@q an online clothing shop decided they needed a placeholder image as a default for all unlisted sales items, and someone had the thought "hmm we should make it something that really makes it obvious we didn't set an image yet, so nobody can ever forget to apply an image", and thus the default foolishly became a picture of Hitler's face, forgetting the golden rule that all processes will eventually fail at some point.

@q on one fateful day, someone hit publish on a listing without setting a product image, and boom. black frilly bra for sale, with Hitler's face as the product image.

someone noticed, took a screenshot, the media picked it up, big mess.
