A BULL, escaping from a Lion, hid in a cave which some shepherds
had recently occupied.  As soon as he entered, a He-Goat left in
the cave sharply attacked him with his horns.  The Bull quietly
addressed him:  "Butt away as much as you will.  I have no fear of
you, but of the Lion.  Let that monster go away and I will soon
let you know what is the respective strength of a Goat and a
Bull." 


It shows an evil disposition to take advantage of a friend in
distress.
