Mine was when I was fighting a Master Ice Mage. I had managed to get stuck in one of those open barrels and couldn't jump or Whirlwind my way out. Luckily I had Spellbreaker armed and was able to defend my self while I threw fireballs at her. I couldn't get unstuck, so I ended up loading back at the start. Was pretty funneh though.

I glitched through the map and got stuck INSIDE the Throat of the World. All because I used Become Etheral to jump down...what svcks worse was that I hadn't saved in a long time...

Ouch! That's one way to make your game choke. LOL

Fence outside Whiterun, fml. and a Dragon decided to show up. glorious, not a **** was given that day.

A rock....and..a hard place.

I once thought I'd be super-sneaky and drop down on a bandit fort from the mountain directly behind it. Nu-uh. Bad idea. I jumped, missed it and ended up getting lodged in the skinny little crack between the fort and the mountain. With Cicero giggling maniacally at me from above, no less. "And if I spy a singing bird, I'll snap its neck before it's-" "STOP SINGING AND GET ME OUT OF HERE, YOU PSYCHO!"

Somewhere in Skyrim's equivalent of an arctic sea. I swam, and my Xbox froze. Not exactly getting stuck, but it was a nice replacement for hypothermia.
