What odd Xbox Glitches have you run across?

I had one in Ninja Gaiden where I was trying to wall run to reach a platform(shortly after the first fight with Doku, with the moving platforms and switches, etc.), and somehow I got transported to the top of the structure. I didn't mind, it saved me a lot of time and effort.

Hey,
Well, technically speaking it's the game that glitches and not the system itself. Lets see, I have a bugged version of Vice city and all sorts of crazy things happen on that game. Morrowind is filled with bugs as well, the best glitch on Morrowind is when actual houses dissapear and only the windows are left visible, so there will be windows just chillin' in mid air

The size of the controllers? :lol

Well, my system had a window that poped up that said Hollywood (my Xbox) needed repair...............I never did anything, worked fine ever since.
