Minecraft wiki entry for Villager_(old), 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 players' current skin to turn into villager skins. This also caused users to be unable to change their skins. Different career villager skins were used, including the then-unused nitwit villager (green robe).
