Are you bored out of your mind that you have absolutely no casual game worth playing on your desktop to kill time while waiting for the clock to turn 5? The Wind Up Sumo Wrestlers might help – all you need to do is wind them up using the spinner knob located at the top of their heads and you’re good to go. Available in red and blue color (to tell the difference between your racer and the opponent’s), you won’t have to worry about replacing them batteries due to the wind up nature. Just make sure you don’t get overzealous and snap the spring within in the process. Each pair will retail for $9.95.
