Four ladies went to lunch. On the way home they are stopped by a policeman, who tells them that they are driving too slowly. The driver says to the officer, "but sir we are doing 24mph." "Maam" the cop says, that is the Route number, not the speed limit." "Ohhhhhh, Okay sir." After the policeman leaves, one lady turns to another and says "Gee Amanda, maybe that's why the other policeman was so angry when we were driving on RT 138."
