LOL nice. I've never done anything quite that bad, but I have been known to hit Ctrl-Z on my keyboard while I'm writing something down on a piece of paper... doesn't work out so good...
Hehehe... that too! Or when I'm with Paint.Net making a texture and and use spacebar + mouse to roll up/down or the mouse wheel to zoom in/out... that didnn't work at all... Man this is crazy!!!!
