It occurred to me that, if I were a cunning and devious individual, I would sponsor an art contest in which there were entry fees, and of course I would dream up some vaguely plausible reason to justify the fees. then I would arrange for one of my pals to be chosen as the winner, provided she split the cash with me. since I would have implied beforehand that the judging process would be 100% opaque (for some vaguely plausible reason), none would be the wiser, and we'd be free and clear to keep pulling this scam until some clever dick uncovered our nefarious scheme.
