on the HP Photosmart 3210/3310 there is a way to play pong, it’s only one player, but hey at least hp’s thinking of you in more than just printing and scanning :D, anyways the trick is to hold the left and right arrow keys at the same time, then on the manufacturer code screen spell out pong on the numpad (for those with the 3210 enter 7664), now go out and enjoy or just freak out the people at your local retail outlet
