Transcription: I once came upon a forest mammoth who could both count and remember several numbers at a time. His enterprising owner, a logger by trade, would tap a tusk once for each log needed. A pull on his tail would send him off to bring back the requested number of trees. I decided to expand the mammoth's skills by teaching him addition. It was a mistake, however, to have him calculate our restaurant bill. got the total amount right, he delivered the answer in logs.
