Sometimes, technical manuals are hard to read and understand. Occasionally, they may even include pictographs that are supposed to help the user better understand the instructions. But what happens when even the pictographs make no freakin' sense?

Visit the Hall of Technical Documentation Weirdness to see this in action. Darren, the site's creator, has put together a short list of some of the wackiest illustrations and drawings from all over the world. And if you find something that would fit well, send it in and he might add it to the others. From the explosive rat to the sign to not put a baby in a box, these are signs that very few people could actually figure out.
