My former sister-in-law, not the brightest bulb in the chandelier, but still quite creative, rolled through a stop sign and THEN spotted the two patrolmen in the cop car watching her do it.
She stopped the car, backed up, stopped at the stop sign, and slowly went on her way again.
She again looked over at the two cops, who were laughing so hard that they could hardly sit upright, and they waved her on!
