The Stag, the Wolf, and the Sheep

by Aesop

A STAG asked a Sheep to lend him a measure of wheat, and said that the Wolf would be his surety. The Sheep, fearing some fraud was intended, excused herself, saying: The Wolf is accustomed to seize what he wants and to run off, and you, too, can quickly outstrip me in your rapid flight. How then shall I be able to find you when the day of payment comes?

Moral:
Two blacks do not make one white.
