A man was driving through town, when he saw the flash of a traffic 
camera. He figured that his picture had been taken for exceeding the 
limit, even though he knew that he was not speeding... Just to be 
sure, he went around  the block and passed the same spot, driving 
even more slowly, but again the camera flashed.  Now he began to 
think that this was quite funny, so he drove even slower as he 
passed the area again, but the traffic camera again flashed.  He 
tried a fourth time with the same result. He did this a fifth time 
and was now laughing when the camera flashed as he rolled past, this 
time at a snail's pace...
  
Two weeks later, he got five tickets in the mail for driving without 
a seat belt.
