The Wolf in Sheep's Clothing

A Wolf found great difficulty in getting any sheep for its dinner, since the Shepherd and his dogs kept a careful watch over the sheep. But one day the Wolf found the skin of a sheep lying in a field, so the Wolf put the skin on over its fur, and strolled down among the sheep. A Lamb followed the Wolf, thinking it was a real sheep, and so, leading the Lamb away, the Wolf ate it up! Yum, yum! And for some time, he succeeded in deceiving the Sheep, Shepherd, and Dogs, and enjoying delicious Lamb suppers.

And, the moral is…

Appearances can be deceptive. Be careful of those pretending to be what they are not.
