Holy Smokes, I don't understand that code!

So you must be the worst developer in the house, because you are the only one who does not understand that piece of elaborate, complex, carefully obfuscated code? Well, after some asking around, it turns out that nobody has a clue what that code does, or why it even exists. There might be opinions, but unfortunately there is more than one, so does the loudest developer’s voice "win"?

We will analyze where code that nobody understands comes from, understand why we cannot accept it, and discuss why you are not the worst developer admitting that you do not understand a piece of code, but may in fact be one of the smartest.
