So I just found a Horker in Windhelm

I found it particularly amusing when a whiterun guard told me "Keep your hands to yourself, sneak theif" and then promptly sunk into the ground.

I don't get a great many glitches but yesterday while I was trying to escape the area around Solitude after a Dark Brotherhood hit I was attacked by a dragon...then a bear...then my own follower for some reason (don't remember hitting her) then in the middle of that a solitude guard swam up to me over the hill and arrested me.

I reloaded the save.

I've also had my companions being smashed through walls, or random parts of the water or ground becoming invisible.

Once, I decided to start completely over and go though the opening sequence (I don't do that much anymore). Everything started out fine, but when the carts were just about to enter Helgen they freaked right the fuck out and started flying (an amusing if not worrying experience when one is trapped in the cart). Eventually the carts calmed down and pulled into the village. Alduin's scripting was a bit off, not breaking though the tower wall (it was already broken, so I didn't get stuck), but after that everything went like normal. I don't restart the game completely over anymore I just kept the first autosave, guaranteeing a stable start.

My favorite one so far was when I fast traveled to Riverwood to find a Dremora Lord yelling "YOU ARE WEAK!" while killing everyone. Lolthesda at its finest.

One time the main gate of Whiterun and the wall around was completely gone. I was in the town and I tried leaving, and it let me walk straight into Skyrim's wilderness without a loading screen.

Of course, I was nervous about the game freezing, so I immediately went back to town and went in a building. By the time I came back out someone rebuilt the wall and gate.
