Left image: a person wearing white pants and high heels on a road filled with water.
Right image: a person wearing white pants and high heels, but her pants are soaked in water when viewed from the back.
The image is funny, as when looking from the front, girl's pants are spick and span, while looking from the back, her pants are soaked in water, probably due to walking on a road filled with water in high heels. This is ironical, as the very reason for wearing heels (i.e. looking beautiful) is defeated, due to the heels themselves.
