There were once two bulls who were waging war against one another.
As the bulls tore the ground, snorting and bellowing, the frogs who lived in a nearby marsh watched the two bulls fighting.
"Alas!" said the chief of the frogs. "This is bad news for us indeed."
"I don't understand," said another frog. "What difference does it make which bull wins and which loses?"
"Stop and think!" said the elder frog. "The winning bull will drive the loser away, and when that bull comes here to our marsh seeking sanctuary, just imagine all the frogs he will trample underfoot."
