Ok so the other day I was playing Skyrim and trying the new Asteria mod and something weird happened. When I entered a room with mannequins they were walking around for a bit :3 Are they just NPCs stuck in one position? Because when you approach them to give them armor it says give as if you were giving it to a companion. Proof: http://www.youtube.com/watch?v=iNzKScRCsus
Not surprising, that's how Obsidian got a skeleton to wear a dress in the first DLC. Add a glitch to make them act like NPCs and you have an instant moment
