Believe it or not guys... My strangest encounter was yesterday. I walked in Dragon Bridge and talked to Horgeir, the owner of the wood mill. He complained about his wife. Then, I found his wife... And she was naked!!

And I didn't eh, do it myself. I had a normal conversation with her, and she acted normally. She just had nothing on. I did check on her belongings and she had clothes in her inventory. Afterwards she said I should keep my hands to myself. Fair enough, given the state she was in...

This happened once to me, only it was the random redguard woman interrogation event. The usual dialog between the brothers, "but she doesn't have the scar", as was amply evident. I tried to speak to her, but she just said, "huh?"
Today I saw a couple of other oddities. Approaching Whiterun, I noticed three guys in the road outside the stables. Well, two were standing, the other was literally up to his waist in the road! And it was the same guy x3: http://www.uesp.net/wiki/Skyrim:Louis_Letrush, no less. Later, in Windhelm, I noticed the meat vendor had a sampling of his wares arranged in mid-air before his stall. Then I saw the same thing at Niranye's booth, with various weapons poised in mid-air.
