One day the Devil came across a bunch of kids playing marbles in the dirt at the side of the road in the shadow of their school bus. The bus had broken down on the way to school; the driver had run off, God knew where.
“Hey kids mind if I join you?” the Devil asked politely, (but inwardly smirking at the prospect of some nice juicy roast kids for lunch).
They didn’t mind so the Devil squatted down on his goatish haunches and played marbles with the kids. But the kids were too good for the Devil — they kept winning, which the Devil found rather irritating. So the Devil started cheating and won a couple games, which made him happy, or at least vaguely satisfied in a limited sort of way, temporarily at least.
