The doctor considered the question for a moment and then began to tell a story.
“I have an older friend, much like you, he’s an avid hunter and has never missed a season. One day he was heading out to go hunting. In a bit of a hurry, he accidentally picked up his walking cane instead of his gun.”
“As he neared a lake, he came across a very large, beautiful beaver sitting at the water’s edge. It was at this point he realized that he left his gun at home, and so, he couldn’t shoot the magnificent creature. Out of habit he raised his cane, aimed it at the animal as if it was his favorite hunting rifle, and yelled, ‘bang bang’. Miraculously, two shots rang out and the beaver fell dead.”
“Now, what do you think about that?” asked the doctor.
The 87-year-old replied, “Logic would strongly suggest that somebody else pumped a few rounds into that beaver.”
