The Crow and the Sheep

A troublesome Crow seated herself on the back of a Sheep. The
Sheep, much against his will, carried her backward and forward
for a long time, and at last said, "If you had treated a dog in
this way, you would have had your deserts from his sharp teeth."
To this the Crow replied, "I despise the weak and yield to the
strong. I know whom I may bully and whom I must flatter; and I
thus prolong my life to a good old age."
