Episode: "Best Friends Forever" (s9e4)
Original Air Date: March 30, 2005

In the greatest struggle of any time (that's one heavy superlative), the demons of hell rise up to force the armies of heaven into open war. They are lost without direction, and the angels are unable to provide the leadership needed to win the day. Only a human boy, Kenny, can grasp the golden PSP firmly in his mitts and play Heaven vs. Hell to turn the tide of battle. Now we know who actually plays PSP games anymore.
