An old clean one..."The Radar Trap"..

[Stuart G]

> A police officer had a perfect hiding place for watching for speeders
along a well traveled stretch of highway. The location, at a bend in
the road, allowed him to hide his car out of sight of oncoming
traffic while setting up his radar to nab any speeders who passed by.
He had used this location successfully a number of times, especially
on holidays, and decided to use it again on a Labor Day weekend.

The officer arrived at his hiding place and set himself up, settling
down to wait for the first speeders to appear. After a half hour or
so the officer hadn't seen anybody speeding. In fact most of the cars
that passed him were traveling exactly at the speed limit, and some
of the passengers in the passing cars were even smiling and waving at
him. He couldn't believe this was happening since his hiding place
was so well concealed.

Finally, after realizing that virtually all the passing cars knew he
was there, the officer decided that something was wrong and went to
investigate. He got out of his car and walked up the road a short
distance. About 100 yards before his hiding place the officer found
the problem: a 10 year old boy was standing on the side of the road
with a huge hand painted sign which said "RADAR TRAP AHEAD."

A little more investigative work led the officer to the boy's
good friend, another boy about 100 yards beyond the radar trap with a
sign reading ......"TIPS".... and a bucket at his feet, full of change and dollar bills.
