The man in the hooded jacket reacts with a series of exaggerated facial expressions, opening his mouth wide in surprise and then forming an 'O' shape, while the man in the hat holds the balloon steady and turns his head slightly toward him.
