That boy is dumb as a
fencepost. What a fencepost. They gave that guy a license to drive, he is dumber than a fencepost. What a twit, a fencepost in a
farmer's field is more usefull than that
fellar. Careful now, don't get too close to that
Fencepost friend of yours, his stupidity might rub off on yah.
Abbrievation: What a post!
