On his way to work, a driver swerved to avoid a box that fell from a truck. Seconds later, a policeman pulled him over for reckless driving. But another officer had seen the carton in the road. The policemen retrieved the box and found that it contained tacks.
“Nonetheless,” the first trooper told the driver, “I have to write you a ticket.” Amazed, the driver asked why. The trooper replied, “Tacks evasion.”
