SLIM PICKENS

My mentor James Nelson Ramsey, long the District Attorney of Anderson County, Tennessee, loved to give nicknames to crooked politicians. What does SLEM stand for?

SLEM Self-Loading Experimental Model
SLEM Steve Le Marquand (Australian born actor)
SLEM Site Laboratory Equipment Maintenance
SLEM Snotty Little Ex-Mayor (GEORGE R. GARDNER, St. Augustine's snotty Little Ex-Mayor, who is now paid $1250/month to write dumb 'ole newsletter for the itty-bitty petty City of St. Augustine City Manager, in which he exoriates dissenters and toes the party line). How gauche of SLEM to do so -- SLEM GARDNER's what my East Tennessee publisher would have called a "glorified welfare recipient," a'int he? What do you reckon?

Priceless.
