Traffic Camera:
 
I was driving one day, when I saw the flash of a traffic camera.  I
figured that my picture had been taken for exceeding the limit even
though I knew I was not speeding.  Just to be sure, I went around the
block and passed the same spot, driving even more slowly, but again the
camera flashed.  Now I began to think that this was funny, so I drove
even slower as I passed the area once more, but the traffic camera again
flashed. I tried a fourth and fifth time with the same results, and was
now laughing as the camera flashed while I rolled past at a snail's
pace.  Two weeks later, I got five tickets in the mail for driving
without a seat belt.

You can't fix stupid!
