Over two years, the city of New Orleans sent Mary Kieff some 226 parking tickets, with fines totaling nearly $20,000. Kieff insisted she hadn't violated any laws. Finally, after a local TV station got involved, the city admitted that she should not have gotten the tickets. Kieff has a "ZZ Top" personalized license plate, and the city uses ZZ as the code for vehicles without license plates. City workers were entering that code in the wrong place, and the result was that she was getting every ticket issued to a vehicle without a license plate.
