In this free flash game (a.k.a. work-productivity-killer) found on Arcadeloco (via Kotaku), the object is to keep all the zombies on the screen so that they don’t run off and eat human brains.  Simply click the left mouse botton on a zombie to stun him with your cattle prod and turn him around.  You can compete for high scores on Facebook, and you can play the game by clicking HERE.  The game is OK if you’re looking to waste some time, but stunning zombies?  Meh.  I’d rather blow their heads off with a shotgun.
