This is why your teacher always told you to check your work. La Redoute, an upscale clothing line in France, recently posted a photo on their online catalog featuring four little kids in their clothing line having a good ole time on a beach.

The problem was someone didn’t do their job and carefully examine the photo before throwing it up on the web. Hence the FULLY-NUDE dude in the background wasn’t noticed until the photo went viral on Twitter!!! La Redoute posted an apology and removed the photo, but of course we all know the screenshots will last forever!
