Chockfull of hubris and dark whimsy are three stories to remind you to keep your nose clean. Two mischievous, prank-playing boys stumble onto a discovery that's a far cry from child's play in "The Shaft.” Then, a would-be mass-murderer hits a critical point in his development in "Dr. Bizarre." And, in the deep South, a cocky young jazz musician­-who happens to be a hare-makes a deal with the devil in "Bre'r Hoodoo."
