II. The Chicken and the Wolf

     A Chicken spotted a Wolf that was heading straight for his coop and cried, "WOLF!"

     The Farmer, coddled in his Laz-E-Boy, mumbled, "Stupid Chicken!" and ignored the cry, for he had an invisible fence to ward off such intruders. Little did he know, however, that a car accident down the road had hit a telephone pole and tripped his electrical supply. Of course, the Farmer's great-great-grandfather used to respond all the time to a boy that cried, "Wolf" but that was before there were invisible fences.
     Meanwhile, the Wolf leapt in and ate the Chicken.
     The next morning the Farmer saw the white feathers scattered about, put two and two together and thought, "Thank God. Now I won't have to listen to that annoying squawk box anymore!"

Moral: It's not as easy to get human beings to do stuff as it used to be.
