I have no doubt that every one of us has seen something odd in our textbooks—a name, an illustration or a graph that looks just a bit too odd or completely bizarre for it to be in a textbook.
Of course, to us as kids that was comedy gold and we’d go around showing everyone this unique and hilarious discovery. But now… well, yeah, it’s still super funny, but now it also begs the question “what were they thinking!?”
Believe it or not, there’s an entire Facebook group dedicated to sharing with the world the most ridiculous, yet scientifically accurate and true, illustrations and diagrams that people find hard to believe that they managed to make it into a textbook.
Bored Panda has collected some of the best examples for you to enjoy below. And while you’re down there, why not vote and comment on the ones you’ve liked the most!
