Every now and then, we hear of some scandalous ad or a product design and we wonder how nobody noticed what was wrong with it.
For instance, a Kinder surprise toy with balloons that read "KKK" should likely have jumped out at some point during the product's development, but sometimes designers can develop a kind of tunnel vision about their work.
To them, the intended meaning is so obvious that they didn't even consider how the final product might look to outsiders.
And as is the case with one German theme park, sometimes the way it looks was the furthest thing from anyone's mind.
