Two men were in trouble and in front of a judge. They both were mechanics. One said that all he did was repair cars and at at least a small margin made profit by selling them to the other man or like that to someone, the other was making the cars look better and sell them at a higher price. The judge thought that they were in this together so made profits two time, one by mechanic repairs and then a last time by repairing the looks of the same car.
