1) Good:
A Desoto, MO policeman had a perfect spot to watch for speeders, but wasn't getting many. Then he discovered the problem. A twelve-year- old boy was standing up the road with a hand-painted sign, which read 'RADAR TRAP AHEAD'. The officer then found a young accomplice down the road with a sign reading 'TIPS' . . . and a bucket full of money. (And we kids used to just sell lemonade!)

2) Better:
A motorist was mailed a picture of his car speeding through an automated radar post in St Peters, MO. A $40 speeding ticket was included. Being cute, he sent the police department a picture of $40. The police responded with another mailed photo of handcuffs..

3) Best:
A young woman was pulled over for speeding. As the Missouri State Trooper walked to her car window, flipping open his ticket book, she said, "I bet you're going to sell me a ticket to the State Troopers Ball." He replied, "Missouri State Troopers don't have balls." There was a moment of silence while she smiled, and he realized what he'd just said.
He then closed his book, got back in his patrol car and left. She was laughing too hard to start her car.....
