Minecraft wiki entry for Villager, associated text: On April 1, 2014, Mojang announced that villagers have taken over the skin servers and content delivery networks (CDN) as an April Fools joke. This caused the player's current skin to turn into villager skins, and caused users to be unable to change their skins unless modifying the launcher .json file. Different career villager skins were used, including the then-unused nitwit villager (green robe).
