"Beyond a Shadow of a Doubt" is the For Real Segment for "The Bluebird of Zappiness".


Harry and Harley are outside taking photos when they discover a wad of cash lying on the sidewalk. Looking back at the photos on their digital camera, they figure out that the money must have been dropped by a mysterious man who entered a nearby art gallery. All they can see in the photo is the man’s shadow, but Harry realizes that they can figure out the man’s height by comparing his shadow to the shadow of a fire hydrant the man was standing next to. Since the hydrant’s shadow was twice as tall as the hydrant itself, the man’s shadow must be twice as tall as the man’s height. Once they figure out the magic number, they go into the gallery and are able to return the money to its rightful owner.
