This is, maybe, the most gratuitous use of an ass in an ad I've ever seen.
See, what Mentos is doing here with their new chewing gum print campaign is place different ads in specific magazines. The above ad is only running in Maxim, where the drooling doofuses are sure to spend much more time looking at the product than they normally would.
Pretty stupid and somewhat ingenious, at the same time.
The below wardrobe malfunction execution is running in entertainment titles.
