Everyone loves a good Photoshop disaster.  Here's a fun campaign from Y&R Brazil that makes use of three such disasters, intentionally manufactured to sell dental floss. The point is, when you have food stuck in your teeth, people notice very little else. (Copy on each ad reads, "Not even that [insert anatomical oddity] gets more attention than mouth without care.") See if you can spot the larger problems in each of the three ads. Via Ads of the World.
