Ferdinand was the most selfish cattle beast in the herd. For example, when the cattle were all driven through a gate into a fresh pasture, every animal would begin to eat the grass just inside the gate. Not so, Ferdinand.
Ferdinand would stroll to the far end of the field away from all the other beasts. That way he wouldn’t have to share. He had all the fresh grass in the world. Several days later, by the time the herd reached the far end of the field they would say to one another, “Where has our grass gone? How come there is no long grass here in the field? Someone selfish must have been eating it.”
That is why Ferdinand was the fattest bull in the herd (and therefore the first to go to the slaughter house).
