Mother Lion and Father Lion went hunting, and they told their two children not to wander away.

However, a couple of small gnus wandered by, and the baby lions could not resist trying out their own hunting skills.  The baby lions ran and chased the gnus. They killed them, and started eating them.

Just as the baby lions were reaching the end of their meal, the parents appeared in the distance.  One of the baby lions turned to the other, and said:

"That is the end of the gnus.  Here again are the head lions."
