Fallout 3 - At the pit, the guy who dies from hunger, walks through the stuff that are in his way, like instead of using the stairs to go up,he goes through them. So all you would see is his upper body!xD
Elder Scrolls: Oblivion - The dog in the fighters guild in Anvil likes to walk in the ceiling! xD It also likes to vibrate like crazy! xD Everytime I go near it turns upside down and turns in all direction!
I stole a horse from this woman and I noticed she was still on the horse when I rode it! Then when I talked to her, on the same horse we both were on...together....I seemed to be talking to a random person instead of that girl who owned the horse and there was no one else around us. xD
I jumped from house to house and went on the walls of Anvil. I jumped down form it and I find myself in total blue! It seemed as though I was under the ground though! Inside the ground was the sky! I heard that I was in danger because of the music but I didn't see anybody or anything. But I did saw plants though... FLOATING.... plants. But I knew someone was there because someone was attacking me, even though I saw NO ONE!
So I flung my sword everywhere and killed the invisible guy. When I kept of walking ahead in the sky underground, it said I had found a farm when i saw nothing... again!
There were a lot more funny glitches but I don't feel like typing anymore.
