''The Wolf in Sheep's Clothing'' by Aesop
One day a hungry wolf was wandering around, looking for his next meal. He stumbled upon a group of sheep. Before he made his attack, he noticed a shepherd with attack dogs. He plotted the whole day how he would find his way to the sheep without being caught. He saw in the distance a sheep pelt, laying in a far away area. The wolf made his way to the pelt, placing it upon his own pelt. Shortly after, he walked over to where the sheep were. The wolf would trick sheep, one by one, to lead the sheep away from the others. Once alone, the wolf would eat the sheep. He continued doing this for weeks, enjoying good meals. Appearances can at times be deceptive.
