Somebody actually took the time to create this electronic version of “Rock, Paper, Scissors.” Purchase a pair of the keychain-size devices, push a button, and one of the 3 preset images appears on its display. Along with the ease at allowing the gadget to make the decision for you is also the ability to psych out your opponent, but maybe that’s a good thing. At least your odds are 50/50. The game is available at Prank Place for $8.89 a pair.
