This happened while switching my weapons and having my preview thing of my character open. I switched a gun so the sword is in the gunning position, I dont know how this happened but this is a pretty cool view and would be awesome if when you inspect someone the sword appeared like this :D

I saw that happen with my Levi once. I really wish that was the default pose for it. :<
On a related note, I don't have a screenshot, but I once saw someone charge a Levi...and it was pointing straight up in the air while they did it. No idea how, but it might be related.
