Here's an ad that's really the dog's bollocks. It's by Grey Mexico for Motor Master floor disinfectant. "What is on your floor is not always on your mind," says the tagline. The ad, though, may be on your mind for some time, and not in a good way. It is topical, though, and Grey confirms it's a real ad. "They don't have big budgets, but they are very willing to use our creativity," a Grey executive in Mexico City says of Motor Master. There's also a cat version of the ad. Via Ads of the World.
