One of the funniest things I've seen recently happened when I was walking up this fairly steep mountain road. Suddenly, out of nowhere, a large bear reared up in front of me. Well, I didn't have much choice but to kill it. After it fell, I looked down, with a mind to skin it, but the carcass had mysteriously vanished.
So I turned and looked behind me, and there it was. Sprawled on the ground, nose pointed downhill, sliding down the mountain path.
I laughed my arse off.
Oh, and this all happened in the land known as Skyrim, of course.
