Here's one that just happened. I was taking some pics of my Demo Man for a guy who was interested in buying it. I had to move it out from the wall to get pics of the side. So I start moving it out. The plug was looped around another machine's leg. Oh well I guess I will unplug it. I unplug it and take a bunch of pics of the sides. Then I take off the translight to take some pics of the boards. I see the batteries sitting in there. Oh, I guess I may as well change them. I take out the batteries . . . and lose all of my settings and high scores!
That is lame, I always like it when there is a bunch of high scores on a game when I buy it. Oh well.
