Sheepish Shortcut
Bill and Dale built a skating rink in the middle of a pasture. One day a shepherd, leading his flock, decided to take a shortcut across the rink.
The sheep, however, were afraid of the ice and wouldn’t cross it. Desperate, the shepherd began tugging them to the other side.
“Look at that,” remarked Bill to Dale. “That guy is trying to pull the wool over our ice!”
