These ads, featuring chairs that appear to have been turned upside down, have been appearing in the washrooms of bars and restaurants all over Toronto. They are part of a campaign by Y&R Canada for Pfizer's Preparation H, which treats hemorrhoids. The ads feature upside-down chairs that turn the legs of the furniture into "spikes," which shows how painful sitting down can be for those with hemorrhoids. Under the picture is a word: "before." When turned the other way, what you see is a comfy chair and the product in question -- Preparation H Cooling Gel.
