An old wolf was no longer as strong or as cunning as it used to be and the other wolves thought it was just plain silly sometimes. One of these times it was chasing a billy goat which jumped up on a high rock to save her.
'Why do you waste time chasing me?' the goat asked the silly wolf. 'If you want to catch me, just open your mouth wide and I'll jump into it.'
The wolf obliged and the goat jumped, not into the wolf's mouth, but onto its head, landing so hard that the wolf was knocked out. When the wolf woke up with its mouth open, it could not recall if it had eaten the goat or not.
