Here is a very popular in Russian tech joke, in my humble translation. Why do engineers hate to work with other people's code? Let me try to make an analogy.

Here is a very popular in Russian tech joke, in my humble translation. Why do engineers hate to work with other people's code? Let me try to make an analogy. You are hired to finish building a scientific lab on a distant island. When you arrive, you see half-finished building, a giant (same size than the building) fan and a hot air balloon. In the basement you found a room full of floor mops - about a thousand of these. You clean up the mess, finish all the work, the lab starts it's first experiment and then suddenly after only five minutes scientists are starting running around screaming about toxic gas leak. You call your predecessor. - Buddy, what's up, there's a toxic gas leak, how's that possible? - I don't know, everything should just work, did you change anything? - Yes, I put all those floor mops away. - Why did you do that?! It was meant to support the floor above, where the toxic gas reservoir is! It was too heavy, thus the mops! - Are you crazy to support the toxic gas reservoir with mops? Why didn't you at least put a sign on the door? What do I do now? - Turn on the fan, it will blow the gas away. - Dude, I disassembled the fan first thing, why didn't you put a box of gas masks instead? - Where do I find gas masks? And the fan was a spare from the other project! - This is terrible! We all gonna die here! - Why are you still there? Jump to the balloon and fuck off the damn island!
