We were lucky enough to get the game of Mouse Trap when we were kids. It is a pity this clever little clip is marred by swearing, but the chap certainly nails it when he asked who could be bothered playing the actual game. All we wanted to do was see the action. I don't think my brother and I ever played the game. At times the mechanism failed for us and I don't remember why. Maybe the surface wasn't level.
If you haven't wasted enough time yet, how about a life sized version?
