Oh How I Love Schemes!

A policeman had a perfect hiding place to screen speeding drivers. But one day everyone was under the speed limit, the officer investigated. A 9 year-old-boy was standing on the side of the road holding a huge hand painted sign that read, "SPEED CAMERA AHEAD!" A little more investigative work led to the boy's partner in crime, another boy about 200 meters beyond the speed camera with a sign reading, "TIPS!" and a bucket at his feet full of coins.
