Deception all around

A young jockey in a pink and white checkered shirt and helmet stands beside a brown horse in a stable, holding a yellow sponge and looking up at an older man in a blue robe and glasses who is using a walker. The man, initially smiling, leans forward and then grimaces in pain as the jockey looks on with a surprised expression. The scene takes place in a stable with numbered stalls, including stall 1 where the horse stands.
