Speaking of safe codes, I was at a hotel in Japan (I think the Tokyo Hilton) and my son was playing with the safe. I thought why not, what could he do? Well, turns out he punched enough buttons to actually lock the thing. The safe design was such that the guest set the code, so we had no idea what the combination now was. We would have just left it, but weren't positive that he didn't put something in there first. So, the manager had to come to our room with a suicase full of electronics, plug into the safe, and reset the combination for us.
