Good, better, best

GOOD
A policeman was watching for speeders and was surprised at how few he was catching. He then discovered the problem - a 12-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 used to just sell lemonade!)

BETTER
A motorist was mailed a picture of his car speeding through an automated radar post in the Manawatu with a fine of $160 included. Being cute, he sent the police department a picture of $160 The police responded with another mailed photo of handcuffs.

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