Create a surreal, whimsical scene of a white horse standing upright on two legs with a human-like physique. The horse is meticulously ironing a zebra-patterned cloth on an ironing board, giving the impression it is smoothing out a zebra's stripes. The horse’s body is muscular and anthropomorphic, with its head maintaining a natural equine appearance. The scene is lit with soft, studio lighting against a neutral background, highlighting the unusual yet humorous activity. Emphasize a sense of calm and detail in the horse's posture and focus.
