Not sure if this is necessarily a prank, but I was working on a team that was split in 2. We had a group of senior devs in one country, and junior devs in another (god only knows why, and yes I complained about this a lot).

The "lead" of the juniors was very stubborn and refused to adhere to the official standards, as his way was better.

I was working on an app with him, I was fed up with how badly the app was working, how hard it was to find files etc. So I waited for him to be off on holidays and pulled some extra hours to completely re-do the folder structure, rip out his persistence layer and a few other things.

When he came back he lost his shit and complained to the architect. The architect (also fed up with his shit) told him that we don't have the time to invest in reverting back everything, and loosing all the new features I added on top, especially since the app is now adhering to standards.

Never felt such satisfaction in my life.
