Here's one i came across of the other night(evidentally a true story).
quote:
A motorist was unknowingly caught in an automated speed trap that measured his speed using radar and photographed his car. He later received in the mail a ticket for 40 Pounds and a photo of his car. Instead of payment, he sent the police department a photograph of 40 Pounds. Several days later, he received a letter from the police that contained another picture...of handcuffs. The motorist promptly sent the money for the fine.
