Speeding - Good, Better and Best:
Just outside town, a policeman found a perfect spot to watch for speeders, but wasn't getting many. Then he 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 also found the boy had an accomplice who was down the road with a sign reading 'TIPS' and a bucket full of money.
A motorist was mailed a picture of his car speeding through an automated radar post. A $40 speeding ticket was included. Being cute, he sent the police department a photo of two $20 bills. The police responded by sending the motorist a photo of handcuffs.
BEST: A young woman was pulled over for speeding. A 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 Trooper's Ball.'
He replied, 'Washington State Troopers don't have balls.'
There was a moment of silence. He then closed his book, got back in his patrol car and left.
The versions of this on snopes are pretty funny, too.
