I have noticed there seems to be something wrong with the Jarl 'thrones' in Skyrim. At first, I thought that all Jarl's adopted a 'lounging' pose when sitting in their thrones, so I took a quick chance to sit in one when it became vacant recently and no-one was looking.
My character adopted the same pose automatically, laid back, one arm up affecting a royal wave of sorts, one leg thrust out (very unladylike!).
Whatever is in those chairs, Bethesda should bottle it. Seems it's easier to be royalty than I thought.
