Testing, 1 - 2 - 3.................

"This intelligence-testing business reminds me of the way they used to weigh hogs in Texas. They would get a long plank, put it over a cross-bar, and somehow tie the hog on one end of the plank. They'd search all around till they found a stone that would balance the weight of the hog and they'd put that on the other end of the plank. Then they'd guess the weight of the stone."
