During the French Revolution, a doctor, a lawyer, and an engineer were scheduled to be executed. The doctor was taken to the guillotine, saying his last prayers. The blade dropped, and jammed halfway down. After some discussion, the guards and officials decided to let him go. The doctor went away rejoicing, planning to open a clinic for the poor out of gratitude. When the lawyer was taken to the guillotine, again the blade jammed halfway down. He was also set free. He left happily, planning to devote the rest of his career to pro bono work. As the engineer was led to the guillotine he looked up at the device and said, “You know, I think I see what’s wrong with it.”
