The Brainless and the Clever Dogs

There was a brainless dog and one day it went out without its helpers. A pack of clever and voracious dogs started chasing it down the sidewalk, with the intention of eating it. The brainless dog fell into a hole in the sidewalk, as it was running along, and disappeared. The clever dogs were way too clever to fall into a hole in the sidewalk, and they ran and ran and kept on running, right out of sight.
